Abstract: A data model representing a multi-model database of a product system includes a multi-model repository that holds said multi-model database's artifacts under version control. The multi-model repository holds a plurality of constituent models, wherein each model represents a discrete aspect of the system, a model registry containing a list of the constituent models in the multi-model database, a set of input attributes and a set of output attributes corresponding to each of the models, a set of interfaces representing a tuple corresponding to each of the models, a set of attribute constraints associated with the input and output attributes; and a set of notifications associated with each of the models for informing the models of defined events.

Abstract: A computer implemented application development (authoring) system permits objects (such as VBX custom controls) to be graphically inserted into the program under development by dragging and dropping associated icons into one of four views. The properties associated with the object may then be assigned settings. Development of a complete application is accomplished by visually arranging, ordering, and interconnecting the objects without the necessity of writing any code. The four views of Output, Map, Multitrack, and Workform may be synchronized so that changes made to the program in one view are simultaneously reflected in all other views. The system generates as output a script listing the objects and their properties which is then executed by a separate run time program. The system permits use of objects written to a standard specification and the addition at any time of additional objects written to that.

Abstract: A computer database system for multi-model integration includes remote client-side components and a multi-model database having a plurality of artifacts that define the multi-model database and a multi-model repository that holds the artifacts under version control. The remore client-side components include a multi-model manager, one or more connectors, execution automation engine, a sandbox, and a version control system client.

Abstract: A computer system for scheduling events between end users of the system. Each end user is granted a unique password protected personal calendar. This calendar is generated from information stored in a database at a central server, and delivered to each end user as standard HTML sent through the Internet. This custom personal calendar is then viewed by the end user in a standard Web Browser. This obviates the need for special software programs to be purchased by end users, and also allows end users of any CPU type to read their calendars. When an end user uses the system to send an Invitation or Announcement to others on the system, the sending end user has the option of sending Email in addition to posting that information in the calendars' of others. When an end user sends an Invitation or Announcement to a person who is not an Appointnet user, then the Appointnet system automatically creates a unique calendar for the recipient, and sends and Email to that person.
