  • Publication number: 20050015468
    Abstract: This invention proposes a system which supports controlled recursive propagation of points of presence on connected networks, where the network is the internet, and the points of presence are functional or informational banners hosted by websites and displayable on HTML, javascript and/or java enabled browsers. In addition the points of presence support informational of functional communication between a plurality of designated origin servers and the points of presence. This allows data on the use, location, and other characteristics of the interaction between the user and the points of presence to be captured, transmitted, aggregated, stored, and/or manipulated as necessary. The said communication also allows the implementation of access permissions, registrations, or other forms of control. Similar data and communication is supported for the websites hosting the points of presence.

  • Patent number: 5809296
    Abstract: A reverse engineering technology is capable of automatically reversing from a physical data model comprising a relational or 4GL data model of an existing application database into a logical data model comprising classes and an entity-relationship (E-R) model of each class, the classes representing the different types of high-level objects that make up the application. This logical data model allows users to have a much clearer understanding of their application database thereby increasing their productivity and ease of maintenance of their existing applications. This is made possible by the method and structure of this invention first capturing the application semantics from the physical data model to provide a set of derived semantics. The derived semantics are then used to identify classes and derive the class definitions which are then used to derive the E-R model of each class.

  • Patent number: 5749079
    Abstract: An end user query technology is taught which is capable of automatically understanding the database model and guiding the user to scout for the desired information, thereby increasing productivity and ease of information access. The user is freed from the need to understanding the database model, with the end user query facility of this invention quickly guiding the user to acquire the information. This is made possible by the end user query facility of this invention first recapturing the application semantics from the existing database model to provide a set of derived semantics. The derived semantics are then used by the end user query facility to intelligently guide the user to scout for the desired information in the database. In addition, the derived semantics can be easily updated by the end user query facility when the database model is changed.
