What are some of the approaches to data integration?
What will be an ideal response?
Data integration creates a unified view of business data. There are three approaches to data integration. The first approach, which is widely used in data warehousing, is consolidation. In this approach, data are loaded and transformed into a dataset useful for reporting or decision support. Another approach, data federation, provides a virtual view of integrated data without actually bringing the data into one database. The third approach, data propagation, duplicates data across databases.
