Relational model in DBMSIn relational model, the data and relationships are represented by collection of inter-related tables. Each table is a group of column and rows, where column represents attribute of an entity and rows represents records.Sample relationship Model : Student table with 3 columns and four records.Table: Student Stu_Id Stu_Name Stu_Age111 Ashish 23123 Saurav 22169 Lester 24 234 Lou 26Stu_Id Course_Id Course_Name111 C01 Science111 C02 DBMS169 C22 Java169 C39 Computer NetworksHere Stu_Id, Stu_Name & Stu_Age are attributes of table Student and Stu_Id, Course_Id & Course_Name are attributes of table Course. The rows with values are the records (commonly known as tuples).
