Problem Statement

1)Existing system description:-

The “Green Land Motors Showroom” is mainly a franchise given by the “MARUTI”. The showroom is a retail marketer of Maruti four wheelers.

In the showroom there are 3 main departments: -

1) Employee Information

2) Payroll System

3) Sales Department

All these three departments have their head officer who manages & control all the working. But the information or details about the every employee only can access by the Administrator or H. R. Executive. H. R. Executive manages the detail or information about the Employee Information System & Payroll System and he/she also submit all information of monthly detail..

If any new person got a job in the showroom the interview is conduct or taken by the Administrator or H. R. Executive or head of particular department.

In the showroom all information about Employee Information System and Payroll System is maintained by the H.R. Executive. The H.R. Executive is only made changes in the database or records.

H.R. Executive saw all queries but the employee can see only his/her information.

2)Problem of Existing System:-

In spite of being the newest showroom “Greenland Motors” in Allahabad this showroom two main departments are still untouched from computerization. But by involving us in this project, computerization process starts.

Maintaining crucial data of around 200 employees is difficult in manual process.

There are many problems, which are faced by the office member. They are as follows: -

1. Functionality: - Because there work is done manually, so the there functionality is very low as compared to other department, which are computerized.

2. Time consuming Process: - Each a single process takes lots of time.

3. Processing Speed: - The effort done for the progress of the work is done manually, so the processing speed of the existing system is very low & frustratful for employees.

4. Portability: - The portability of the current existing system is not possible because the information is stored in files, & searching for a piece of information among all those files is very tedious work.

5. Input/Output Interfaces: - The Input/output Interfaces of the current system are very poor. To work with there current Input/Output Interfaces need deep understanding of their work.

(A) Requirement Analysis:

After doing initial investigation the exact need of the user from proposed system is accomplished. Requirements analysis is the most important part of the system development life cycle. The most important phase of requirement analysis is finding information from user. These are the following points, which show what the user requires:

1. Automation of activity.

2. To be totally integrated online system.

3. User interfaces.

4. To develop computerized software.

5. To develop user- friendly software.

6. To create software with error handling capabilities.

7. Less burden of work.

8. Fast and accurate report generation.

9. Paperless Environment.

10. Cost maintenance.

Introduction of Project:-

The Online Employee Information System & Payroll System (OEIPS)deals with the controlling & managing the entire working of Employee Information & Payroll System ,Green Land Motors Allahabad.

There are many activities in the department & he/she want to mange all the activities by a single project.

“Online Employee Information System “gives some flexibility in the project to add, modify or delete new employee in the showroom or add or modify employee’s entries of the showroom.

This project on “Online Employee Information & Payroll System” is basically to help in managing their showroom by converting manually running system to a computerized system & online system. By introducing this current system, that work maintained by the H. R. Executive of that showroom would become easier, convenient & time saving.

A project is a complete information regarding employee. Adding new employee entry or maintain only last one year employee record/details, show the Payroll information of employee. Concurrently Administrator or H. R. Executive can see the stored information. The employee can see only his/her information.

This project is designed as managing & storing information preparation of details, plan or scheme of any engineering undertaking. Thus the project is schematic, consideration, particular object.

What is ASP.NET?

ASP.NET, similar to desktop applications, we can use variables, define functions & make use of a database, even a connection to a remote database is possible .In a summary we can say that ASP.NET is a programming system, to develop dynamic internet pages. This system provides the necessary technologies, like Classes & Objects.

ASP.NET is the platform that we use to create Web Applications & Web services that run under IIS.ASP.NET is not the only way to create a Web application .It is integrated with the Microsoft server, programming, data access, & security tools.

What ASP.NET Provides?

ASP.NET provides a high level of consistency across Web Application development.In a way, this consistency is similar to the level of consistency that Microsoft Office brought to desktop application. ASP.NET is part of the .NET Framework & is made up of several components.

ASP.NET is the most complete platform for developing Web Application that run under IIS. It is important to remember that ASP.NET is not platform independent.Because it is hosted under IIS, ASP.NET must run on Windows servers. To create Web Application that runs on non-Windows IIS server, such as Linux/Apache, we must use other tools generally CGI.

Advantages of ASP.NET:-

ASP.NET has many advantages over other platform when it comes to creating Web Applications. Probably the most significant advantages are its integration with the Windows server & programming tools. Web Application created with ASP.NET are easier top create, debug & deploy because those tasks can all be performed within a single development environment – Visual Studio.NET.

ASP.NET delivers the following other advantages: -

Executable portion of a Web Application compiled so they execute more quickly than interpreted script.

