Re: Oracle Warehousing or Teradata

Hi,

I don't have any real experience with Teradata, however I know of some very high profile datawarehousing project which have used it. Typically you are talking about seriously large datawarehousing sites... Telco's keeping CDRs (Call Detail Records), Walmart tracking the sale of every item nation wide.

They have an interesting architecture and I suspect the theory goes along the lines of "Oracle has elegance (bitmaps, partitioning, mat views) whilst Teradata has brunt (thousands of cheap PC's working as one).

Of course my best recommendation is to ignore everything I said and invite the Teradata folk in for a presentation. If the sales manager can smell a potential licence they'll come and visit you for free. Naturally you could also invite Oracle to come talk about the differences between Oracle and Teradata. Heck, have some fun and invite them to each others presentations (I've never seen it done, but it could be quite funny).

I took a fairly close look at Teradata 2.5 years ago.

At that time, I could not see where it had any advantage over Oracle, particularly for Data Warehousing using star schemas.

Whereas there are many benefits to using Oracle.

Bitmap indexes ( don't think TD had those)

Partitioning - TD had something like it, but the Oracle version was much more robust IIRC.

Availability of skilled personnel - At the time I checked, there were 69 open TD positions nationwide - At that time there were 6900 Oracle positions.

Non-proprietary - Teradata runs on NT or NCR, nothing else.

Expense - believe it or not, TD costs more than Oracle.

Development tools and 3rd party software - much more support for Oracle.

... more I can't recall.

My employer at that time decided to dump Oracle for DW and go with TD instead. I left.

        Subject:        Oracle Warehousing or Teradata

One of our clients was interested in knowing which warehousing software he should consider. Since he is already using Oracle, so he wanted to know about the Oracle warehousing capabilities, as compared to Teradata. So also for the sake of knowledge, which one is better and if one could be a replacement of the other, in any environment. Regards,
Hussain
