摘要： An apparatus, system, and method are disclosed for supporting storage functions using an embedded database management system. The apparatus includes a disk controller configured to receive input/output (I/O) requests from a host, an embedded database management system module, and a conversion module configured to translate the input/output requests into database requests and communicate the database requests with the embedded database management system module. The system may include the apparatus, a network, and a plurality of storage devices coupled to the network and configured to store data. The method includes receiving input/output (I/O) requests from a host, translating the input/output requests into database requests, communicating the database requests with an embedded database management system module, and executing the database requests.

摘要： A client-server relational database system, wherein data from the client computer is encrypted by the client computer and hosted by the server computer, the encrypted data is operated upon by the server computer, using one or more operators selected from a group of operators comprising: (a) inequality logic operators, (b) aggregation operators, and (c) wildcard matching operators, to produce an intermediate results set, the intermediate results set is sent from the server computer to the client computer, and the intermediate results set is decrypted and filtered by the client computer to produce actual results. The group of operators is limited because the encrypted results set, when decrypted, includes inaccuracies therein. The client computer applies a set of correction procedures to the decrypted results set to remove the inaccuracies therein.

摘要： An apparatus, system, and method are disclosed for provisioning database resource within a grid database system. The apparatus comprises an analysis module and a provision module. The analysis module analyzes a data query stream from an application to a database instance and determines that the data query stream exhibits a predetermined performance attribute. The provision module provisions a database resource in response to a determination that the data query stream exhibits the predetermined performance attribute. The provisioned database resource may be a database instance, a database server, or a cache. The provisioning of the new database resource advantageously is substantially transparent to a client on the database system.

摘要： The present invention provides a computer-readable medium and system for selecting a set of n-grams for indexing string data in a DBMS system. Aspects of the invention include providing a set of candidate n-grams, each n-gram comprising a sequence of characters; identifying sample queries having character strings containing the candidate n-grams; and based on the set of candidate n-grams, the sample queries, database records, and an n-gram space constraint, automatically selecting, given the space constraint, a minimal set of an n-grams from the set of candidate n-grams that minimizes the number of false hits for the set of sample queries had the sample queries been executed against the database records.

摘要： Some aspects of the invention provide methods, systems, and computer program products for creating a static dictionary in which longer byte-strings are preferred. To that end, in accordance with aspects of the present invention, a new heuristic is defined to replace the aforementioned frequency count metric used to record the number of times a particular node in a data tree is visited. The new heuristic is based on counting the number of times an end-node of a particular byte-string is visited, while not incrementing a count for nodes storing characters in the middle of the byte-string as often as each time such nodes are visited. The result is an occurrence count metric that favours longer byte-strings, by being biased towards not incrementing the respective occurrence count values for nodes storing characters in the middle of a byte-string.

摘要： An in-place reorganization of a database achieves reasonably accurate results for users during high-throughput concurrent usage of the database. The reorganization's movement of records across a user transaction's position within a scan of the database is tracked. The behavior of the user transaction is corrected to account for the movement of the records.

摘要： Many web applications require access to a relational database. The requirements of such web applications are different from conventional applications that access a database. Web applications need to have selective recoverability and need to have support for different transaction structures, other than the flat transaction structure of conventional database applications, including nested and chained transactions. To achieve this, an interface between the application and database has the following functional features: 1) the interface to the database is connection oriented, i.e., the connection is retained across several invocations of the application; 2) the backend of the interface is long living, i.e., it exists across multiple invocations; 3) state information about a session in progress is maintained, and more specifically, it is distributed between the backend of the interface and the hidden fields of the HTML output document.

摘要： An apparatus comprises a hardware accelerator coupled to a memory. The hardware accelerator comprises one or more decompression units. The one or more decompression units are reconfigurable. The hardware accelerator may be a field-programmable gate array. The hardware accelerator may also comprise one or more reconfigurable scanner units. The one or more decompression units, in the aggregate, are operative to decompress one or more rows of a database at a bus speed of the coupling between the hardware accelerator and the memory. Two or more decompression units are operative to decompress two or more rows of a database in parallel. The apparatus allows for hardware accelerated row decompression.