On-the-fly updates of deployed, Web Applications without restarting the server.

Automatic state management for controls on a Web pages so that they behave much more like Windows controls.

The ability to create new customized server controls from existing controls.

Built-in security through the Windows server or through other authentication/authorization methods.

Integration with ADO.NET to provide database design tools from within Visual Studio.NET.

Full support for Extensible Markup Language (XML), cascading style sheet (CSS), & other new & established Web Standards.

Built-in-features for caching frequently requested Web pages on the server, localizing content for specific language & cultures & detecting browser capabilities.

How IIS & ASP.NET manage processes:-

Understanding application boundaries is important because ASP.NET uses these boundaries to determine how the application is run on the server. When IIS receives a request for a resource within a web application, IIS uses aspnet_isapi.dll to call the ASP.NET worker process. The ASP.NET worker process loads the web application’s assembly, allocating one process space, called the application domain, for each application.

In this way, ASP.NET maintains process isolation for each web application. This is different from the way IIS provided different isolation levels for older Active Server Pages (ASP) application running under DLL Host.exe.The isolation level setting in IIS have no effect on ASP.NET applications.

In IIS version 6.0, you will be configuring multiple application pools, each of which can be served by one or more process instances. In addition, ASP.NET is integrated with the IIS version 6.0 kernel mode HTTP listeners, which will allow request to pass directly from the operating system to the ASP.NET worker process.

SQL Server 2000: -

SQL server 2000is an RDBMS that uses Transact – SQL to send requests between a client computer and a SQL Server 2000 computer. An RDBMS includes databases, the database engine, and the applications that are necessary to manage the data and the components of the RDBMS. The RDBMS organizes data into related rows and columns within the database. The RDBMS is responsible for enforcing the database structure, including the following tasks: -

Maintaining the relationships among data in the database. Ensuring the data is stored correctly and that the rules defining data relationships are

not violated. Recovery all data to a point of known consistency in case of system failuThe

database component of SQL Server 2000 is a Structure Query Language (SQL) - compatible, scalable, relational database with integrated XML support for Internet Application. SQL server 2000 builds upon the modern, extensible foundation of SQL Server 7.0.

Objective And Scope

The scope of this project “Online Employee Information & Payroll System” is to manage the detailed information of employee’s i.e. details of field advances, details of various allowances, credited or debited to person’s account.

The GUI provides an easy way of using the Online Employee Information System and Payroll System with minimum of training.

Specific Requirement: -

This section of the SRS should contain all the details needs to create a project. This is typically the largest and most important part of the SRS.

Specific requirements should be organized in a logical and readable fashion.

Classifying the specific requirements is as follows: -1. Functional Requirements2. Performance3. Design4. Attribute

5. External Interface Requirement

1. Functional Requirements: -

This subsection of the SRS should specify what is to be done by the project, to what specific requirement, what input should be transformed to what outputs (not how this is done), what specific operation is required.

For each function, specific requirements on inputs, processing and outputs. These are usually organized: -

I. Purpose of the function: - Provide rationale to clarify the intent of the function.

D). Feasibility Study:-

Feasibility is determination of whether or not a project is worth doing. The project followed in making this determination is called Feasibility Study. The analyst can go ahead and prepare the project specification which finalize project requirement. The preliminary investigations examine project feasibility. These solutions are further evaluated to find out the following:-

Technical Feasibility Economical Feasibility Operational Feasibility Legal Feasibility Time Feasibility

Technical Feasibility:-

In this type of Feasibility we describe specifying equipment and software that will successfully satisfy the user requirement. We should be examined to see if the proposed equipment has the technical capacity to hold the data required. The Technical needs of this system are: Ability to process a large volume of data transaction to fulfill this purpose the application is developed using ASP.NET as front end and SQL Server as back end.

Economical Feasibility:-

In this type of Feasibility we determine the project should be economically feasible by every type of user. A Cost-Benefit analysis is necessary to determine Economic Feasibility. The primary objective of Cost-Benefit analysis is to find out whether it is economically worthwhile to invest in the project.

Cost-Benefit analysis is performing by first listing all the costs association with the project. Costs consist of both direct cost and indirect cost.

Direct costs are those incurred employing people; cost of consumable item, cost of computer, software, cost of system analyst and programmers, cost of material, cost of designing & cost of training analyst and user & indirect costs are phoning charges, land charge.

