explain sdlc?..

Answer / sunithayagnamurthy

explain SDLC:
SDLc are 5 stages
1.Analysis phase
2.Design phase
3.coading
4.testing
5.release & maintaince
Analysis phase: In my opinion analysis phase is most
Importent in every ptoduct .
At the analysis phase stage the customer
will analyse:
1.need of the project
2.cost of the project
3.what are the benfits and advantages of
the project
4.Identify the requirment
5.Identify the scope of the project
6.agrement with any development company to
develop the software
Note: At this stage the development company also analyse
the cost of the project resource required,technolagy to
develop the s/w and get the agrement with development
company
The fallowing documents sre prepared at this
stage
1.NDA (NON disclosive agreement):
It should fallow some rulles and
regulations
2.SLA(service Level agreement).This
document contaains the services to be provided by the
development company to this customer
3.BRS (buisiness requirment specification):
This document contain overall
functional details about the s/w
NDA,SLA are prepared by managers of
development company and customer company,approved by both
company
BRS document prepared by Buisiness analyst
4.Project plan:
This document has the overall shedules of
the project,cost,resources etc.It is prepared by project
manager
5.FRS/FRD:(Functional Requirment specification or document)

This document about detailed information about all the
requirments.This document prepared by buisiness analyst.

6.Software requirment specification:
It contains Software requirment
details like front end technolagy,backend
technolagy,operating systems,Hardware architecture of the
project are described
And then go to design phase
After analysis the development will prepare the design
phase for the project
the design is prepared as per requrment.The
design for frontend based on the HLD ,LLd,Dtabasedesign.

HLD means (High level design):
It explain main modules of the project
LLD means (Low lwvwl design):
It explain all the details of the operands etc

and then goto coading:

After design approved the development team will design the
code and write the code.

and then goto testing:
After coading is done the application is
tested to ensure it is working as per the requirment .
testing is conducted by developers,testing
team,users at different stages
and then goto Realease & Maintaince::

After testing is completed the s/w is released to the
cusomer,After released maintaince is the for any issues in
the s/w.
:This is the s/w Development Life Cycle:

Answer / guest

there are 5 phases in sdlc:
1)requirement & analysis
2)design
3)coding
4)testing
5)maintainance

1)requirement & analysis:
the main aim of requirement analysis phase is to produce
a document that properly specifies all reuirements of the
customer.
requirement specification document is the primary out put
of this phase.
proper requirements and analysys are critical for having
succesful project.
the need for executing this phase properly to produce an
srs with the least defect should be evident.

2)design: during the design phase the user requirements are
elicited and software satisfying these requirements are
designed built tested,delivered to the customer.

high level:high level design is the phase of life cycle
the logical view of computer implementation of solution to
the customer requirements are developed.it gives the
solution at high level of abstraction.during the high level
design the functional architecture of application and
database design takes place.
the entry criteria is that srs has been reviewed and
authourised. the input for this phase is software
requirement specification and output for this phase is high
level design document. the exit criteria is that the high
level design document has been reviewed and authourised.

low level design:the view of the application developed in
the high level design is broken into modules and logic
design is done for every program .a unit test plan is
created and documented as program specification. the
important activity in the detailed design phase is
identification of common routines and programs.

the entry criteria is that the highlevel design document
has been reviewed and authourised.
the exit criteria is that the program specification
document has been reviewed and authourised.

coding:
during the coding phase required programing language is
used to produce the program.this phase produces source
code, executables and database design.

testing:
here actual testing takes place .

maintainance:
succesfully developed project will undergo for maintainance.
