IBM’s data integration products provide three methods for delivering data: ETL (extract, transform and load), which provides bulk (batch) data loading functionality; data federation, which supports virtual data delivery; and data replication, which allows incremental updates.
The use of ETL processes has been well-established for the best part of twenty years and it is well understood. As a result we will not be discussing this aspect of IBM’s portfolio. However, both replication and federation are becoming increasingly popular and relevant, and in this paper we will discuss why that is the case as well as IBM’s offerings in this area.
