) implementations Core data integrations are often designed 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. Because it is difficult to promptly roll out a centrally managed data integration solution that anticipates and meets all data integration requirements across an organization, IT engineers and even business users create

edge data integration An edge data integration is an implementation of data integration technology undertaken in an ad hoc or tactical fashion. This is also sometimes referred to as point-to-point integration because it connects two types of data directly to serve a nar ...
