Multiple databases an EOModel.

Hi list,

We are developing an ERP application.
We want to use the following approach:

One database to storage users, access control rules, application configuration and an enterprises catalog.

For each enterprise we want to set up a different database. 

For example: One ERP controlling information of two enterprises would need three databases:
  • ApplicationDatabase
  • EnterpriseOneDatabase
  • EnterpriseTwoDatabase

We are doing this because we believe this is more efficient in the long term with clients that have more than one enterprise.

We have two Data base Models in the application

  • ErpApplicatioEOModel
  • ErpEnterpriseEOModel

The main page is a Login form where the user selects the Enterprise she wants to work with. After the user logins successfully we want to set the database connection information in the ErpEnterpriseEOModel.

Is that possible?


Thanks in advanced.

Saludos, Miguel Torres.
