摘要： A database management system that has bitmap values in which set bits in a representation of a bitstring specify a set of objects whose definitions are built into the database management system. The database management system further includes user-accessible operations on the bitmap values. The bitmap values are represented by means of a mapping specifier that specifies a range of the set of objects and a representation of a string of bits that has been mapped onto the set of object specified by the range specifier. The representation of the string of bits may be compressed. Bitmap operations on the values may alter the range specifier, the size of the string of bits, or individual bits in the string of bits. The objects represented by the bitmap values may be objects in the database management system or objects external thereto. An example of bitmap values of the first kind are bitmap values representing sets of rowids. rowid bitmap values may be used to make a user-defined index of attribute values for any set of objects contained in fields in the database management system. An example of bitmap values of the second kind are bitmap values representing sets of electronic product codes. ePC bitmap values may be used in any application where a compact representation of a set of ePC codes is desired.

摘要： A domain index for a partitioned database can be created using a user-defined indexing scheme. Partition maintenance operations performed on the partitioned database objects cause corresponding partition maintenance operations to be performed on the domain indexes. The user-supplied partitioning code is partition operation-unaware.

摘要： Domain indexes (indexes created and maintained by user-defined indexing schemes) are managed on partitioned database objects that store data using a system-managed approach. Partition maintenance operations performed on the partitioned database objects cause corresponding partition maintenance operations to be performed on the domain indexes. Partition maintenance operations are performed on both the database objects and the indexes by a system-supplied partition manager. Changes in the partition maintenance operations or partitioning methods supplied by the database management system do not affect user-supplied code which is provided by the user-defined indexing scheme. User-supplied code is therefore partition operation-unaware.

摘要： A method, system, and computer program product for normalized ranking of semantic query search results. The method commences by forming a SPARQL query, the SPARQL query specifying a collection of named RDF graphs, then executing the SPARQL query to retrieve matched documents selected from the collection of named RDF graphs. Having retrieved the matches, the method calculates an absolute normalized score for the matched document. The calculation of an absolute normalized score for a second matched document allows for relevance ranking. To enhance the relationship of the computer-calculated score to the relevance (and not solely to occurrence counts) embodiments consider the number of distinct variables selected in the SPARQL query, and also consider the total number of bindings to the aforementioned variables. For comparing from among possibly different sized documents, a further normalization component is implemented by considering the total number of triples found in the document's underlying subgraph.

摘要： The method for processing data in a relational database wherein ontology data that specifies terms and relationships between pairs of said terms expressed in an OWL document is stored in the database, database queries that include a semantic matching operator are formed which identify the ontology data and further specify a stated relationship between two input terms, and the query is executed to invoke the semantic matching operator to determine if the two input terms are related by the stated relationship by consulting said ontology data.

摘要： Systems, methodologies, media, and other embodiments associated with supporting queries with soft time constraints are described. One exemplary system embodiment includes logic for accepting a query having a soft time constraint. The example system may also include logic for rewriting the query having the soft time constraint into a query having a row limitation or a sample percentage limitation. In one example, the row limitation or sample percentage limitation are computed by repetitively comparing an estimated query execution time to the soft time constraint.
