    摘要: 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.

    摘要: A method, apparatus, and article of manufacture for DDL Extension layer that provides extended data definition language (DDL) capabilities for relational databases with multi-connections. 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. The command is received from one of a plurality of applications. One or more compensating operations are logged for the command, wherein each compensating operation corresponds to an action to be performed for a rollback or a commit operation. An identifier is associated with the compensating operations, wherein the identifier identifies a unit of work from which the command was received.

Selection of a subset of a cube model metadata object that is generated from a facts metadata object and one or more dimension metadata objects is received. The facts metadata object references one or more measure metadata objects. A statement is generated for retrieving multidimensional information using metadata in the cube model metadata object and the measure metadata objects, wherein each of the measure metadata objects specifies one or more aggregations.

    摘要: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A relational database has a fact table and at least one related dimension table. A dimension identifier is received that identifies a data block in a multi-dimensional database. The dimension identifier comprises one or more multi-dimensional member identifiers. Rows are accessed from the fact table through the related dimension tables using the received dimension identifier. Then, the accessed rows are formatted as a data block for the multi-dimensional database.

    摘要: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A multi-dimensional database is defined having a set of multi-dimensional data blocks and a set of identifiers comprising selected dimensions of multi-dimensional data for identifying particular ones of the multi-dimensional data blocks. The set of identifiers provides an ordering of the multi-dimensional data blocks using multi-dimensional member identifiers and holds usage information and age information about the multi-dimensional data blocks. The data in the set of multi-dimensional data blocks is stored in a relational database that represents the multi-dimensional database. Then, a set of rows representing a multi-dimensional data block is accessed from the relational database.CROSS-REFERENCE TO RELATED APPLICATIONS

    摘要: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A multi-dimensional database is represented as a relational schema in the relational database. The multi-dimensional database has one or more dimensions having one or more members. Each value in the multi-dimensional database is identified by the intersection of one member from each dimension. The relational schema includes a fact table and related dimension tables. The fact table has a dimension column for all but one of the dimensions of the multi-dimensional database and a value column for each member of the remaining dimension. The fact table has at least one row that contains the values corresponding to the intersection of the members identified by the dimension columns and the members associated with the value columns. Each dimension table has a row for each member of a dimension. At least one dimension table has one or more attribute columns for holding attribute values for members defined by the dimension table.
