Abstract: An apparatus and method for generating and displaying a schema diagram of a database includes a schema diagrammer that automatically queries a database to determine its objects and relationships, and generates a graphical representation of the database in the form of a schema diagram that is displayed to the user. The schema diagrammer may optionally include a search filter to potentially constrain which objects and relationships in the database are included in a diagram data file, and a display filter to potentially constrain which objects and relationships stored in the diagram data file are displayed in the schema diagram.

Abstract: An automated name searching system incorporates an automatic name classifier and a multi-path architecture in which different algorithms are applied based on cultural identity of the query name. The name classifier operates with a preemptive list, analysis of morphological elements, length, and linguistic rules. A name regularizer produces a character based computational representation of the name. A pronunciation equivalent representation such as an IPA language representation, and language specific rules to generate name searching keys, are used in a first pass to eliminate database entries which are obviously not matches for the query name. The methods can also be implemented as a callable set of library routines including an intelligent preprocessor and a name evaluator that produces a score comparing a query name and database name, based on a variety of user-adjustable parameters. The user-controlled parameters permit tuning of the search methodologies for specific custom applications.

Abstract: The multidimensional database system automatically adds a new group in the existing layer information. Although the existing layer information does not have the corresponding layer structure information for the newly added group or members, the multidimensional database system has a flexible feature to generate the layer information for the newly added group to accommodate the addition in a logical manner.

Abstract: Disclosed is a system, method, and apparatus for calculating metrics by using hierarchical level metadata to describe the various structures within the database. The hierarchical level metadata permit calculation of complex metrics by an analytical server which would otherwise be difficult or impossible. As a result of the way that the analytical server calculates the metrics, slicing and drilling are supported. Additionally, dimension and fact level security are also supported.

Abstract: A load balancing mechanism maps a binary tree representation of a routing table into a set of fixed size memories. The mechanism efficiently utilizes the memory in the routing table without violating the tree precedence constraints and the memory access requirements of a pipelined system. The mechanism stores a subtree associated with a densely populated level of the binary tree in memory associated with lower levels.

Abstract: Instructions are generated to manipulate target objects and relationships in a relational database when a source object having a one-to-many relationship of privately owned type with the target objects is manipulated. To generate instructions, mapping meta-data is used which contains information as to how object classes of the object model map to tables in the database and how relationships map to foreign keys.

Abstract: 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.

Abstract: An analytical database system provides access to all of the data collected by an entity in interactive time. The analytical database system transforms relational database data. The relational database is denormalized and inverted such that the data fields of tables in the relational database are stored in separate files that contain a row number field and a single data field. At least one of the files, that contains repeating data values that are stored in successive rows, is compressed. The files include files with partition values and files with analytical data. Processing of the files is distributed by creating sub-rowsets of the files and by assigning the sub-rowsets to servers. The partial result sets are merged into a complete result set.

Abstract: A technique for manipulating objects at a computer is described. The technique includes receiving one or more requests to manipulate an object, wherein each request is received from a different thread. Each request to manipulate an object generates a copy of the object and a unique identifier for each copy of the object. A request to manipulate a copy of an object is distinguished from other requests to manipulate other copies of the object using the unique identifier. Additionally, a technique for accessing objects at a computer is described. The technique includes receiving a request from a client process for an object which is stored in an object server. A library server process is allocated to handle the object request. Transfer of the requested object is initiated. Thereafter, the library server process that was allocated to the object request is released.

Abstract: A database system that accommodates any type of phenomenon or thing, with a simple table structure and an extremely small-scale program. Category identification information of the content to be registered, item names that represent an attribute and/or a function included in the category, and attributes of data representing the substantial contents of these items (item data attributes) are registered in each data cell of a data property table (21) in units of rows, and category identification information, title names, and substantial contents associated with each item are registered in data cells of a main data table (22) in units of rows. The item names of the table (21) and the substantial contents of the table (22) correspond by means of cell numbers, and when a database management system (10) performs data input, storage, searching, and output, the various methods are generated with row-direction data of the table (21) as a message.

Abstract: In a computer system including a database system wherein queries to the database system can be specified by selecting a first object and a second object, with a query result being based on a relationship between the first object's metadata and the second object's metadata, relationships are generated by automatically populating a relationship matrix having undefined relation cells therein from pre-defined relationships represented by defined relation cells in the relationship matrix and transitively completing a local set of relationships defined in the relationship matrix.

Abstract: To identify and describe one or more topics in one or more documents in a document set, a term set process creates a basic term set from the document set where the term set comprises one or more basic terms of one or more words in the document. A document vector process then creates a document vector for each document. The document vector has a document vector direction representing what the document is about. A topic vector process then creates one or more topic vectors from the document vectors. Each topic vector has a topic vector direction representing a topic in the document set. A topic term set process creates a topic term set for each topic vector that comprises one or more of the basic terms describing the topic represented by the topic vector. Each of the basic terms in the topic term set associated with the relevancy of the basic term. A topic-document relevance process creates a topic-document relevance for each topic vector and each document vector.
