Scripting on top of an Entity(not on the Form) in Dynamics CRM.

Hello!

I was wondering if I can replicate my database table in CRM...

In a correct sense, can I write script to call a Webservice on my Custom Module(eg: Rates) or System Module(Eg:Sales,Services,etc) to pull a database table with records and display the records as table format on an Entity.

In an other sense, I wish to show my database table with records in CRM. I know that we can import data and display the records on an entity. But is there a way to write code (calling a Webservice) on top of an Entity(instead of calling inside the form on some form events) ?

Any suggestions would be a great help!

Thanks,

Manu.
