The technology incorporated into business flow Comprised of two systems – one to handle the spatial elements, another to manage attribute data.
TOPICS COVERED: (in pointers)
- Most hybrid systems use a proprietary data model.
- Separate storage systems complicate database maintenance, increase disk access and network traffic
- Requires diligence, attention to detail and special applications to maintain feature-attribute linking.
- What happens when a user splits a line segment?
- Where does the original attribute records go?
- How do you maintain a historical record of line splitting?
- How are other GIS layers affected by splitting a pipe?
- Example of a Hybrid Model? (ARC/INFO, ESRI ShapeFile)
