What will be an ideal response?
Choosing the appropriate data type for each field in a table is essential for two reasons. First, it helps store the correct data in the correct format while using the least amount of space. Second, it eases data entry and interactivity with data because choosing certain data types results in user-friendly interactive features, such as drop-down menus, check boxes, and hyperlinks. Choosing the appropriate data type also lets you correctly manipulate the data.
