An application program interface (API) for a data platform. The API
includes a generic data access component that exposes at least one of
stores, sessions, transactions, and query services of the data platform,
which data platform is associated with a data store. A data classes
component of the API provides canonical, application-independent classes
that expose types and relationships of a data model of the data platform.
The API includes a domain data classes component of application-specific
and framework-specific classes that expose domain-specific properties and
behaviors of the data platform. The data platform can be a common data
platform that interfaces to the data store to provide data services
accessible by a plurality of disparate application frameworks, which data
services allow a corresponding application of the different frameworks to
access the data store.
