How to use the business mapper?

After adding a Business object to the project I go into the Object mapper.

The first time it asks you to configure the project. You give it a name, and select SQL server.

The system we are testing with is using sql express on (local)\sqlexpress and the database name is TRAC.

Do you have to enter a connection string and if so what is the format?

The connection string is that which is required to connect to the server... not necessarily the database.



So, your connection string would be something like "Server=localhost\sqlexpress;Integrated Security=SSPI;" if you're using Windows authentication or "Server=localhost\sqlexpress;User Id=sa;Password=MyPassword;" if you're using username authentication.



The connection string is required so that the Business Object Mapper can gather the schema information from the server.

I guess it doesn't use the previous connection string information you entered?

Nope, it saves the connection string information on a per-project basis. But, yes, it would be a good idea to carry forward the last entered connection string. I'll look into that.
