Developing a Metadata Model
Create or import a metadata model that you can use to specify the schema for a new view model, validate the schema of a data service, database operation, or table, or establish an alias you can use to call a
data service, database operation, or table.
- Metadata Models
In Sybase Data Federation, a metadata model expresses a schema. Each metadata model defines a set of tables; each table contains a set of named columns and each column is associated with a data type.
- Importing a Metadata Model
You can import several kinds of data model (schema) files into WorkSpace Data Federation.
- Creating a Metadata Model
You can create a new metadata model using WorkSpace Data Federation.
- Editing a Metadata Model
Editing metadata models is simpler than editing view models because there is only one type of element in the model—a table. There are no connections between tables. Every table has a name and zero or more column definitions.
- Deriving a View Model from a Metadata Model
Deriving a view model from a metadata model is a way to create a new view model (and eventually a new data service) with a designated output schema.
- Mapping a Metadata Model to a Grid Object
You can map (link) a table in a metadata model to a Data Federation object, such as a data service or a database operation, or to a table in a database. You can use mapping for both schema validation and aliasing.
- Deleting a Metadata Model
Undeploy metadata models rather than deleting them through the data catalog.
