Definition

Mediation is the process of reconciling differences to reach an agreement between different parties. In databases, the goal of mediation is to compute a common view over multiple, distinct, and heterogeneous sources of data. In software architecture, a component plays the role of mediator if it achieves interoperability by decoupling heterogeneous component having mismatching interfaces. Protocol mediation enables the exchange of information between autonomous endpoints that use incompatible communication protocols.

Mediation middleware helps applications deal with heterogeneity. By hiding the multiplicity and the complexity of the underlying systems, it transforms a one-to-many interaction (the application communicating with multiple data sources) into a simpler, one-to-one interaction (the application communicates with the mediator) and shifts the complexity of handling the communication with multiple, heterogeneous...
