FAQs on Introduction to Relational Data Model Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. What is a relational data model in computer science engineering? |  |
Ans. A relational data model in computer science engineering is a way to organize and structure data in a database using tables, where each table represents a relation between entities. This model uses rows and columns to store data in a structured format.
| 2. How is data stored in a relational data model? | |
Ans. In a relational data model, data is stored in tables, with each table containing rows and columns. Each row represents a record, while each column represents a specific attribute or field of the data.
| 3. What are the key components of a relational data model? | |
Ans. The key components of a relational data model include tables, rows, columns, keys, and relationships. Tables store data, rows represent records, columns represent attributes, keys uniquely identify records, and relationships define connections between tables.
| 4. How does the relational data model ensure data integrity? | |
Ans. The relational data model ensures data integrity through the use of keys, constraints, and relationships. Keys uniquely identify records, constraints enforce rules on data values, and relationships maintain consistency between related tables.
| 5. What are the advantages of using a relational data model in computer science engineering? | |
Ans. Some advantages of using a relational data model include data consistency, flexibility, scalability, ease of querying, and support for complex relationships between entities. This model is widely used in database systems for its efficiency and reliability.
