We currently use Datastage ETL to – Export a CSV/text file with data from 15 tables(3 different schemas) on a daily basis.
I am wondering If there is a simpler way to accomplish this with out using an ETL. I tried Scriptella. It looks simple/fast, but it again it is an ETL. Please suggest..
We use Python. Every programming language — every single one ever invented — is an alternative to an ETL.
You never need an ETL.
The questions is these:
Which is cheaper to build? Custom software or a configuration of an ETL?
Which is cheaper to maintain an operate?
Which is easier to adapt to changing requirements?
