An improved command handler (and database system utilizing the improved command handler) interfaces to a datastore storing item data for a plurality of items and bi-directional modifier data, corresponding to a relation between at least one first item and at least one second item, that represents first text characterizing semantics of a relationship of the at least one first item to the at least one second item, and represents second text characterizing semantics of a relationship of the at least one second item to the at least one first item. The command handler operates, in response to receiving a first-type query command that specifies at least one given item, to access the datastore to identify i) at least one related item that is related to the given item, and identify ii) either the first text or the second text characterizing semantics of the relation between the given item and the at least one related item. The command hander returns i) data corresponding to the at least one related item; and ii) data corresponding to the identified first text and or second text characterizing semantics of the relation between the given item and the at least one related item. Preferably, the data returned in response to the first-type query command identifies the at least one related item. and identifies the first text or second text characterizing semantics of the relation between the given item and the at least one related item. In addition, the command handler preferably supports additional commands that retrieve from the datastore information related to specified objects, object types, and relations.The command handler (and database system) of the present invention may be used in a wide assortment of software applications, including enterprise applications (such as e-business applications, supply chain management applications, customer relationship management applications, decision support applications), the file system in operating systems, web browsers, e-mail applications and personal information management applications. Importantly, the command handler (and database system) provides an efficient mechanism to query the organization of the data elements (and the relationships therebetween) stored and accessed in such software applications, in a manner that efficient and readily adaptable to client-server database systems or other distributed database systems.

A system for capturing, analyzing, storing and reporting system-users' usage of multiple internet and/or intranet web servers. At each web server in the system, the actions by the system-user create a server log that is processed by the system on a continuous basis. The processing at the server may include, by way of illustration, filtering the logs of about 75 percent of the data and decrypting a system-user's cookie. On a periodic basis, one or more collection servers in the system copy the processed log files from each web server on the system, zip the files, and transfer the files to an analysis server. After the collection is complete, an analysis server processes the data and stores it in a relational database that supports various user specified daily, monthly and quarterly reports of the usage data.

A method (and corresponding database system) for displaying in a view window information characterizing semantics of relations between objects. For each given relation between at least one subject object and at least one direct object, bi-directional modifier data is stored that represents first text characterizing semantics of a relationship of the at least one first object to the at least one second object, and represents second text characterizing semantics of a relationship of the at least one second object to the at least one first object. In response to predetermined user input associated with an object node displayed in the view window, a set of relations whose at least one subject object or at least one direct object is associated with the object node is identified. For at least one relation in the set of relations, the view window is updated to include a second node comprising a graphical representation of: the first text of the given relation in the event that the given object is a subject object in the given relation, or the second text of the given relation in the event that the given object is a direct object in the given relation. The second node may be a relation node associated with a given relation, or a mixed node associated with a relation-type pair. In response to predetermined input with a second node, the second node may be expanded to identify and display one or more object nodes (identifying direct object(s) of relations derived from expansion of a subject object associated therewith or identifying subject object(s) of relations derived from expansion of a direct object associated therewith). Preferably, this expansion routine is recursive in nature.The method (and database system) of the present invention may be used in a wide assortment of software applications, including enterprise applications (such as e-business applications, supply chain management applications, customer relationship management applications, decision support applications), the file system in operating systems, web browsers, e-mail applications and personal information management applications. Importantly, the method (and database system) provides an easy, user friendly and efficient mechanism to define, view and query the organization of the data elements (and the relationships therebetween) stored and accessed in such software applications, in a manner that conveys the real-world meaning of such relationships.

Techniques and systems for indexing and retrieving data and documents stored in a record-based database management system (RDBMS) utilize a search engine interface. Search-engine indices are created from tables in the RDBMS and data from the tables is used to create “documents” for each record. Queries that require data from multiple tables may be parsed into a primary query and a set of one or more secondary queries. Join mappings and documents are created for the necessary tables. Documents matching the query string are retrieved using the search-engine indices and join mappings.
