What is the difference between relation and relationship in dbms?

Answer 1

Well, hello there! In the world of databases, a relation refers to a table with rows and columns, where each row represents a record and each column represents a field. On the other hand, a relationship in DBMS defines how the data in one table is related to the data in another table, usually through common fields. It's like painting a beautiful landscape - each element plays a unique role in creating the overall picture. Just remember, in the world of databases, both relations and relationships work together harmoniously to create a meaningful and interconnected system.

Answer 2

In database management systems (DBMS), a relation refers to a table that stores data in rows and columns, following a specific schema or structure. It is a mathematical concept in the relational model of databases. On the other hand, a relationship in DBMS refers to the connection or association between tables based on common fields or keys. Relationships define how data in different tables are related to each other, such as one-to-one, one-to-many, or many-to-many relationships. In essence, a relation is a data structure, while a relationship establishes connections between these data structures in a database.

Answer 3

In a database management system (DBMS), a relation refers to a table that stores data in rows and columns, representing an entity or concept. A relationship, on the other hand, defines the connection between tables based on common fields, such as primary and foreign keys, to establish associations between different entities in the database. Relations are used to store data, while relationships define how data in different tables are related to each other.

Answer 4

Relationship is purely a construct of the er data model.