Benefits can be broadly classified as Tangible benefit & Intangible benefits.Tangible benefits are directly measurable. These are as a: inventories, delays in collecting outstanding payments, wastage. Intangible benefits are better service of

production, accurate, reliable and up to date strategic, tactical and operational information.

Operational Feasibility:-

This Feasibility is mainly related to human, organization and political aspects. Our project operationally feasible due to following: The existing manual work of showroom will be computerizedBeing a ASP.NET GUI & CUI based interface the system developed will be user friendly.

Legal Feasibility:-

The project is legally feasible as it does not violate any law and also provides essential help to the showroom. This project is mainly based on payroll and employee information system.

Time Feasibility:-

This determines that the proposed project can be implemented within the stipulated time frame; in this case it is three months. From the PERT chart of the proposed project it is clear that three months is sufficient enough to complete this project, hence project to be considered.

(B)Cost and Benefit Analysis:-

1) Cost Analysis:-

Cost plays an important role in deciding the application. Therefore, it must be identified and estimated properly.

I. Tangible Cost: - It refers to the ease with which costs can be measured. It includes the purpose of new hardware or software, personal training and payment against any bill- related project, compiler, other needed software and secondary disk manual for the user.

II. Intangible Cost: - Cost that may be known to exist but whose financial values can be measured like the customer and the user or employee specification, already existing set up and the facility costs.

III. Cost of Project: - The cost estimation is none, since the application development has been undertaken as a project work for academic purpose.

2) Benefit Analysis:-

Benefits are also of different types and grouped on the basis of advantages they provide to the management.

I. Tangible Costs: - These benefits include job completion within few hours or producing report more accurately without error. Least paperwork and maintenance of record for longer time are included in this.

II. Intangible Costs: - This include more satisfied employee, improved corporate image. Faster work initiates employers to work more efficiently. Overall satisfying organization or showroom from the project is the main purpose.

F).Structure Chart: -

The documentation tool for structure design is the Hierarchy or Structure Chart. It is a graphical tool for representing hierarchy. They are used to specify the high-level design, or architecture of a computer program. As a design tool, they add the programmer in dividing and conquering a large software problem that is recursively breaking a problem down into parts that are small enough to be understood by a human brain. The process is called Top-down Design or Functional Decomposition.

The first step in creating a structure is to place Class: Main in the root of an upside-down tree, which forms the structure chart.

The next step is to conceptualize the main sub-tasks that must be performed by the program to solve the problem. These sub-tasks are placed in nodes below the roots and connecting lines are drawn from the root to each sub-task.

Next, each sub-task is individually focused and conceptualized how each sub-task can be broken down into even smaller tasks.

Eventually, the program is broken down to a point where the leaves of the tree represent simple methods that can be coded with just a few program statements.

Branches of the tree are assigned as Modules, which are then programmed. Often a process called Bottom-up implementation and testing is used to implement each module. Each node in the chart represents a method (in Object Oriented terms, a method). The root node represents the main method of the program. Each connecting lines are labeled with the parameters of the method represented by the lower node.

A structure chart is a high-level design notation and leaves some coding details unspecified. Specifically, control structure for iteration (E.g. for while) and

selection (if-then-else-end if) are not depicted in a structure chart. The chart only shows the calling sequence of a program and its parameter information.

Rectangle represents a module, connection represented by a line.

Project Evaluation & Review Technique:-

The complexities of the present day management problems and the business competitions have added to the brains of the decision makers. In a large & complex project involving a number of integrated activities, requirement a number of men, machine & materials, it is not possible for the management to take & execute an optimum schedule just by intuition based on the organizational capabilities & work experience.

Management, are thus, always on a look out for some methods & technique which may help in planning scheduling & controlling the project. A project may be defined as a combination of integrated activities, which must be executed in a certain order before the entire task can be completed. The aim of planning is to develop a sequence of activities of the project, so that the project completion time & cost are properly balanced & that the excessive demand of key resources is avoided. To meet the object of systematic planning, the management has evolved a number of techniques applying network strategy. PERT is one of the many network techniques, which have been widely used for planning, scheduling & controlling the large & complex projects.

Prototype Model

In prototyping, a prototype or model based on the gathered requirements is prepared. It is then evaluated by the user and is used to define requirements for the software to be developed. Iterations occur as the prototype is tuned to satisfy the needs of the customer, at the same time enabling the developer to better understand what needs to be done.

If prototyping is used, the changed requirements are known by the developers at every iteration. Since information collection is done at each iteration, new or changed requirements are updated every time.

When the final prototype is ready, what do we do with it? We can do two things:

The prototype can be used as it is since it is actually a fully working model.

