Answer Posted / raju sharma

Hello Brother,

The ETL indicates Extract-->Transfer-->Load. You need to
know the data transaction between the source to target via
ETL . There are diffrent tools which are meant for ETL are
avialable in market like Abinitio,Informatic or like
Datastage etc. When in all the tool the common is
processing of data from source to target. You need to
understand the flow and mainly with the performance. Since
all the tools are measured based on thier performance of
loading the data. Beside to this you should also hold the
knowledge of Unix & DB. Becasuse the file level validation
requires unix more frequently.

Basic understanding of the ETL tool is enough for the
tester to proceed with thier test.Altogether an Tester can
become developer and in most companies they are preffered
too since tester have indepth knowldege of Functional part
as well the code.
