Data Types in Oracle | Oracle SQL fundamentals

Each value which is manipulated by #Oracle #Database has a data type. The data type of a value associates a fixed set of properties with the value.
Using these properties Oracle treats values of one data type differently from values of another. For example, you can add values of #NUMBER data type, but not values of #CHAR data type.
Oracle Database provides a number of built-in data types as well as several categories for user-defined types that can be used as data types.
