PREREQUISITE

„ For your project you will design, implement

and deploy and online service

„ You will work in teams of 5 member „ Emphasis will be on design, planning, management „ Deliverables every 3 – 4 weeks „ A team presentation is required with each deliverable

OO ANALYSIS & DESIGN

UML

„ WHY NEED DESIGN & ANALYSIS

„ Creation of well designed , robust,

manageable software

„ Not good enough to know an object

oriented language – JAVA, C++, SmallTalk.

„ UML – Unified Modeling Language

„ Graphic notation for modeling systems.

ANALYSIS & DESIGN

„ REQUIREMENT SPECIFICATION –

„ Is the description of problem.

„ ANALYSIS –

„ Investigation of the problem and not the

solution.

„ DESIGN

„ Is finding a logical solution which fills the

requirements.

OO ANALYSIS & DESIGN

„ OO ANALYSIS –

„ Consider the problem domain in

perspective of objects(things, concepts,

entities)

„ OO DESIGN

„ Defining the objects in terms of attributes

& methods.

Analysis Design Construction
