Methods and apparatus for generating a report from hierarchically formatted data are disclosed. First, a data source including one or more files having a hierarchical file format is identified, where each of the files includes one or more data elements. A relational database model is obtained, where the relational database model includes one or more virtual tables, each of the virtual tables including one or more virtual columns. The relational database model is then mapped to the hierarchical file format. A query may be obtained using the virtual relational database. Data is then obtained from the virtual relational database corresponding to the query, thereby enabling a report including the data to be generated.

Object persistence is facilitated by introducing persistent agents to act as bridges between the programming model and the database model. Persistent agents are instantiated on a per-class basis and are responsible for mapping their class to a suitable database related. Methods are defined for the persistent agent to specify database-specific properties and optimization hints.

A method and system for providing an open database model that allows the combining of spatial and Attribute data in a single relational database. The integration of spatial and Attribute data allows the data to be accessed by either standard structured query language (SQL) or a GIS viewing application. The invention provides: enhanced performance by avoiding proliferation of segmentation; open dynamic segmentation; integrated temporal data; and automated database maintenance. Permanent anchor sections are provided to define spatial references. The data model allows for intersections in the interior of a link (anchor section), resulting in a more stable form of a link, or anchor section. The use of anchor sections simplifies maintenance of data associated with the anchor sections and facilitates the use of anchor sections in a distributed environment. Database views display data in a simple, tabular format. Access to a continuous archive of historical data is supported.

A distributed speech recognition system and method thereof in accordance with the present invention enables a word and a natural language to be recognized using detection of a pause period in a speech period in an inputted speech signal, and various groups of recognition vocabulary (for example, a home speech recognition vocabulary, a telematics vocabulary for a vehicle, a vocabulary for call center, and so forth) to be processed in the same speech recognition system by determining the recognition vocabulary required by a corresponding terminal using an identifier of the terminal since various terminals require various speech recognition targets. In addition, various types of channel distortion occurring due to the type of terminal and the recognition environment are minimized by adapting them to a speech database model using a channel estimation method so that the speech recognition performance is enhanced.

The invention discloses a cluster database system. The cluster database system comprises a query analyzer and a plurality of database nodes. The query analyzer is used for analyzing a received query request, resolving the received query request into a query task stream and generating an execution rule; and meanwhile, the query analyzer is used for distributing one or more than one query task in the query task stream for corresponding database nodes according to the execution rule. The database nodes are used for executing corresponding query tasks together with other relevant database nodes according to the execution rule after the distributed query tasks are received; and besides, the database nodes are used for combining query data obtained through execution of a certain task and query data obtained through execution of the same query task by the other relevant database nodes so as to obtain query result data, and the data is the final query result data corresponding to the query request or the data is used as input data for the next query task and therefore the plurality of database nodes can carry out the query task stream according to the execution rule to obtain the final query result data conveniently.
