Activating the data store. Before attempting to read or write any business objects, you must activate the appropriate data store. This is done by sending #activate to the singleton of your data store class. This will associate the appropriate service classes to the home collections, and initialize any required database connections. A sample data store activation would be similar to the following:
yourBusObjDataStore singleton activate
When testing your code, you can also activate a data store using the Status Tool.
