Home -> Community -> Mailing Lists -> Oracle-L -> Re: Data Modelling Tools for a DBAs Job
I guess "how important" depends on what type of DBA role you are filling. If it's a "system" type DBA role where your only real task is to keep the database running and perform some basic backup / recovery type work then understanding the intricacies of table relationships isn't very important.
If your role includes understanding table relationships, perhaps supporting development of the application sitting on the database, perhaps generating reports from the data, helping users write ad-hoc queries, etc then a good data modelling tool becomes essential... Unless of course there is already a data architect performing this role for you!
Where I am currently the tool of choice is Rational Rose. This was chosen largely because the application is OO based and Rational is a very good OO modelling tool. In my opinion though the data modelling side of the product leaves a lot to be desired. A couple of examples: The product cannot define a foreign key on an existing column without using a semi-official plugin. The product cannot reverse engineer UNIQUE indexes from Oracle 8i databases. These are both what I would consider fundamental requirements of a data modelling tool. In defence we are using version 2002 on an NT platform - perhaps things are better in the latest release. The last person to work on our model then brought the data across to Visio to produce a much cleaner diagram but I have no idea if this was a trivial or complex exercise.
Previously I had used ERwin and my memories of it are much better although I believe it's not the cheapest data modelling tool in existence. I think even the latest version of TOAD can build data model diagrams.
Regards,
Mark.
