ABSTRACT:
Techniques for replicating data in a system having a data tier with a plurality of data sources and an application tier with a plurality of applications are provided. Such techniques can include creating an instance of an information model of the data that is specified by a schema. The model can be created in a form that is suitable for manipulation by at least one of the applications and that forms at least a portion of a model tier that is intermediate the data tier and the application tier. A replica of an instance of the information model can be created in a form suitable for remote transmission, and a consistency policy can be obtained that specifies a level of consistency required between the instance of the information model and the replica.
