Answer

Well, this question is not specific to Datawarehouse. In
general these are the practises followed in software firms
while going ahead with any new project. Lets hover around
each topic asked

SRS (Software requirement Specification) : This is the
initial phase where customer specifies its requirements to
a software team. Actually its a study of what the customer
is asking for. It captures all details of issues faced by
customer and what are the projected solutions.

HLD (High Level Design) : This is next phase of design
where the inputs given from SRS are collected and
transformed into development methodolgy. It lays down the
roadmap of code development before actually jumping onto
the development.

LLD ( Low Level Design) : This is a actually a design
document. It gives all code details, all issue pertaining
to development. Its development tools, how to resolve
issues based on the given platform, so on so forth.

Code Review : This is the final phase of development where
developer is been rewarded for all his hard work and its
solution. Usually Managers, Sr. Developer, Product Managers
all sit together, get the feel of product and try to figure
out any loopholes. If any, developers are been asked to
revisit the code or else product is ready for QA team to
test and certify.
