CONTENT AND OBJECTIVES:
    1. Concepts
      • Examine data modeling tools.
      • Demonstrate the use of a data modeling tool, such as ERWin, MS Visio, Rational or PowerDesigner.
      • Diagram a simple model.
    2. Data Entity Types
      • An integrated case study is used for exploring and analyzing data modeling.
      • Automobile rental system case study: Determine the data entity types; the initial documentation will be for logical design.
      • Utilizing the client-specific diagram tool, define the external and conceptual level of the database.
    3. Data Mapping Conventions
      • Become familiar with diagram notation and conventions.
      • Document the business strategies and clarifying diagrams from the Data Entity Types case study.
      • Use the conventions and diagramming techniques presented in lecture.
    4. Data Modeling
      • Create the data model, relationships, and entities to complete the case study.
      • Improve and refine the model to include the recursive relationships, strong and weak entity types, cardinality constraints, and appropriate comments.
      • Review each model for completeness, conformity to standards, optimal design, clarity, and consistent definitions.
    5. Design Aspects
      • Determine whether denormalization is needed and the level of denormalization which is required.
      • Calculate the physical cost to retrieve the data and empirically determine whether denormalization is required.
      • Review the data model to determine if the appropriate level of denormalization has been used and whether there is an alternative to denormalization for completing proper design.
    6. Data Attribute Types
      • Acquire facility in identifying keys, categorizing the key type, and determining alternative techniques.
      • Review the selection, type and size of the keys, and if required, perform a final normalization or denormalization.
      • Perform a review of physical design, including the level of the indexes, type of keys and how it affects the design.
