Project Explanation:
I’m giving generic explanation of the project. Any project
either banking or sales or
insurance can use this explanation.
First u have to start with
1) U have to first explain about objective of the project
and what is client
2) u have to start where ur involvement and responsibility
of ur job and limitations
of job.
Add some points from post Project Architecture reply like
offshore and onsite model
and team structure.. etc.,
Main objective of this project is we are providing a system
with all the information
regarding Sales / Transactions (sales if sales domain /
transactions if bank domain or
insurance domain) of entire organizations all over the
country US / UK ( based on the
client location US/UK/…..). we will get the daily
transaction data from all branches at
the end of the day. We have to validate the transactions and
implement the business logic
based on the transactions type or transaction code. We have
to load all historical data into
dwh and once finished historical data. We have to load Delta
Loads. Delta load means
last 24 hrs transactions captured from the source system. In
other words u can call it as
Change Data Capture (CDC). This Delta loads are scheduled
daily basis. Pick some
points from What is Target Staging Area Post.. Source to
Staging mappings, staging to
warehousing.. based on ur comfort level..
Each transaction contains Transaction code.. based on the
transaction code u can identify
wheather that transaction belongs to sales, purchase / car
insurance, health insurance, /
deposit , loan, payment ( u have to change the words based
on the project..) etc., based on
that code business logic will be change.. we validate and
calculate the measure and load to database.
One Mapping explanation :
In Informatica mapping, we first lookup all the transaction
codes with code master table
to identify the transaction type to implement the correct
logic and filter the unnecessary
transactions.. because in an organization there are lot of
transactions will be there but u
have to consider only required transactions for ur project..
the transaction code exists in
the code master table are only transactions u have to
consider and other transactions load
into one table called Wrap table and invalid records (
transaction code missing, null,
spaces) to error table. For each dimension table we are
creating surrogate key and load
into DWH tables.
SCD2 Mapping:
We are implementing SCD2 mapping for customer dimension or
account dimension to
keep history of the accounts or customers. We are using SCD2
Date method.
before telling
this u should know it clearly abt this SCD2 method..careful
abt it..
Pick from Project architecture Post and tell according ur
level.. we are responsible for only development and testing
and scheduling we are using
third party tools..( Control M, AutoSys, Job Tracker, Tivoli
or etc..) we simply give the
dependencies between each mapping and run time. Based on
that Information scheduling
tool team will schedule the mappings. We won’t schedule in
Informatica .. that’s it
Please Let me know if u required more explanation regarding
any point reply ……

im explained earliarly as follows,

im working under insurence domain project, usually i
extract the data from defferent sources like flat files,
oracle, db2.

first we load the extracted data into intermidiate staging
area, where we are having 150 tables, and again we extract
data from intermediate staging area and we load into an
other staging area where we are having event and value base

we transfom the data into staging according to the business
requirement , to transform the data i used trasformations
like expression, lookup,update strategy,joiner wtc
