FAQs on Relational Algebra Sets Unions & Join Operators Video Lecture - Question Bank for GATE Computer Science Engineering - Computer Science Engineering (CSE)
| 1. What is relational algebra? |  |
Relational algebra is a procedural query language used to retrieve and manipulate data stored in relational databases. It consists of a set of operations that can be applied to relations (tables) to perform queries, such as selection, projection, union, intersection, and join.
| 2. What are set operations in relational algebra? | |
Set operations in relational algebra are used to combine the tuples of two relations based on set theory principles. The most common set operations include union, intersection, and difference. Union combines the tuples of two relations and eliminates duplicates, intersection returns the common tuples between two relations, and difference returns the tuples present in one relation but not in the other.
| 3. What is the union operator in relational algebra? | |
The union operator in relational algebra combines the tuples of two relations and returns a new relation that contains all the tuples from both relations. It eliminates any duplicate tuples from the result. The union operator is denoted by the symbol ∪.
| 4. What is the join operator in relational algebra? | |
The join operator in relational algebra combines the tuples of two relations based on a common attribute or condition. It returns a new relation that contains all the tuples from both relations that satisfy the join condition. There are different types of join operators, such as inner join, outer join, and natural join, each with its own rules for combining tuples.
| 5. How are join operators different from set operations in relational algebra? | |
Join operators in relational algebra are used to combine tuples from two relations based on a specific condition, such as a common attribute. Set operations, on the other hand, are used to combine tuples from two relations based on set theory principles, without considering any specific condition. Join operations result in a new relation that may have additional attributes, while set operations only consider the existing attributes of the relations being combined.
