Database query handler supporting querying of textual annotations of relations between data objects

An improved command handler (and database system utilizing the improved command handler) interfaces to a datastore storing item data for a plurality of items and bi-directional modifier data, corresponding to a relation between at least one first item and at least one second item, that represents first text characterizing semantics of a relationship of the at least one first item to the at least one second item, and represents second text characterizing semantics of a relationship of the at least one second item to the at least one first item. The command handler operates, in response to receiving a first-type query command that specifies at least one given item, to access the datastore to identify i) at least one related item that is related to the given item, and identify ii) either the first text or the second text characterizing semantics of the relation between the given item and the at least one related item. The command hander returns i) data corresponding to the at least one related item; and ii) data corresponding to the identified first text and or second text characterizing semantics of the relation between the given item and the at least one related item. Preferably, the data returned in response to the first-type query command identifies the at least one related item. and identifies the first text or second text characterizing semantics of the relation between the given item and the at least one related item. In addition, the command handler preferably supports additional commands that retrieve from the datastore information related to specified objects, object types, and relations.The command handler (and database system) of the present invention may be used in a wide assortment of software applications, including enterprise applications (such as e-business applications, supply chain management applications, customer relationship management applications, decision support applications), the file system in operating systems, web browsers, e-mail applications and personal information management applications. Importantly, the command handler (and database system) provides an efficient mechanism to query the organization of the data elements (and the relationships therebetween) stored and accessed in such software applications, in a manner that efficient and readily adaptable to client-server database systems or other distributed database systems.

Plate number, body color and mark identification-based equipment and plate number, body color and mark identification-based method for identifying fake plate vehicles

The invention discloses a plate number, body color and mark identification-based equipment and a plate number, body color and mark identification-based method for identifying fake plate vehicles. The equipment comprises a video detector, a plate number positioner, a plate number identifier, a body color identifier, a mark positioner, a mark identifier, a database query and alarm device and the like. According to the characteristic that the local edge information of the plate number image is rich, the equipment can accurately position a plate number in a captured image, extract a body region and a rough mark position by using the position of the plate number, and accurately extract a body color and a mark according to the extracted rough position; and then the equipment identifies the characters of the plate number, the body color and the mark, compares the results of the three identifications with data stored in a database to determine if a vehicle is a fake plate vehicle, and gives an automatic alarm for law enforcement officials to stop the vehicle for further check if the vehicle is a fake plate vehicle. The equipment is good in structure, simple in operation, high in judgment accuracy and few in manually set parameters. The equipment can also be used for catching escaped defaulting vehicles, stolen vehicles and peccancy vehicles and the like.

Computer apparatus and method for caching results of a database query

A query processor caches data retrieved from executing prepared statements, and uses the cached data for subsequent accesses to the data, if certain conditions for using the cached data are met. The preferred embodiments also include a data staleness handler that takes care of issues that arise from data that may have changed in the database but is not reflected in the cache. One way to handle data staleness in the cache is to specifically enable or disable caching in a query. If caching is disabled, the query processor will access the data in the database. Another way to handle data staleness in the cache is to provide a timer that causes the cache to be invalidated when the timer times out. Yet another way to handle data staleness in the cache is to provide specified conditions that must be met for caching to occur, such as time or date limitations. Still another way to handle data staleness in the cache is to provide an update trigger for the data in the database that corresponds to the cached data. When the data in the database is updated, the update trigger fires, causing the cache to be invalidated. Note that invalidating the cache could also be followed by automatically updating the cache. By caching the results of processing a prepared statement, other queries that use the same prepared statement may be able to access data in the cache instead of going to the database.
