database management systems

DM-05 - Extensions of the relational model
  • Explain why early attempts to store geographic data in standard relational tables failed
  • Evaluate the adequacy of contemporary proprietary database schemes to manage geospatial data
  • Describe standards efforts relating to relational extensions, such as SQL:1999 and SQL-MM
  • Evaluate the degree to which an available object-relational database management system approximates a true object-oriented paradigm
  • Describe extensions of the relational model designed to represent geospatial and other semistructured data, such as stored procedures, Binary Large Objects (BLOBs), nested tables, abstract data types, and spatial data types
DM-04 - Object-oriented DBMS
  • Describe the basic elements of the object-oriented paradigm, such as inheritance, encapsulation, methods, and composition
  • Evaluate the degree to which the object-oriented paradigm does or does not approximate cognitive structures
  • Explain how the principle of inheritance can be implemented using an object-oriented programming approach
  • Defend or refute the notion that the Extensible Markup Language (XML) is a form of object-oriented database
  • Explain how the properties of object orientation allows for combining and generalizing objects
  • Evaluate the advantages and disadvantages of object-oriented databases compared to relational databases, focusing on representational power, data entry, storage efficiency, and query performance
  • Implement a GIS database design in an off-the-shelf, object-oriented database
  • Differentiate between object-oriented programming and object-oriented databases
DM-03 - Relational DBMS
  • Explain the advantage of the relational model over earlier database structures including spreadsheets
  • Define the basic terms used in relational database management systems (e.g., tuple, relation, foreign key, SQL, relational join)
  • Discuss the efficiency and costs of normalization
  • Describe the entity-relationship diagram approach to data modeling
  • Explain how entity-relationship diagrams are translated into relational tables
  • Create an SQL query that extracts data from related tables
  • Describe the problems associated with failure to follow the first and second normal forms (including data confusion, redundancy, and retrieval difficulties)
  • Demonstrate how search and relational join operations provide results for a typical GIS query and other simple operations using the relational DBMS within a GIS software application
