  • Introduction

    Attempts to make social networking sites began in the early 90s

    Some of the first popular sites were classmates.com (1995) and sixdegrees.com (19

    97)

    Today, there are hundreds of social networking sites, ranging from dating sites to the

    friendship based sites, such as Facebook and Myspace

  • Popular Social Networking Sites

  • Benefits of Social Networking Sites

    Social networking sites are easily accessible

    Helps encourage communication and keep people connected

    Improve communication skills

    Users learn basic and some advanced technological skills

  • Questions:

    Q: Why PHP ?

    Ans: Easy to understand, can be hosted anywhere, cross platform,

    Easy to deploy and nice presentation.

    Q: How HTML and CSS will benefits ?

    Ans: HTML - Easy to code, easy to understand errors, it can embedded

    with CSS and JavaScript.

    CSS It allows you to style the web page.

  • Questions:

    Q: How JavaScript is useful ?

    Ans: It is a programming language used in web pages. JavaScript is the language that makes the web

    pages more dynamic. JavaScript is practically used by every website. It is used in client-side

    Scripting.

    Q: Idea about client and server side scripting ?

    Ans: Server-side scripting is a technique used in web development which involves employing

    scripts on a web server which produce a response customized for each user's (client's) request

    to the website. Server-side scripting is distinguished from client-side where embedded scripts,

    such as JavaScript, are run client-side in a web browser, but both techniques are often used

    together.

  • Questions:

    Q: Which programming approach is better ?

    Ans: Object-oriented programming is suitable for large project and long term maintenanc

    e of software of web projects, this method of programming poses its own disadvantages

    as object-oriented programming tends to be more complex than structured programming

    as there is a lot as far as design the decisions that need to be made and consequently th

    e entire task of managing the project may be a bit difficult to the inexperienced web devel

    oper.

  • SDLC:

    Fig no: 1 SDLC

    SDLC is nothing but a Software Development Life Cycle. It is a process followed for a software

    project within a software organization. The life cycle defines a methodology for improving the q

    uality of software and the overall development process.

  • Zachman framework:

    The Zachman Framework is an enterprise ontology and is a funda

    mental structure for Enterprise Architecture which provides a formal

    and structured way of viewing and defining an enterprise.

    The first are primitive perspectives : What, How, When, Who, Wher

    e, and Why.

    The second is derived from the philosophical concept of reification, t

    he transformation of an abstract idea into an instantiation.

    The framework defines how perspectives are related according to c

    ertain rules or abstractions.

  • Framework set of rules:

    Rule 1 :The columns have no order

    Rule 2 :Each column has a simple generic model

    Rule 3 :The basic model of each column must be unique

    Rule 4 :Each row describes a distinct, unique perspective

    Rule 5 :Each cell is unique

    Rule 6:The logic is recursive

    Rule 7 :The composite or integration of all cell models in one row co

    nstitutes a complete model from the perspective of that row

  • ER Diagram:

  • DFD:

    A Data Flow Diagram (DFD) is a graphical representation of the "flow" of data through a

    n information system, modelling its process aspects. A DFD is often used as a preliminary

    step to create an overview of the system, which can later be elaborated. DFDs can also b

    e used for the visualization of data processing (structured design).

    TYPES OF DFD

    A Physical DFD shows how the system is actually implemented, either at the moment, or

    how the designer intends it to be in the future.

    A Logical DFD attempts to capture the data flow aspects of a system in a form that has neither redundancy nor duplication.

  • DFD:

    Data Flow Diagram : Context level

  • DFD:

    Level 1 DFD :

  • DFD:

    Level2 : Account Level2 : Post articles

  • DFD:

    Level2 : Services

  • DFD:

    Level3 : services/notify Level3 : services/chat

  • DFD:

    Level3 : services/settings

  • Risk Management

    1. Identify: Search for the risk before it creates major use.

    2. Analyze: Understand nature, kind of risk and info about

    the risk.

    3. Plan: Convert them into action and implement them.

    4. Track: We need to monitor necessary actions.

    5. Control: Correct the deviation and make any necessary

    amendments

    6. Communicate: Discuss about the emerging risks and th

    e current risks and the plans to be taken

    week 1

  • Risk Management

    Social network enables you to engage customers in real time, add s

    ales channels, and enhance your brand and market research.

    However, you need to be aware of and prepared for the risks that so

    cial media can bring. These risks include employees leaking confide

    ntial information or intellectual property (either inadvertently or on pu

    rpose), which can result in reputational issues as well as the potenti

    al for legal and regulatory challenges.

    Many organisations are struggling to develop and maintain a clear-c

    ut social media governance framework as a central part of their soci

    al media strategy.

  • Use Case Diagram:

  • Class Diagram:

    Class diagrams gives the static design view of system

    A class diagram shows a set of classes and their relationships

    Contents:

    Classes

    Relationships

    1. Association

    2. Aggregation

    3. Generalization

    4. Composition

  • Class Diagram:

  • Activity Diagrams:

    Activity diagram is basically a flow chart to represent the flow of

    control from one activity to another activity .

    It emphasize the flow of control

    Content:

    Activity states or action states

    Transitions

    Branching

    Forking and joining

    Objects

  • Activity Diagrams:

  • Sequence Diagram:

    Sequence diagram shows the interaction between the classes in ter

    ms of exchange of messages over time

    They are also called as event diagrams

  • Sequence diagram:

    Components :

  • Sequence Diagram:

  • Component Diagram:

    A component diagram shows the organization and dependencies among the a set of component

    Component diagrams are use to model the static implementation view of a system

    Component diagrams the are essentially class diagrams that focus on a system components

  • Component Diagram:

  • Deployment Diagram:

    Deployment diagrams are used to visualize the topology of the physical

    components of a system where the software components are deployed.

    So deployment diagrams are used to describe the static deployment vie

    w of a system. Deployment diagrams consist of nodes and their relation

    ships.

    Deployment diagrams are used for describing the hardware components where software components are deployed.Component diagrams and deployment diagrams are closely related.
