Providing homogeneous views of information collections in heterogeneous information storage sources

A framework for supporting a homogeneous view of an information collection managed in a heterogeneous computer system of information storage sources, comprising:

• an information collection data model defining information to be collected and stored as an information collection in one or more information storage sources;
• an information source data model referencing data sets containing the information defined in the information collection data model;
• a first mapping between the information collection data model and the information source data model;
• an information storage services data model defining information storage services for accessing and performing operations on the one or more information storage sources storing the information collection;
• and
• a second mapping between the information source data model and the information storage services data model,
• wherein the information collection data model, the information source data model, the information storage services data model, and the first and second mappings are configured to allow a user of the framework to view and perform operations on the information collection without having any knowledge about how the information collection is stored in the information storage sources.

A computer program product for supporting a homogeneous view of an information collection managed in a heterogeneous system of information storage sources, comprising, the computer program product comprising:

• a computer usable storage medium having computer usable program code embodied therewith, the computer usable program code comprising:
• computer usable program code configured to provide an information collection data model defining information to be collected and stored as an information collection in one or more information storage sources;
• computer usable program code configured to provide an information source data model referencing data sets containing the information defined in the information collection data model;
• computer usable program code configured to provide an information storage services data model defining information storage services for accessing and performing operations on the one or more information storage sources storing the information collection;
• computer usable program code configured to generate a first mapping between the information collection data model and the information source data model;
• and
• computer usable program code configured to generate second mapping between the information source data model and the information storage services data model,
• wherein the information collection data model, the information source data model, the information storage services data model, and the first and second mappings are configured to allow a user of the framework to view and perform operations on the information collection without having any knowledge about how the information collection is stored in the information storage sources.
