Answer Posted / bharani
IF I were u wll expalin my proj like this
I working for ....(name of the proj) proj,client is ....
(name of the client), which is saless and distribution
domain, technology in my proj is .......(like Informatica
as ETL TOOL, BI TOOL AS COGNOS, Backend database is ORacle)
describe a bit about ur client business a bit.
( suppose for a mall inventory level, itemsold per week and
pregressive businessd timings like festivals)
as a report author i developed ..... these kind of
reports , which are very useful for enduser to take
business decisions.
Generally DWH group contains
1.database team( like oracle)
2.ETL team
3.BI team
4Testing Team
5.Support Team
team 1: perople generally load the data into database and
architect will prepare ER model for that and constraints
ofthe table.
Team2: once data entered into the dbase, Etl architect
prepares star schema for Dwh and Etl developers extract
data from dbase and made some transformations (depend on
business requirements like scrubbing) and load that data
into Datawarehouse in the form of datamarts.
Team3. Bi architect extract the data from Dwh and prepares
a model (universe)and work wll be assigned to Report author
to populate the data in the form of the reports asd per end
user requirement.
Team 4: testing team generally test the report and if any
bugs found dt will be forwarded to support team.
Team 5. this team people try to resolve those issues if it
is not possible for them again it wll transformed to Etl
team.
completely this is a cyclic process.
As of my knowledge.