The prototype can be partially or fully reconstructed. This is done to suit the needs of implementing on a specific platform, environment etc.

6. Post – implementation

One must progress from one stage to another methodically, answering key questions and achieving result in each stage. The life cycle activities are isolated and sequenced, but in real life they overlap and are highly interrelated. They can be an overlap during any phase of the cycle.

Describe detail description Phases of SDLC

1).Problem Definition: -

One must know what the problem is before it can be solved. Preliminary system survey or initial investigation to determine whether an alternative system can solve the problem. It entails working into the duplication of efforts, existing procedures, whether parts of existing system would be candidate for computerization.

2). Feasibility Study: -

Depending on the results of the initial investigation, the survey is expanded to a more detailed feasibility study. A feasibility study is a test of system proposal according to its workability, impact on the organization, ability to meet user needs and effective use of resources. It focuses on three major questions:

What are the users’s demonstrated needs and how does a candidate system meet them?

What resources are available for a given candidate system? Is the problem worth solving?

What are the likely impacts of the candidate system on the organization? How well does it fit within the organization MIS plan?

The objective of the feasibility study is not to solve the problem but to acquire a range of its scope.

The result of the feasibility study is a formal proposal. This is simply a report – a formal document detailing the nature and scope of the proposed solution.

3). System Design: -

The most creative and challenging phase of the system life cycle is system design. The term design describes a final system and process by which it is developed. It refers to the technical specifications that will be applied in implementing the candidate system. It also includes the construction of programmes and programme testing. The key question here is: How should the problem is solved?

The first step is to determine how the output is to be produced and in which format. Sample of output are also presented. Second, input data and master files (database) have to be designed to meet the requirements of the proposed output. The operational phases are handled through programme construction and testing, including a list of programmes needed to meet the systems objectives and complete documentation.Projected cost must be close to actual cost of implementation.

4). Implementation: -

The implementation phase isles creative than system design. It is primarily concerned with user training, site preparation and file conversion. When the candidate system is linked to terminal or remote sites, the telecommunication network and tests of network along with the system are also included under implementation.

Programming provides a reality test for the assumption made by the analyst. It is therefore a mistake to exclude programmers from the initial investigation design.

System testing checks the readiness and accuracy of the system to access update and retrieve data from new files. Once the programmers become available, test data are read into computer and processed against the files provided for testing.

In most conversions, a parallel run is conducted where the new system runs simultaneously with the old system. This system provides opportunity to the staff to work with the new system as well as old system. In some cases it is not possible to run parallel systems. After the new system proves itself, the old system is phased out.

5). Maintenance: -

There is an ageing process in software that requires periodic maintenance of hardware and software. If the new information is inconsistent with design specifications, then changes have to be made. Hardware also requires periodic maintenance to be in tune with design specifications. The important of maintenance is to continue to bring the new system to standards.

User priorities, changes in organizational or environmental factors also call for system enhancements.

6). Post – Implementation: -

Every system requires periodic evaluation after implementation. The post – implementation measures the system’s performance against predefined requirements. Unlike system testing, which determines where the system fails, so the necessary

adjustments can be made, post –implementation determines how well the system continues to meet performance specification.

A post- implementation is a review is an evaluation of the system in terms of the extent to which a system accomplishes stated objectives and actual project cost exceeds initial estimates.

A).Entity Relationship Diagram

When we design a database for a system, we should first design the entity relationship diagram. It is a diagrammatic representation of what data can be attributed to an entity and what various relationships may be shared between entities.

The Entity-Relationship model for data uses 3 features to describe data, these are:-

Entity: - Entity is anything in a system, which may be attributed by a set of attributes that

define the characteristic of the entity and specify distinct real world items in an application.

(Entity)

Relationships:- It connects entities and represent meaningful dependencies between them. Entities do not exist independently: they depend on each other. They relate to each other.

(Relationship)

(Connections)

Attribute: - Attribute, which specify properties of entities and relationship. HR Executive manages details of all employees.

For Example: - HR Executive and Employees are the entities. The details such as Attendence details, Master details, Salary details, Account details, Special information is also entities. An employee can access all details. The act of accessing details defines a relationship between an employee and details.

An entity set is a collection of similar entities. Each member of an entity set is described by some Attributes.

For Example -An employee may be described by the attributes – Employee ID, Employee Name, Department, and Designation, DOJ, Salary etc.n

A DFD, also known as a “bubble chart”, serves the purpose of clarifying system requirements and identifying major transformations that will become programmes in system design. So it is the starting point of the design phase that functionally decomposes the requirements specifications down to the level of detail. The DFD is a representation of various processes and the input and output in each process. Further it also represents the various data stores.

