   The integration system must execute a search over the space of possible queries in order to find the best rewrite. The resulting rewrite may not be an equivalent query but maximally contained, and the resulting tuples may be incomplete. As of 2011 the GQR algorithm [22] is the leading query rewriting algorithm for LAV data integration systems.

3. System integration - Wikipedia

   en.wikipedia.org/wiki/System_integration

   System integration is defined in engineering as the process of bringing together the component sub-systems into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, [1] and in information technology [2] as the process of linking together different computing ...

4. Data mapping - Wikipedia

   en.wikipedia.org/wiki/Data_mapping

   In computing and data management, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks, including: [1] Data transformation or data mediation between a data source and a destination

5. Data architecture - Wikipedia

   en.wikipedia.org/wiki/Data_architecture

   Data integration, for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems. A data architecture, in part, describes the data structures used by a business and its computer applications software .

6. Enterprise application integration - Wikipedia

   EAI systems implement two patterns: [4] Mediation (intra-communication) Here, the EAI system acts as the go-between or broker between multiple applications. Whenever an interesting event occurs in an application (for instance, new information is created or a new transaction completed) an integration module in the EAI system is notified.

7. Interoperability - Wikipedia

   Low-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the communicating systems. Beyond the ability of two or more computer systems to exchange information, semantic interoperability is the ability to automatically interpret the ...
