SOFTWARE DEVELOPMENT LIFE CYCLE

OTHER TERM FOR SOFTWARE DEVELOPMENT

SDLC

s an integral part of software development process knowledge and followed by developers AND also helps in reducing the time for software development

PLANNING, ANALYSIS, DESIGN, IMPLEMENTATION, TESTING, AND DEVELOPMENT AND MAINTENANCE

WHAT ARE THE SIX PHASES OF SDLC?

PLANNING

. In this phase, the information needed are identified, gathered and examined.

ANALYSIS

In this phase special tools help the analyst make requirement determinations. Diagrams are being created in this phase such as Class Diagram, USE CASE, Activity Diagram, etc.

ANALYSIS

During —- the analyst studies the organization´s current procedures and the information systems used to perform organizational tasks.

DESIGN

In this phase of SDLC analyst uses the information collected earlier to accomplish the logical design of the information system AND ALSO In this phase analyst also works with users to design output that meets their information needs.

INTERFACE

connects the user with the system and is thus extremly important.

DESIGN

This phase also includes designing files or databases that will store much of the data needed by decision makers in the organization

HIGH LEVEL DESIGN AND LOW LEVEL DESIGN

HLD AND LLD MEANING

IMPLEMENTATION

In this phase, developers start build the entire system by writing code using the chosen programming language

IMPLEMENTATION

In this phase, Developer needs to follow certain predefined coding guidelines. They also need to use programming tools like compiler, interpreters, debugger to generate and implement the code.

TESTING

. A series of tests to pinpoint problems is run first with sample data and eventually with actual data from the current system

DEVELOPMENT AND MAINTENANCE

This is the last phase of system development. The analyst helps to implement the information system. This phase involves training the users to handle the system.
