* SOA ([[Service-Oriented Architecture]]) implementations
Core data integrations are often designed with to be enterprise-wide integration solutions. They may be designed to provide a data abstraction layer, which in turn will be used by individual core data integration implementations, such as ETL servers or applications integrated through EAI.
A core data integration differs from an edge data integration, which is not centrally planned and which will probably be completed with a smaller budget and a tighter deadline. Most edge integrations involve hand-coded scripts. Some may take the form of enterprise mashups, [[Rich Internet applications]], or other browser-based models that take advantage of [[Web 2.0]] technologies to combine data in a Web browser.
