User Interface Apparatus and Methods

Abstract

In one aspect, the invention provides a digital data processing system for information storage and retrieval that includes a first digital data processor (e.g., personal computer, workstation, server, mainframe, etc.) coupled to a second digital data processor and a data store (e.g., a RDF data store, relational database, etc.). The first digital data processor creates, reads, updates and/or deletes data from the data store (i.e., “CRUD” operations) based on a model generated by the first digital data processor. The model comprises an ontology and a set of constraints that are applied to data characterized by the ontology.

1 . A digital data processing system, comprising:
 A. a first digital data processor coupled to (i) a second digital data processor and (ii) a data store,   B. a model comprising an ontology and a set of constraints,   C. the first digital data processor any of creating, reading, updating and deleting data from the data store based on code generated from the model by said first digital data processor.
