Semester7

Notes of courses done/attended in semester 7 in college

here we have 4 phases
- inception
- elaboration
- construction
- transition
it is an iterative model
divide big proj into number of iterations
and in each iteration, we will do all parts : designing, planning, testing, coding
some iterations will give me the product releases
each iteration produces a working, executable, product that might not be a deliverable
no rush to code
agroUML, starUML - open source UML tools
early iterations seek feedback from the customer. Risk and value to customer is managed through early feedback
Customer is engaged continuously in evaluation and requirements gathering
Arcchitecture is built during early iterations

udp

Component Based software development
- build s/w system as a set of s/w components interconnected via interfaces
uses the UML
use case driven
- a use case is a piece of functionality in the system that gives a user a result of value
- use cases capture functional requirements
- use case answers the quesion what is the system supposed to do for the user
architecture-centric
- similar to architecture for building a house
- embodies the omst significant static and dynamic aspects of the system
- influenced by platform, OS, DbMS, etc
- related as function (use case) and form (architecture)
iterative and incremental
- commercial projects continue many months and years
- to be most effective - break the project into iterations
- every iteration - identify use cases, create a design, implement the design
- every iteration is a complete development process

must be selected & developed in a planned way i.e. in a logcal order - early iterations must offer utility to the users
- iteration based on gp of use cases extensing the usability of the system developed so far
- iterations deal with the most imp risks first
- not all iterationsa re additive - some replace earlier iterations
