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
