Abstract: The described arrangements and procedures provide a directory schema with object classes that have flexible attributes. This means that attributes can be extended independent of modifications to the directory schema. Specifically, an object instance of a content class described in the directory schema is instantiated. The content class includes a flexible attribute having a data type. A property is assigned to the attribute. The property is any combination of an operational and data providing property. The property is independent of the attribute's data type. Thus, without modifying the directory schema, multiple instances of the same object class can have attributes that provide completely different data types and completely different data operations.

Abstract: In a database management system (DBMS) (60) for a database application (10) including a database (12) having a table (14, 16, 18) and a unique key index (42) having indexes (44, 46, 48) therefor, the DBMS (60) includes a data manager (64), an index manager (66), a transaction manager (62), and a lock manager (68) which restricts access to the table by assigning locks to elements thereof. In order to avoid deadlock in the database application due to the pseudo-deleted entries, the lock categories include an X-lock and a Conditional S-lock, and have lock attributes including at least a Delete attribute for the X-lock. The Conditional S-lock is compatible (granted by the lock manager) with an X-lock whose Delete attribute is NOT SET, but is not compatible (granted) with an X-lock whose Delete attribute is SET. Each index entry includes a pseudo-delete flag which is SET by the index manager (66) to indicate deletion of the indexed row.

Abstract: A system and method to take data, which is in the form of an n-dimensional array of binary data where the binary data is comprised of bits that are identified by a bit position within the n-dimensional array, and create one file for each bit position of the binary data while maintaining the bit position identification and to store the bit with the corresponding bit position identification from the binary data within the created filed. Once this bit-sequential format of the data is achieved, the formatted data is structured into a tree format that is data-mining-ready. The formatted data is structured by dividing each of the files containing the binary data into quadrants according to the bit position identification and recording the count of 1-bits for each quadrant on a first level. Then, recursively dividing each of the quadrants into further quadrants and recording the count of 1-bits for each quadrant until all quadrants comprise a pure-1 quadrant or a pure-0 quadrant to form a basic tree structure.

Abstract: Business data (including transactional data) may be gathered, stored, sorted, and/or collated into financial service organization (FSO) reports used by various entities of a FSO. A processing relationship configuration program may be used to create a processing relationship structure between various entities of the FSO. Processing relationship structure information may be stored on a database of an FSO. Nodes may be created and uniquely defined to represent FSO physical entities and/or FSO functions. A nodes structure may correspond to the processing relationship structure within an FSO. In some embodiments, an FSO application program, such as a report program, may be generated based on a defined processing relationship structure. The report records may be arranged in a particular sequence by one or more of the break key fields. Changes to the processing relationship structure may be automatically reflected in the reports generated by the report program.

Abstract: A package management information recording section 131 creates a directory for each package for content distributed in package units, and creates a package management file indicating the relationship between a directory name and package identifier. A content file recording section 132 creates a content file group management file indicating the relationship between a content file name and a reference name when that content is linked from other content. A link resolution information recording section 133 creates a link resolution file indicating the correspondence between a reference name indicating content included in another package and the package identifier of the other package. A link resolution section 142 of a content playback apparatus 140 specifies a link destination content file using these items of file management information. By this means, a link between contents can be maintained even when distributed content is recorded with a name different from the original content file name.

Abstract: The present invention pertains to the field of computer software. More specifically, the present invention relates to populating, indexing, and searching a database of fine-grained web objects or object specifications. An embodiment of the invention is directed to a method of searching resources on the web. A query is received to search for information on the web and one or more web pages and one or more subsets of one or more web pages are accessed. The subsets have been extracted from one or more web pages prior to receiving the query. The subsets are extracted responsive to one or more views. The one or more views are defined independently of the search query. The views are content-sensitive filters that specify which subparts of a web page a user is interested in. Prior to receiving the search query, the subsets are stored in a database. Responsive to the search query, at least one or more of the extracted subsets of one or more web pages stored in the database is identified.

Abstract: A method and a system for downloading data from an auto-storage database are proposed, allowing a server to perform one-time data retrieval for transmitting data to terminal devices that request for data downloading. Upon receiving a connection request from a terminal device, the server stores an IP address of the terminal device into an IP address temporary storage area. Then, the server starts timing, and performs one-time data retrieval for retrieving data from a database if counted time reaches a preset time value pre-stored in the server. The retrieved data is transmitted by the server to the terminal device whose IP address is stored in the IP address temporary storage area, and then the terminal device requests for terminating the connection to the server for stopping data transmission. The foregoing method and system are advantageous of not to occupy too much network bandwidth even in operation of many terminal devices.

Abstract: A method for allowing faster data structure type checking. In one embodiment, successive type hierarchy references corresponding to a data object are cached within the data structure of the data object. The data structure may include a sub-root log to store successive supertypes (type hierarchy references) of the data structure type hierarchy. This allows for fast type checking as only the sub-root log need be accessed to determine class membership. In one embodiment, three fields are used to store the three successive references to a given type's supertype hierarchy. In an alternative embodiment, all references to a given type's supertype hierarchy may be stored in a type data structure. In another alternative embodiment, the number of type hierarchy references used may be dynamically determined at run time for a given application.

Abstract: The invention describes a method and apparatus for structuring, maintaining, and using families of data. According to the invention, given one or more sets of partitioning data, one may construct a set of families based on the values of fields and attributes of the records in a database system. The families are stored and managed in separate tables. The records in data tables are identified as belonging to one or more families. Furthermore, families may be represented in a hierarchical structure. Families may also inherit from each other based on a parent to child relationship also stored in the database. The invention provides means for fast and organized retrieval of sets data from a database. These and other features greatly facilitate automatic and consistent document generation.
