Source model¶
This model describes an example source database that is used in the examples. The model contains two table definitions. The tables are wrapped in a collection named mappableObjects. For each table the column definitions are provided including datatype, nullability and primary key specification.
Note
Note that this is a model that only describes structure. All the information in this model could for example be obtained from querying a database's metadata tables.
