摘要:
A method of transforming queries based upon an entity/relationship schema into multi-dimensional expression queries is provided. The method comprises matching an object referenced in an entity/relationship schema based report specification to a corresponding object in the entity/relationship schema, the corresponding object adorned with associated multidimensional metadata; adding the associated multi-dimensional metadata to the object referenced in the entity/relationship schema based report specification; translating the entity/relationship schema based report specification into a multi-dimensional expression query; and retrieving directly all data required to populate a report output of the entity/relationship schema report specification.
摘要:
A system for transforming queries based upon entity/relationship schema into multi-dimensional expression queries is provided. The system comprises a binding module for matching an object reference in a report specification to a corresponding entity/relationship schema object and adding associated multi-dimensional metadata information from the entity/relationship schema to a corresponding report specification object, and a query translation module for translating the report specification into a single multi-dimensional query.
摘要:
A multidimensional query results processing system for translating output of an execution of a multidimensional query into a data result set that reflects the semantics of an entity/relationship schema report specification is provided. The system comprises a result set description generation module for producing a result set description that reflects the semantics of the report specification, a tabular row generation module for converting the results of the single multi-dimensional query into a collection of rows of data, a tabular summary level calculation module for calculating a summarization level of a row a data, a tabular header row generation module for producing a header row to include in the row of data, and a cross-tabulated result generation module for converting the results of the single multi-dimensional query into a result set that matches the semantics of the report specification.

摘要:
A mechanism for summary filter transformation is provided. The mechanism comprises a summary filter analysis module for analyzing a multidimensional query that is not supported by a target database system, and a summary filter transformation module for transforming the multidimensional query into a semantically equivalent query that is supported by the target database system.
