Home -> Community -> Mailing Lists -> Oracle-L -> RE: What tools for Oracle Data Warehouse ETL
I'm most familiar with DataStage, as I took the training for that tool.
It uses it's own version if a VB like language for building jobs. It also allows you to run external programs and scripts as part of a job.
It was very powerful and flexible, not too hard to use either, a rare combination of traits.
Someone else mentioned Ab Inito (sp?) in another post, but I have no knowledge of that tool.

Subject: RE: What tools for Oracle Data Warehouse ETL
Thanks Jared for your invaluable information.
One more question,
To my very little knowledge about these tools(DataStage, Informatica),
do these tools generate Oracle executable scripts for ETL process? To my
knowledge, OWBuilder(Oracle Warehouse Builder) is a good one for me at
this moment in the sense of its 100% compatibile with Oracle. But I
cannot get evaluation on "to what extents to use it to create ETL".
Maybe somewhere outside, such as Quest product, got such a kind of
tool.

In the second half of 2000, I participated in an extensive evaluation of ETL tools for a large data warehouse.
There were two main players at that time that we considered:
DataStage, owned by Informix, and now part of Ascential software http://www.ascentialsoftware.com/products/datastage/
Informatica was the other.
http://www.informatica.com/
We looked at some other tools, notably IBM's offerings and one other that I can't recall. They didn't make it to the hands on evaluation stage for a number of reasons.
Informatica and DataStage both appeared to be excellent tools. Informatica clearly had a better interface, while DataStage had a top down methodology that we preferred.
The strength of these tools IMO is that they allow a team to effectively organize and manage the ETL process and all of the code that goes with it.
You can do the same thing without these tools, but it will more difficult to manage.
Tom Cox may have something to add to this, as he was leading that evaluation.
Tom?

Subject: What tools for Oracle Data Warehouse ETL
Hi, DBA gurus,
I am going to build our data warehousing project. In theory, I am confident but in reality, .... At this moment, I only have Oracle Data Warehousing Builder 3i in my hand. For those have built DW in Oracle, could you share your experience on the tools to build the data warehousing especially ETL process?
Many thanks in advance,
Chuan
