Abstract
Techniques for simplifying the aggregation of data stored in a number of objects in a database system. A user-defined type and an object view are associated with a kind of data to be aggregated. The object view specifies the locations of the data in the objects and maps the data to be aggregated into the user-defined type. An application program interface includes a fetch interface that causes the database system to make a query over the object view associated with the kind of data and return the aggregated data in a set of objects of the user-defined type. The returned data is converted to XML and may be further transformed using XSL stylesheets. The application program interface further includes a filter interface that specifies a restriction for the query, a count interface that specifies the number of objects to be returned at once by the application program interface, a transform interface that specifies an XSL style sheet, and a transform parameter interface for providing parameters to the XSL style sheet. The techniques may be used to aggregate metadata for various classes of objects from a data dictionary in a database system. In this application, each class of object has a…
