A method and system are provided for running an application system to provide client access through one or more applications to data stored in a heterogeneous data storage environment. The method involves uploading selected data from the heterogeneous data storage environment, which comprises multiple separate database systems, into the application system. The uploaded data is saved in the application system in a homogeneous data storage environment, which has a structure that reflects the applications themselves. Requests are received from clients to access the saved data. Each request identifies one of the applications. A received request is forwarded to the identified application, which accesses the saved data in order to generate a reply to the request. This reply can now be returned from the application system to the client as a response to the request. |
