Data source support for federated features
Refer to this table when you want to know whether or not a data source supports a specific federated feature.
Data source options
Which options you can specify when creating or altering a wrapper, server, user mapping, or nickname depends on the type of the data source.
Views in the global catalog table containing federated information
Most of the catalog views in a federated database are the same as the catalog views in any other Db2® database.
Function mapping options for federated systems
The federated server provides default mappings between Db2 functions and data source functions. For most data sources, the default function mappings are in the wrappers. To use a data source function that the federated server does not recognize or to change the default mapping, you create a function mapping.
Valid server types in SQL statements
Server types indicate the kind of data source that the server definition represents.
Data type mappings
Data types mappings for relational data sources include forward type mappings, reverse type mappings, and type mappings that are specific to Unicode. Each of the non-relational data sources support specific data types.
