Relational Database Model
Data models conceptualize the designing and structuring of a database.
They define how data will be stored, accessed, and updated in a database management system.
Relational Model:
- Data is organized in two-dimensional tables and the relationship is maintained by storing a common field.
- The basic structure of the relational model is the tables.
- All the information related to a particular type is stored in rows of that table.
- Each row in relation contains a unique value.
- Each column in a relation contains values from the same domain
- Each row in the table is called a tuple.
