The Problem
“closed” applications proprietary data exchange formats obscure data semantics no reuse due to poor documentation
heterogeneous isolated tools
tool 2
tool 3
tool 1

Advantages from CORBA/OODBMS integration
Independence from concrete platform, programming environment and concrete database system makes the data accessible for arbitrary remote applications manage complex object relations in understandable manner
Applications can manipulate with persistent objects directly in the database reduces network traffic of data keeps clients thin makes data concurrently available improves data consistency

Advantages of Integration
Improves consistency of 3D Models
Allows working on parts of large 3D models
Extends the set of usable geo-scientific tools
Provides openness and reusability of the data and methods
