Data spaces for multi-tenant computing

A multi-tenancy data processing system adapted for data access, the system comprising:

• a host computing platform comprising one or more computers, each comprising memory and at least one processor;
• different application networks deployed into a multi-tenancy computing environment established in the host computing platform, each of the networks providing program logic of one or more application instances and also supporting exchanges of messages between ones of the different end users within a same one of the networks;
• and,
• a data access module comprising computer program instructions enabled while executing in the host computing platform to perform:
• defining for each of the networks, a separate data space within the multi-tenancy computing system, each said separate data space comprising an interface to one or more data repositories and providing a virtual data access layer between a corresponding one of the different application networks and data in the data storage infrastructure, irrespective of actual physical data storage resource or resources present in the data storage infrastructure storing data accessible by the different end users of corresponding ones of the application networks;
• and,
• processing data queries by ones of the different end users by extracting meta-data from each of the queries and filtering corresponding underlying data queries to the data repositories with a key derived from the extracted meta-data.

A computer program product for data access method for a multi-tenancy environment, the computer program product including a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method including:

• deploying into a multi-tenancy computing system, different application networks in which different end users of different ones of the networks access therein common program logic of one or more application instances and also exchange messages between ones of the different end users within a same one of the networks;
• defining for each of the networks, a separate data space within the multi-tenancy computing system, each said separate data space comprising an interface to one or more data repositories and providing a virtual data access layer between a corresponding one of the different application networks and data in the data storage infrastructure, irrespective of actual physical data storage resource or resources present in the data storage infrastructure storing data accessible by the different end users of corresponding ones of the application networks;
• and,
• processing data queries by ones of the different end users by extracting meta-data from each of the queries and filtering corresponding underlying data queries to the data repositories with a key derived from the extracted meta-data.
