e r modeling

Now that you have defined your E-R model and project description in the project you started and worked on inWeeks 1 and 2, start converting your logical E-R model to a physical model.

In this week, complete the following tasks:

  • In a Microsoft Excel spreadsheet, define columns with the following headings:
    • Primary Key
    • Name of Column
    • Null (NorY)
    • Datatype
    • Description
    • Foreign Key
    • Foreign Key Table
  • Each row will contain your rows for this table.
  • Fill out the columns row-wise.
  • Using Microsoft Visio or Microsoft Paint, create an E-R model of the six tables from your spreadsheet for developing the business requirements and constraints that will maintain the business logic for your database.
    • The E-R model should be readable and should map to the spreadsheet and the project description.
    • It should have all the cardinality and optionality defined.
