Data definition is the process of creating a structure for data, including the definition of data types, sizes, and constraints. It is an important part of database design, as it ensures that the data is stored in a consistent and efficient manner.
Data Definition Methods
There are two main methods for data definition: physical and logical.
Physical data definition defines the physical storage of the data, including the file format, data types, and field lengths. Logical data definition defines the logical structure of the data, including the tables, columns, relationships, and constraints.
