Data storage schema independent programming for data retrieval using semantic bridge

摘要

A computer implemented process accesses data stored on one or more computers, the data on each computer having a data storage schema. A program is generated to access the data using terms and constructs of a semantic programming interface. The semantic programming interface provides an abstract, object-oriented representation of the data that is independent of the data storage schemas of the data. Mappings of the representation of the data in the semantic programming interface to each of the data storage schemas of the data stored on the one or more computers are created. The data mappings are used to translate the interface-based program into one or more executable programs. The executable programs are run to access the data stored on the one or more computers. System security and data security are maintained on the one or more computers.
