[edit] Remark

Please keep to information that is understandable by common readers. Do not use ambiguous in-house definitions of general terms like data warehouse -- this is generally denoted as an application of a DBMS, whereas someone editing this page used it in the sense of a DBMS.

What is shared nothing architecture? Define it or I will remove the sentence.

[edit] Wal-Mart?

Actually, Wal-Mart was not Teradata's first customer. Wal-Mart bought its first Teradata system in 1989, by which time Teradata was already being used by more than 100 enterprises.

K-Mart and AT&T were among the early adopters.

Lot of companies now using Teradata for Active data warehousing.

Folks, Remove Unica from the teradata link, as it is misleading.

[edit] Customers

Teradata has many customers; however, it isn't necessary to add all of them to this article. Eight well known customers plus the Wal-Mart mention is enough. Stephenpace 22:53, 27 February 2007 (UTC)

[edit] SAP Partnership

To be clear on this partnership, at the time the agreement was announced it essentially allowed SAP BW customers to load data from Teradata sources, but did not allow data from SAP BW to flow back to Teradata. Stephenpace 16:52, 6 February 2007 (UTC) This is clearly not true. To allow users to access the data in a more timely fashion, Teradata can be used (in conjunction with Oracle) as the DBMS for SAP BW, while SAP Open Hub Data Extract from SAP BW to Teradata allows data to flow from SAP BW into Teradata. --Jeffpankow 16:31, 30 March 2007 (UTC) You are probably much more up on this than me, so I amended my text to reflect that at the time of the announcement, it was essentially a one-way agreement. No doubt things have moved on a bit. One thing I would say is that from an outsider point of view, SAP appeared to get a lot more out of this than Teradata did. Anything short of a native port of SAP BW to Teradata (not a kludge of having to go through a non-Teradata RDBMS like Oracle) seems like a net loss for Teradata, especially since SAP is beginning to shift focus to their own BI appliance to address performance issues in another way. Also, when BW first arrived on the scene, I heard that some SAP customers were prevented by contract from wholesale moving SAP BW data to other platforms, although I've also heard some customers pushed back on that requirement so it may not be as much of an issue anymore, especially if products like SAP Open Hub Data Extract now exist and work as designed. Even then, though, having and moving data around between multiple data warehouses seems to defeat the purpose somewhat of having 'one version of the truth'. I'd rather have one Teradata warehouse (or if forced to, one SAP BW) so I didn't have to maintain two copies. Stephenpace 17:28, 30 March 2007 (UTC) As I see it, the idea of the SAP product (and Teradata for that matter) is to deliver value to the end user. It may be a bit of a kludge, but this is a way to augment a base architecture that cannot handle the desired workload. The majority of SAP customers do not require the additional power, and it is probably easier and more adventageous to SAP to divert work than it is to modify their base architecture.--Jeffpankow 21:32, 30 March 2007 (UTC)

[edit] Competition

Teradata has competition on a number of fronts, and this section needs expanding. While they pioneered this market, Teradata's historically high pricing opened the door for smaller data warehouse appliance vendors like Netezza, DATAllegro, and Calpont. On the packaged data warehouse front, software products like SAP BW and Kalido have won business and have been a primary blocker for Teradata moving into the energy vertical. And their primary competition is still custom built warehousing using other high-end database technology from IBM and Oracle. Please do not remove any one of these three areas without further discussion. Thanks. Stephenpace 16:52, 6 February 2007 (UTC) Teradata does have competition on a variety of fronts. Some of this is due to the data warehouse expansion into businesses that would not have dreamed there to be a need just a few years ago. It also has to do with Teradata being in the business of more than just Enterprise Data Warehousing (CRM and DCM in particular). My removal of SAP and Kalido previously was rooted in the fact that I have seen this particular section used as a way for companies (that had apsirations to compete in the EDW space) promote their product (aka advertising). Being that I do not believe that these two products (or Calpont) are actually competing in the same space that Teradata actually competes in, I felt it was prudent for me to delete them from the section. People traditionally buy SAP for reasons other than their BW (thus I do not see it as competition), and Kalido is a company I have never heard of (as is also the case with Calpont). Being in Houston, you probably see more of the energy sector than I do (I have traditionally operated in the retail and travel sectors) so I will give you the benefit of the doubt. --Jeffpankow 21:53, 30 March 2007 (UTC)

No need to list every data appliance vendor. Netezza and DataAllegro are the most prominent. Greenplum seems to have some endorsement by Sun and PANTA seems to have some endorsement by Oracle, but neither seems to have made a market impact yet. Removed for now. Stephenpace 12:15, 5 July 2007 (UTC) I reverted the appliance vendor section again. How many is the correct number? I don't know, but I think a good indicator is revenue by product line. Any vendor with revenue under $10 million per year is hardly competition for Teradata, IMHO. I would think that HP Neoview is likely to be a viable competitor in the future especially given their backing, but to date I haven't seen much about their customer successes yet.

[edit] Advertising

This page reads like an advert. Tagging advertising. Saganaki- 04:42, 5 February 2007 (UTC)

No more so than similar pages on IBM and Oracle, and they aren't tagged. Duncan 17:02, 14 February 2007 (UTC)

Feel free to tag other articles you feel don't meet article standards. Stephenpace 22:53, 27 February 2007 (UTC)

[edit] How come no information on AT&Ts ownership?

The original AT&T owned NCR for a few disatrous years and I understand the whole Teradata product line was almost killed off. It is my understanding that it wasn't until NCR itself was spun off and needed something to sell that Teradata as a product actually took off. I don't have enough detailed understanding to make changes to the entry as such. But it is quite a story! surely someone with some detailed knowledge could add something.

[edit] Need more on their DBMS

Is their DBMS proprietary or is it add-ons atop another DBMS? Is it relational? Is it ANSI SQL compliant? Does it come with procedural language interface, etc.

cheers,

Teradata has their own relational database (e.g. it is not Oracle or DB2 under the covers). Regarding ANSI SQL compliance, from what I understand, Teradata implements a very large subset of the SQL 2003 core language standard, similar to other database vendors.
