Data types store information about specific sets of data, including ranges of values, the operations that can be performed on those values, and how the values are stored in memory. You can improve performance by using the appropriate data type for your data. For instance, avoid assigning a data type of CHAR to values that only contain numeric data. And whenever possible, choose efficient data types over the more expensive numeric and string types.
