    摘要: Provided are systems and methods that facilitate direct write back in a multi-dimensional database. The system includes a delta cache component that receives a user request to change an original cell value and determines a delta value based at least in part upon the changed cell value. Also included is a write back partition component that selectively updates a data cell based at least in part upon the delta value without updating corresponding data cell values. The system and methods allow attributes to be added to any dimension of a cube without affecting the write back data. Adding, modifying or removing a hierarchy has no affect on write back data nor does deleting a dimension that is not referenced by a write back.

    摘要: A system that facilitates generating a report based upon data within a relational database comprises a mapping component that utilizes mapping functions to associate a multi-dimensional structure with the relational database. A report generator communicates with the multi-dimensional structure to obtain data relating to the relational database and generates a report that includes the obtained data. For example, the mapping component can utilize measure groups to effectuate the association between the multi-dimensional structure and the relational database.

    摘要: Computer-readable media, systems, and methods for building a multidimensional data cube having one or more high-cardinality attributes are described. In embodiments, data is extracted from one or more databases. It is determined that one or more instances of the data are fact data and one or more instances of the data are dimension data. Each member of the fact data is one instance of a dimension and each instance of the dimension data includes an attribute for grouping the fact data. Moreover, in embodiments it is determined that one or more instances of the dimension data are high-cardinality attributes. The one or more high-cardinality attributes are processed with fact data and stored in fact tables on a computer storage medium.

    摘要: Systems, clients, servers, methods, and computer-readable media of varying scope are described in which, a database client applies an adaptive method to dynamically determines whether a particular request should execute on the client-side or the server-side of a client-server database system. In determining where a particular request should be executed, the database client analyzes the size of the data sets involved and the data flow generated by the data sets.
