The system presented in this paper has several major advantages over the ArcGIS approach: it can be extended with new topology rules, it has a much wider set of rules, and it can mix feature attributes with topology rules as filters. In addition, the topology rule system can work with ...
The attributes and structure of the data type might be stored in a special table; the handling of this table, and the special operations for the data type might be built into the application itself. Isochronous data such as video clips might be stored on a file server and the file names ...

In object-oriented databases, the data containers are typically referred to as object classes, the records are referred to as objects, and the fields are referred to as attributes. Other database architectures may use other terminology. Systems that implement the present invention are not limited ...
