Techopedia explains Relational Database Design RDD Relational databases differ from other databases in their approach to organizing data and performing transactions.
The four stages of an RDD are as follows: Relations and attributes: The various tables and attributes related to each table are identified. The tables represent entities, and the attributes represent the properties of the respective entities. Primary keys: The attribute or set of attributes that help in uniquely identifying a record is identified and assigned as the primary key Relationships: The relationships between the various tables are established with the help of foreign keys.
Foreign keys are attributes occurring in a table that are primary keys of another table.
