Data Requirements

Having identified the business requirements, it is necessary to examine them and determine the data needed to meet the requirements.

Analyze the form carefully to make a list of all the data needed to create the form. Do not be concerned about defining the data as a grouping of data (entity/file) or a property of the group (attribute/field). Some examples are shown here:

• Jockey
• Horse name
• Horse code
• Entry number
• Finishing position
• Race name
• Race distance
• Courses
• Course name
• Race time
• Going conditions
• Prize money
• Race date
• Dam (Horse’s mother)
• Sire (Horse’s father)
• Horse’s date of birth

Having specified the requirements of this application, you can now begin to build the CA 2E data model. This data model will serve as the foundation for the application design in CA 2E. The data modeling process is illustrated in the Data Modeling chapter.
