Software Process

SOFTWARE PROCESS The main phases of a software process: –Requirements Analysis (What?): Text Specifying what the application must do –Design (How?): Diagram & Text Specifying what the parts will be, how they will fit together –Implementation (Coding) Source and object code –Testing Testcase, Black Box/White Box –Deployment Create Package Software, Installing Application, Create Documents –Maintenance Modified design, code and text

Object Technology

OBJECT 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 An ObjectWith MessagesInstance

UML

WHAT IS THE UML? A visual language for modeling and communicating about systems through the use of diagrams and supporting text The Three Aspects of UML –Language –Model –Unified 6 Counting Language Arithmetic Language

DIAGRAMS 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 UML 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
