Abstract: A relational database residing on a second computer, and is accessed by a user interface via a global information network such as the Internet. The relational database is accessed through four intermediate processing layers: an interaction layer, an application layer, a business object layer, and an information model layer, each located on a second computer, with the information model layer logically adjacent to the database, and the interaction layer logically adjacent to the user interface operating on the browser. The information model layer maintains a first relational tree of the information in the relational database. This relational tree appears as a plurality of entities in a mark up language (such as XML) to the business object layer and the information in the relational database is accessible via the relational tree.
