Techniques for modifying a query based on a data index of nodes in a data set are disclosed. A system modifies queries based on query terms associated with indexed data. The system modifies queries to include query terms based on indexed data or to obtain values for query terms that are not associated with indexed node properties. The system adds query terms, that reference indexed data, to a query in response to determining that none of a query's terms reference indexed data. The system derives values for query terms that are not associated with indexed node properties using a logical or mathematical formula. The system traverses parent nodes of a child node to identify values for query terms that are not associated with the child node in a data index, but are inherited from a parent node.

Index-based modification of a query

A database manager is disclosed that retrieves database records having binary encoded data from a database and instantiating objects in an in-memory database. Binary encoding compresses data, allowing many subrecords to be stored a single blob field of a database record. Retrieving chunks from storage reduces transfer time by reducing the size of data and the number of operations needed to retrieve all the subrecords. The database manager receives database access requests from a database application. Changes made to the database objects and committed by the application are written back to the persistent database as versioned delta records. In a subsequent session, loading the database from storage includes first loading the most recent snapshot record, then applying changes to the data stored in delta records. The changes stored in the delta records are applied to the data in the snapshot record in the order in which they were made.

Storing and versioning hierarchical data in a binary format

Embodiments of the present invention provide systems and methods of managing hierarchical reference data. According to one embodiment of the present invention, a hierarchical data management program can maintain a master set of reference data corresponding to the reference data being managed. From the master set of reference data, the hierarchy management program can instantiate centralized hierarchies, validate changes to the centralized hierarchies and enforce business rules with respect to the centralized hierarchies. The hierarchy management program can publish the centralized hierarchies to subscribing systems for use by the subscribing systems in managing data of interest.

Hierarchical reference data management system and method

A loudspeaker apparatus utilizing a ribbon diaphragm which is capable of transforming an electrical signal into an audio acoustical signal. The diaphragm includes a first side and a second opposite side. First and second magnets are also employed in the present invention and are mounted to the edges of the diaphragm such that the diaphragm lies in the magnetic field generated by the pair of magnets. A first plurality of spaced magnetic plates are stacked and extend continuously from the first magnet to the second magnet at the first side of the diaphragm. The first plurality of plates form a throat-shaped cavity of a predetermined size. A second plurality of spaced magnetic focusing plates are stacked on the second side of the diaphragm in the same manner. A plurality of sound damping shims are interposed each of the first plurality of magnetic focusing plates on the sides of the throat-shaped cavity. An acoustic coupler or horn may be easily attached to the throat-shaped cavity to enhance the lower acoustical response range.
