The data source being used determines the type of metadata
that is required. For example,
- When the server accesses
a relational data source, it needs to know how to interpret the
data stored there. You must create a synonym that describes the
structure of the data source and the server mapping of the data
types.
- When the server invokes
a transaction or procedure, it needs to know how to build the request,
what parameters to pass, and how to format an answer set from the
response. You must create a synonym that describes the layout of
the request/response area.
Whatever your data source, the adapter you are using manages
the synonym creation process for you, creating a synonym that meets
your specific requirements.
This topic describes briefly how to create, test, and otherwise
manage a synonym, using the Web Console or the Data Management Console.
