A hardware accelerator for managing a computer database. The accelerator includes a key memory for storing a map of record key values to record address values, a search processor for searching the key memory for a given key value and providing the associated record address value to the central processor, and a bus interface for interfacing the search processor and the key memory to the central processor. Database management software executing on the central processor requests a mapping from key ...

While scalability in database processing may be achieved gradually and at low cost, to achieve high scalability of several thousand times. This database accelerator holds on an accelerator system copies of location tables, which correspond to primary-key indices, and alternate-key location tables, which correspond to alternate-key indices, for a primary system that performs data updates. When a location table or alternate-key location table on the primary system is modified, updates are synchron...

A method and system for bundling objects containing related data. Objects that are related to each other are bundled together to avoid synchronization problems. The bundling process is performed in parallel, as are operations, such as calculations, performed on the objects.

The system relates to a structure for the storage of data-information within a data-base, which information is structured into a hierarchy of nodes and which hierarchy consists in a tree-structure. This tree-structure has a root-node (1), possibly one or several intermediate nodes (2, 3) and one or more leaf-nodes (4), wherein the root-node (1) comprises one or more root-elements (1E), wherein respective intermediate nodes (2, 3) include one or more intermediate elements (2E1, 2E2, 2E3, . . . ),...

A database access method includes receiving a data request at a switcher system from another computer, selecting a connection to a database system from among a collection of connections, and communicating with the database system across the selected connection to fulfill the data request. A computer program residing on a computer readable medium includes instructions for causing a computer to receive a data request from another computer, select a connection to a database system from among a numb...

A data processing system including a processor device associated with memory device. The processor is capable of running user application programs to communicate with a database management system that includes database file management system, for accessing data records stored in the memory. The database file management system includes: a probabilistic access indexing file (PAIF) having a plurality of nodes and links. The leave nodes of the PAIF are associated with data records accessible to the ...

A database synchronizer facilitates computing systems which have client-side and server-side applications that share data in similar database structures, but which do not maintain a continuous connection to a single shared data source. In general, a database synchronizer is used to share data among many nodes on the computing system. The database synchronizer is used to synchronize the data in a central database for a particular client with the data on that client's intermittently-connected comp...

Information in a database is accessed with a computer system by transforming a file system request from an application into a database query and retrieving information corresponding to the database query from the database. The retrieved information is made available to the application as a file system object, for example, as a directory, a file, a link or a collection thereof.

System and method for processing information from a paper map source to produce an accurate high resolution digitized map database in matrix format having separate files for each selected feature. The system and method scans the input paper map source and processes the scanned data into a digitized map database in matrix format with distinct and selectable features as are represented on the input map. Selected features include vegetation, hydrography, lines of communication, miscellaneous featur...
