represent the metadata of the data source and the associated operations to read from and write to the data source.
Informatica Connector Toolkit
to define the following metadata components:
Define one or more native metadata objects to represent the metadata of the native source. Associate the native metadata objects with operations to read metadata from a data source, look up metadata from a data source, or write metadata to a data source.
You can define record extensions to define additional metadata for records. For example, you can add the attribute query hint as a record extension.
You can define field extensions to define additional metadata for fields. For example, you can add the attribute isNullable as a field extension to indicate that the field can contain a null value.
Define attributes that you can read from the data source. You can also define whether the adapter supports look up of data, join operations, and filter operations when the adapter reads from the data source.
Define attributes that you can write to the data source.
