Definition

Information integration systems offer uniform access to a set of autonomous and heterogeneous data sources. Sources can range from database systems and legacy systems to forms on the Web, web services and flat files. The data in the sources need not be completely structured as in relational databases. The number of sources in an information integration application can range from a handful to thousands.

Historical Background

Database applications are typically heavily designed and tuned for a specific context. But as data management needs in enterprises change and the information economy evolves, the need to combine information from multiple sources arises frequently. Examples of such scenarios include mergers and acquisitions, internal restructuring, the need to interoperate with third parties and to expose data on the web. Since the early 1980s the need to combine multiple heterogeneous data sources has become a...
