Abstract: A system for generating a relational database based on a fixed set of statement types. Each statement type defines a permitted relationship between a subject noun type, a verb, and an object noun type. The statement types are the basis for user defined statements. Each user-defined statement links a subject noun with an object noun by way of a verb. In addition, each statement may contain one or more prepositional phrases, consisting of a preposition type and an object of preposition noun. The preposition types and object of preposition noun types are defined by a fixed set of prepositional phrase types. The user defined statements represent the user's relational database, and form the basis for responding to various user queries. Statements are defined through a number of steps, during which the statement types are used to control the user's selections as to subject noun, verb, and object noun.
