  • Patent number: 8095499
    Abstract: Queries to obtain data from an OLAP cube for a structured report are consolidated. Queries to retrieve data from an OLAP cube for a structured report are consolidated into a single query. Using the consolidated query reduces the number of database hits; avoids reconstruction of the report from the results of the individual queries; and eases the exporting of the report to other applications. Instead of querying the OLAP cube multiple times, a single query is used to obtain the desired information from the cube. Each access definition within the structured report is examined to determine all of the data to be retrieved from the OLAP cube.

  • Patent number: 7747939
    Abstract: Free form reports may be generated within a data array system such as a spreadsheet computer application. A user may select dimension members of a data source, such as an online analytical processing (OLAP) data cube. The user may position the dimension members as headers on the data array where multiple dimensions may be represented in one or both axes. Member formulas are generated that are representative of the headers and include identifiers that point to the dimension member location of the data source. Value formulas are generated within the report grid defined by the location of the headers where the value formulas are representative of the actual data values of the report and include identifiers that point to the data value locations of the dimension member locations within the data source.

  • Patent number: 7653637
    Abstract: Indirect persistent storage of data in a file that is associated with an application program and is capable of having an embedded OLEObject includes creating the OLEObject by way of a Component Object Model add-in that supplements the application program, and using the OLEObject to store the data in the file. The OLEObject is marked so that it is hidden from a user of the application program. After loading a file that was previously saved and closed, the OLEObject is initialized, and the stored data is retrieved. The add-in may be a reporting add-in that queries a database, such as an OLAP database.

  • Patent number: 7418460
    Abstract: A method and system provides reversibility of an operation performed by a user of an application program and associated with a modification to an object model of the application program, such as a spreadsheet program or other office productivity application program. The top item of a first undo stack associated with the application program is determined, saved, and copied to a second stack functioning as a replicated undo stack. According to one aspect of the invention, such steps are performed prior to calling an object model method that clears the first undo stack. The top item of the second replicated undo stack is placed back onto the first undo stack.