Symbol Used in DFD’s: -

A square defines a source or a destination of system data. (External entity)

An arrow identifies data flow – data in motion. It is a pipeline through which information flows.

A circle or a bubble (oval bubble) represents process that transforms incoming data flow(s) into outgoing data flow(s).

An open rectangle is a data stores – data at rest – or a temporary repository of data.

Context diagram: - The context diagram is the top level DFD. It represents a system as a single process with only major inputs and outputs to the system represented as data flows. The source and destination of the data as external entities are also represented.

Level 1 and Higher Level DFD: - when we explode the context diagram and break the single process into a number of detailed processes, then level 1 DFD is created. The numbering convention in the DFD is as follows:-

In the Context diagram, no number is given to processes as only one process exists.

In the level 1 DFD, the processes are numbered as 1, 2, and 3.

In the next level, the processes are numbered depending on which process has been broken. If process 2 of the level 1 DFD is broken, the processes are numbered as 2.1, 2.2 and so on.

The processes are numbered as 3.2.1, 2.3.2.1 and so on as further levels of DFD are created.

C).Flow Chart

Flow chart is a diagrammatic representation of a system with processes specifically. The flow chart is a tool which diagrammatically represents the logic of a procedure. It uses predefined symbols for decision making, flow of process and input, output, etc.

Testing:-

The purpose of testing is to identify and correct errors in the candidate system. As important as this phase is it is one that is frequently compromised. Testing is vital to the success of the system. System testing makes a logical assumption that if all part of the system is correct the goal will be successfully achieved.

Inadequate testing or no testing leads to errors that may not appear until months later. A small system error can explode into a much large problem. Effective testing early in the process translate directly into long-term cost saving from a reduce number of errors.

This software is tested module by module; the relationship between modules and the software is validated against preset objectives.

Black box testing or fundamental testing has been used in testing phase of this project. In this, the structure of the program is considered. Test cases are decided solely on the basis of the requirements or specifications of the program or module and the internals of the modules or the program are considered for selection of the test cases.

Levels of Testing: -

In this software mainly three types of testing is used: -

System testing starts by testing program individually. A program module may work perfectly well in isolation but may failwhen interfaced with other modules.The approach is to test each entity with successively larger ones,system testing consist of following steps:

Unit testing Integration testing System testing Acceptance testing

1.Unit testing : An individual program must compile and test data correctly and also bond with other programs in order to run Satisfactory.program testing checks for two type of errors: syntax and logical. A syntax error in program occurs when a statement in a program breaks one or more rules of the language in whitch it is coded.common syntax errors include an improperly define field dimension or ommited keywords.

A logical errors deal with invalid data fields, out-of-range items and other incorrect data combination. Since logical error is not detected by the system, the programmer must carefully study the output for finding the same.

2. Integration testing:

In this type of testing all constituent programs should work properly.program are invariably related to one another and interact with the other system.each program is tested as a combined manner.each program of the System is tested against the entire module with both artificial and real data.

3.System testing:

System testing is done to find out those imperfection that were not found in tests conduct earlier.This include forced system failure and validation of total system as it will be put to use by its userIn the actual working environment.The system is also tested for backup and recovery procedure .

4.Acceptance testing: This testing involves running the system with live data by actual user. This is done to familiarize the user with The validity and reliability of the system.As user motivation and knowledge are important for the successful Performance and implementation of the system.The significance of user acceptance testing cannot be overtested.A comprehensive test report is prepred after testing.This report is tested the systems tolerance ,performance range ,error rate accuracy.

Module: To Delete Employee Information (Only for H.R.)Condition: If Employee ID matches.Input Data: Click on Delete.Output: Records are deleted and display message “Record Deleted”.Test result: Successful

System Maintenance and Evaluation

This project “Online Employee Information System and Payroll System” is developed using concept, logics and analysis of manual working process, which is easy to understand.The data stored using the software package is much more accurate and reliable since it is developed, keeping all security constraint in mind.

The software package uses user-friendly interface. A person with only the ability to interact with the computer system, using the Keyboard can easily interact with the system with a little prior explanation. Flexibility of the software has also been kept in mind to provide maintainability.

Maintenance Process:

To make the maintenance process easy and effective, properly produced and maintained system documentation is provided. These documents are:

A document describes the overall system architecture.

For each component, specification and design description.

Program source code listings are commented.

Validation document describing how each program is validated and how the validation information relates to the requirement.
