Software Process

SOFTWARE PROCESSSOFTWARE PROCESS• The main phases of a software process:

– Requirements Analysis (What?): TextSpecifying what the application must do

– Design (How?): Diagram & TextSpecifying what the parts will be, how they will fit together

– Implementation (Coding)Source and object code

– TestingTestcase, Black Box/White Box

– DeploymentCreate Package Software, Installing Application, Create Documents

– MaintenanceModified design, code and text

Object Technology

OBJECT TECHNOLOGYOBJECT TECHNOLOGY• Why Objects?

– Objects are the enabling technology for adaptive business systems.

• Three Keys to Object Technology– Objects that provide encapsulation of procedures and

data– Messages that support polymorphism across objects– Classes that implement inheritance within class

hierarchies

DIAGRAMS IN UMLDIAGRAMS IN UML• UML have several different types that can be used to

describe a model from different point of views. There are:– Class diagram– Use Case diagram– Sequence diagram– Collaboration diagram– State diagram– Activity diagram– Component diagram– Deployment diagram

DIFFERENT VIEWPOINTS IN DIFFERENT VIEWPOINTS IN UMLUML

• The reason for a lot of different diagrams is that it is possible to look at a system from many different viewpoints.– Analysts– Designers– Coders– Testers– QA (Quality Assurance)– The Customer– Technical Authors
