I'd say having some sort of data modelling tool at your disposal is pretty much essential to understanding the table layouts and relationships for anything but the most trivial model. If you do any sort of data modeling or database design, or if you interface with developers, having a nice ERD is key.
Major ERD Tools out there: - S-Designer/PowerDesigner Data Architect - LogicWorks (now Platinum) ERwin - Cast db-builder - Embarcadero's ER/Studio - Microsoft Visio (now has an ERD module) Others that i'm not as familiar with: - DeZign - Silverrun's RDM - Rational Rose 2000E - Oracle Designer 2000 - Popkin's System Architect - Select Enterprise - RevSQL: http://www.sqlworkshop.com/ - Clear Case hope this helps. boss - > > > How essential the following tools to a DBAs job? > (viz) Rational Rose, Clear case for Versioning etc. What are Data > Modelling tools avbl. in the market and which are widely used > (other than Oracle Designer)?. > > > TIA > > > > _______________________________________________ > No banners.
