  • Multi-dimensional restructure performance by selecting a technique to modify a relational database based on a type of restructure
    Patent number: 6546395
    Abstract: A method, apparatus, and article of manufacture for improving multi-dimensional restructure performance by selecting a technique to modify a relational database based on a type of restructure. A command is executed in a computer to perform a database operation on a relational database stored on a data store connected to the computer. It is determined that a multi-dimensional database has been modified. Modifications to one or more original tables in a relational database corresponding to the multi-dimensional database are identified. A technique for modifying the relational database to correspond to the multidimensional database is selected based on the identified modifications.

  • Multi-dimensional restructure performance when adding or removing dimensions and dimensions members
    Patent number: 6542895
    Abstract: A method, apparatus, and article of manufacture for improving multi-dimensional restructure performance when adding or removing dimensions and dimension members. A command is executed in a computer to perform a database operation on a relational database stored on a data store connected to the computer. It is determined that a multi-dimensional database has been modified. Then, it is determined that the modified multi-dimensional database requires modifications to one or more original tables in a relational database corresponding to the multi-dimensional database. The modifications are incorporated into one or more new tables by copying data from the original tables into the new tables.
