Information is described by the entity relationship model as consisting of a set of entities, a set of relationships, and an attribute. The E-R Model makes it simpler to understand how entities are related. The cardinalities of mapping are defined by the E-R model.
Relational Model: It depicts the collection of tables and their connections. Information is described by the Relational Model as a domain, attributes, and tuples in a table. In contrast, it is more difficult to establish a relationship between tables in the relational model. Cardinal mapping is not depicted in the Relational Model. In complex databases and data warehouses, data from a domain must be introduced across multiple tables to maintain a relationship between them. The concept of referential integrity comes from the theory of foreign keys.
