| 1. What is Relational Algebra? |  |
Ans. Relational Algebra is a procedural query language used to query the relational database management systems. It provides a theoretical foundation for relational databases and allows users to retrieve data from tables in a systematic way.
| 2. What are the basic operations in Relational Algebra? | |
Ans. The basic operations in Relational Algebra include Selection, Projection, Union, Set Difference, Cartesian Product, and Join. These operations are used to manipulate and retrieve data from relational databases.
| 3. How is Relational Algebra different from SQL? | |
Ans. Relational Algebra is a theoretical language used to query databases, while SQL (Structured Query Language) is a practical language used in implementing and managing databases. Relational Algebra focuses on the mathematical operations on tables, while SQL focuses on the manipulation of data.
| 4. What are the advantages of using Relational Algebra? | |
Ans. Some advantages of using Relational Algebra include its simplicity, clarity, and theoretical foundation. It provides a formal way to query databases, allowing users to manipulate data in a systematic and efficient manner.
| 5. Can Relational Algebra be used for complex queries? | |
Ans. Yes, Relational Algebra can be used for complex queries by combining multiple operations such as Selection, Projection, Join, and Set Operations. Users can create intricate queries to retrieve specific data from relational databases.
