Abstract
A system of the present invention includes a relational database management system (RDBMS), having an object-based, interactive visual-programming language providing programming by 'visual inheritance.' A user places screen objects (e.g., boxes, screen buttons, table objects, and the like) on an on-screen window or 'form,' visually attaches selected 'properties' and 'methods' to the screen objects, and then establishes an containership-based event model that dictates how and when these properties and methods will be invoked. An object inherits (derives) properties and methods from other (parent) objects via its visual containership. In this manner, the task of creating and maintaining application programs is greatly simplified.
