HI All,

I am newbie to this forum and also data modeling. I’v downlaod trial version and want to create a data model from scratch. I really don’t kno, how to start with ? I was wondering, if TOAD can do it for us and ifnot could you help me to locate a document, where I can learn data modeling and ER diagram from scratch. Your kind support would be highly appriciated.

Hi Alok,

good place for start is http://en.wikipedia.org/wiki/Data_modeling .Then you can read our Help and Manual in Toad Data Modeler,then watch our movies http://modeling.inside.quest.com/kbcategory.jspa?categoryID=116 and after that take a look at our sample model Videorental in Toad Data Modeler.

You can find platform specific questions on Windows,Linux/BSD/Unix and Apple pages,database specific questions on pages of Oracle,MySQL,PostgreSQL,MS SQL…

Here are some tips for good books about topic http://www.datamodel.org/DataModelLibrary.html

Toad Data Modeler does not have wizard for data modeling.You must design manually or you can reverse some sample database from your server and then make changes.
