Matching data representations and categories
Choosing the proper data type for representing the data to be stored in a database is an important aspect of database development. This choice has ramifications for how the data can be used, how much space is required to store the data, and how resilient the database is to the introduction of erroneous data. This exercise will allow you to identify the best data category for different data values.
