What determines the type of data that can be stored in a column on an oracle table?

The type of data that can be stored in a column of an Oracle table is determined by the column's data type, which is defined when the table is created. Oracle supports various data types, including numeric, character, date, and binary types, each with specific characteristics and constraints. Additionally, constraints like NOT NULL, UNIQUE, and CHECK can further define the permissible values for that column. Ultimately, the chosen data type and constraints ensure data integrity and optimize storage efficiency.
