System Request: Business NeedTo increase efficiency and customer service through

the development of a user-friendly, web-based banking information system, which will:

• Allow for maintenance of a centralized database for the managers of Modesto Bank

• Function through an interactive user-friendly website with entry, update, add, and delete options

• Deliver the most recent product information to all managers and officers of Modesto Bank via the internet

System Request: Functionality & Scope

The system (website & database) will have the following functionalities:• Equipped to handle four different types of products, namely:

• Money market products.• Credit card products.• Mortgage products.• Certificate of deposit products.

• Enabled to allow the bank managers to make changes in the products.• Permits multiple users to be able to access the database at any given

time• Secured website interface that will allow easy navigation of various

parts of the site after confirming the login ID and password.• Update/add/delete functionalities to edit the fields in the database to

allow for the most recent information about the products.

System Request: Expected Value

Tangible:• Increased customer service by being able to provide the customer

with the most up-to-date information. Rates will be updated in the timeliest fashion.

• Reduction of paper by not having to print and distribute weekly product rate specification sheets

Intangible:• Recognition of Modesto Bank as a forerunner for incorporating

information technology in their central database.• Increased work efficiency among managers and other top officials• Less possibility for distortion of product information among the

various branches of the bank and the central bank.

Expiration Date – The date of expiration on the product card.

ERD: User TablesThe Access Rights table includes the following features: Rights_ID*- The field used to uniquely identify the right.Add – Right for adding data (It indicates with y/n)Update – Right for updating data (It indicates with y/n).View – right for viewing data (It indicates with y/n).

The Users table includes the following adjustable features: Username*- The field used to uniquely identify the users.Password – The field entered by each userFirst_name – Users’ first nameLast_name – Users’ last nameDepartment – Users’ departmentPosition – Users’ positionRights_ID – The field that is defined rights for each user.

Milestone 3: Requirements

• Completed in 32 hours• Implement our ERD in MySQL

• Make Program Specifications

• Design an HTML Prototype

ERD Implementation

• Done using phpAdmin for MySQL

• See the interface by clicking

Program Specifications Example

1. Insert a new mortgage productSQL Command:

INSERT INTO `mortgage` ( `ProductID` , `MG_Fixed` , `MG_Duration` , `MG_Apr` , `MG_Point` , `MG_OriginationFee` , `MG_MinPayment` , `MG_MaxAmount` , `MG_Offering` , `MG_Expiration` ) VALUES ('', 'n', '5', '4.895', '0.00', '0.00', '5', '500000', '2003-04-01 00:00:00', '2005-04-01 00:00:00');

Program Specifications Example

2. Update the expiration date of an existing money market product.

SQL Command: UPDATE moneymarket SET MM_Expiration = "2006-04-01" WHERE ProductID = "4"

HTML Prototype

Completed in about16 hours

Sized to be printer-friendly

Milestone 4: Requirements

• Completed in 25 hours• Program the site

• Test the site

The Final Product

• Lets go to the site

Testing Documentation

• Pages 32 - 47 of Documentation

• Conducted:1. Black box testing (testing against

requirements)

2. White box testing (testing of coding)

3. User interface testing

4. Use scenario testing

5. Security testing

Problems

• Having the database down for 6 days during the implementation stage

• Learning curve for new technology – none of us knew asp.Net; most hadn’t used MySQL

• Formatting the update text boxes in asp.Net

Where We Could Improve• Allow more time for implementation

stage….or not have the database server go down for 6 days

• Add more documentation to the site so that future programmers could read our code

• Consider using a less constraining design; one that allows for wider tables.

Additional Functions that Could be Added

1. Security. In the current system, even if a user should login with an appropriate username and password in order to get into the bank intranet site, the site is not completely secure. For instance, if a user copies and pastes the url of one of the manager pages, she/he can go to the same page without login. This problem should be prevented with using cookies or session variables.

2. Data validationIn the current system there is data validation for numeric and date fields for all adding pages, but not for the updating pages. Data validation should be added throughout for all the updating pages in case a user makes a mistake during the updating process.

Additional Functions that Could be Added

3. Page Index FunctionIf there is the page index function in the table view page, the search from dropdown menu does not behave appropriately. For instance, when a user views the all product and goes to the second page, a user can not select any other options from dropdown box. With this problem, the page index function was removed from the current system.

4. Sort FunctionFor the column-by sort function, we had to select the exact same table column names as the database. If we named the column name differently for user friendly purpose, the column-by sort does not function appropriately.

What We Learned

• Increased our cooperation & communication skills

• Learned or at least advanced all of our knowledge of asp.Net and MySQL databases

• Increased project management & time management skills
