You can create a 
Database Resource from any 
Table in a 
Form that is not already backed by a Resource.
Open the New Resource Wizard by right-clicking on the Table in the Tables View of the Form's Editor and selecting 
Create Resource
.
On the first page of the Wizard, you can specify the name of the new Database Resource and where you want it to be added to the Workspace.
On the next Page of the Wizard, select the Database Connection to use to connect to the database and provide the name of the table to connect the Form's Table to.
Then, choose the 
Table Columns to be added to the Resource.
Finally, select one or more Table Columns that uniquely identify each row in the table.
Clicking Finish creates the Database Connection at the location specified at the start of the Wizard and adds it to the 
Resources View of the Form.
