You can use the New Extract Service wizard to create a distributed extract service.
An extract service copies a set of related rows from one or more tables and stores this data in an extract file. The extract service always includes the definitions for tables and columns. You can also choose to extract object definitions, including primary keys, relationships, and indexes. An extract service request specifies an access definition to define the data to extract and the parameters needed to run the extract process.
A extract service requires an Optim™ logical data model to provide the source data.
