Overview: Monet is an extensible (relational) database system. The authors implemented a set of GIS extension modules (Point, Box and Polygon) to demonstrate their approach and its applicability to GIS databases.

Features:

Decomposed Storage Model (DSM)

Line: 19 to 14

Shared-memory parallelism
- All processes share the same memory (or address) space

Concerns:

Main memory:
- Can even large raster databases fit into main memory as required by Monet?
- For example, the authors state that they "did not have sufficient disk space to generate all 130 rasters for the National benchmark" (Section 5)
What about raster data? Are there any modules for it?

Questions:

What's a database hot-set?
What are typical sizes for GIS dbs? Raster files? Vector files?

Features:

Decomposed Storage Model (DSM)
- Involves the decomposition of all relations into binary (association) tables, one for each attribute in the original relation
Main memory dbs
Algebra-extensible
Shared-memory parallelism
- All processes share the same memory (or address) space
