DM-17 - Object-based spatial databases
- Discuss the merits of storing geometric data in the same location as attribute data
- Evaluate the advantages and disadvantages of the object-based data model compared to the layer-based vector data model (topological or spaghetti)
- Describe the architectures of various object-relational spatial data models, including spatial extensions of DBMS, proprietary object-based data models from GIS vendors, and open-source and standards-based efforts
- Differentiate between the topological vector data model and spaghetti object data with topological rulebases
- Write a script (in a GIS, database, or Web environment) to read and write data in an objectbased spatial database
- Transfer geospatial data from an XML schema to a database
- Discuss the degree to which various object-relational spatial data models approximate a true object-oriented paradigm, and whether they should
