Systems and methods for providing notifications of changes made in a database table to a remote application is presented. The system and methods manage change notification of a table in a database by notifying an application registered to receive notifications of changes made to a database table. A database manager executing on a device may receive a request to register an application to be notified when a first table of a plurality of tables in a database is changed. The database manager may establish a notification table comprising fields of the first table and one or more additional fields for managing notification. The database manager may establish a trigger on the first table to invoke a trigger procedure to copy a changed row of the first table to the notification table. The database manager may create a rule for the notification table to notify registered applications when a new row is inserted into the notification table.

A system for localizing an EPG program schedule, including an EPG service provider station including a database of channels and corresponding EPG program schedule information, a database manager identifying a plurality of channel line-ups potentially receivable at a viewing location, a transmitter, and a receiver, a multimedia viewer situated at the viewing location including an automatic channel line-up identifier identifying a first line-up of television channels receivable at the viewing location, a channel line-up processor at the viewing location calculating a channel line-up from among the plurality of channel line-ups that substantially matches the first line-up, a receiver receiving from the EPG service provider station the plurality of channel line-ups, and a transmitter transmitting to the EPG service provider station the identifier of the channel line-up calculated by the channel line-up processor, and a network connection linking the multimedia viewer to the EPG service provider, wherein the EPG service provider station transmitter transmits to the multimedia viewer the plurality of channel line-ups and also transmits to the multimedia viewer EPG program schedule information localized to the viewing location and based on the identifier of the channel line-up calculated by the channel line-up processor, and wherein the EPG service provider station receiver receives from the multimedia viewer the identifier of the calculated channel line-up, and wherein the multimedia viewer receiver also receives from the EPG service provider station the EPG program schedule information.

A system and method for trans-factor ranking of search results. Any number of attributes of items in a database being searched may be synthesized into a uniquely suitable ordering that brings relevant and authoritative results to the top of the list whenever such results exist in the database. The manner in which the attributes are used to create this ordering may be varied by users to tailor the ranking to their needs, and by database providers to take advantage of unique database contents. Attributes that are not in the database may be created dynamically and used to synthesize the order, based on the intersection between attributes that do exist in the database and attributes that are associated with the user or database manager. Attenuation and amplification factors are applied to attributes to control rankings. A multi-ranking interleaver determines a final ordering when more than one ranking strategy is used.
