Relation produced from an E-R model will mostly be in

The relation produced from an E-R (Entity-Relationship) model will mostly be in 3rd Normal Form (3NF).

Here are the steps to explain why:

1. An E-R model, or Entity-Relationship model, is a type of data model that is used to represent entities and their relationships to each other.

2. In the E-R model, data is organized into entities, attributes, and relationships. An entity is a thing or object in the real world that is distinguishable from others. An attribute is a property or characteristic of an entity. A relationship is a way entities are associated with each other.

3. When we convert an E-R model into a relational model (which is the model used in relational databases), each entity and relationship in the E-R model becomes a table in the relational model.

4. The process of converting an E-R model into a relational model involves ensuring that the resulting relational model is in a certain normal form. Normal forms are rules that define certain properties of a relational database. They are used to eliminate or reduce redundancy and dependency of data.

5. The 3rd Normal Form (3NF) is a normal form used in database normalization. 3NF states that a table is in 3NF if it is in 2NF and no column is transitively dependent on the primary key. This means that there is no redundancy of data (every piece of data is stored in only one place) and every non-key attribute is fully functionally dependent on the primary key.

6. Therefore, the relation produced from an E-R model will mostly be in 3rd Normal Form (3NF) because the process of converting an E-R model into a relational model involves ensuring that the resulting relational model is in 3NF.
