Abstract
Improved database structure is described in which the fields of each database record are divided into two classes, navigational and informational data. The data in the navigational fields is stored in a topological map which may be viewed as a tree structure or the merger of two or more such tree structures. The informational data is preferably stored in a conventional relational database. Each leaf node in the topological map specifies a unique record in the relational database.
