FAQs on Exercises based on Relational Model – Part 1 Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. What is the Relational Model in computer science? |  |
Ans. The Relational Model in computer science is a way of structuring data using relations, which are essentially tables with rows and columns. It is a widely-used method for organizing and querying data in databases.
| 2. What are the key components of the Relational Model? | |
Ans. The key components of the Relational Model include relations (tables), attributes (columns), tuples (rows), keys (unique identifiers), and constraints (rules to maintain data integrity).
| 3. How is data represented in the Relational Model? | |
Ans. Data in the Relational Model is represented in tabular form, with each row representing a distinct record and each column representing a specific attribute or field of that record. This tabular representation allows for easy querying and manipulation of data.
| 4. What are some advantages of using the Relational Model for data storage and retrieval? | |
Ans. Some advantages of using the Relational Model include data integrity through constraints, ease of querying using SQL (Structured Query Language), flexibility in data manipulation, scalability for large datasets, and normalization to reduce redundancy.
| 5. How does the Relational Model differ from other data models like the hierarchical or network model? | |
Ans. The Relational Model differs from hierarchical and network models in that it uses tables to represent data rather than tree-like or graph-like structures. It also enforces data integrity through constraints and allows for more flexible querying through SQL.
