Life Cycle Model

This is known as Life Cycle Model.This has the following activites
• System Information/Engineering and Modeling
• Software Requirement Analysis
• System Analysis and Design
• Code Genaration
• Tesing
• Maintenance
System Information/Engineering and Modeling :
1.The intial propasal phase to understand and identify the project requirements and main features proposed in the application.
2. By the end of the study the entire client sytems, the team furnishes a document that holds specific recommendations for the condidate system. Out Put of this phase
• A rough estimation of efforts and prices for entire project.
• A Rough Shedule for entire phase
• Intial business functions in the project
System Rquirement Analysis & Specification :
The objective of this pahase to identify and document the user requirements for a proposed system.This phase contains complete information of function, information of the domin for thesoftware,behavior,performance,Interfacing.Out put of this phase is
• an estimate for effort or price for remaining project phases(Design, Development, Testing, Deployment, Support)
• Details Schedule of the remaining Phases(Design, Development, Testing, Deployment, Support)
• The final functional specification and analysis for other phases
System Analysi and Design:
This process of designing exactly of the specifications are to be implemented.
2. How the software to writen, including object modelwith properties and methods, Databse Designing,Cleint server architecture. Out put of this Phase
• A Final Design Specification

Code Genaration :
1. Design Must be Formated in to mechine readle format.
2. With respect of the application the right programming language is used,
• A Beta version of application
• Preliminary Manuals and userdocument
• Priliminary Technical Documents
Testing:
Once code is genarated Program testing begains.Diffrent testing methodlogies are available to unreval the bugs.Out put of this phage
• A Final version of complete application
• A Final Manual
• A Final Technical Document

Deployement & Maintenanace:
In This software ready to deploy in customer place, maintenance period starts for the application.Application should create accept the changes in this phase.
