What is data type in database?

A database data type refers to the format of data storage that can hold a distinct type or range of values. When computer programs store data in variables, each variable must be designated a distinct data type.

What are examples of ordinal data?

Ordinal data is data which is placed into some kind of order or scale. (Again, this is easy to remember because ordinal sounds like order). An example of ordinal data is rating happiness on a scale of 1-10. In scale data there is no standardised value for the difference from one score to the next.

How images are stored in MySQL database?
