Relational Algebra and Relational Calculus
Introduction:
Relational algebra and relational calculus are both query languages used for manipulating and retrieving data from relational databases. They provide a formal way to specify queries and operations on the data stored in a relational database.
Relational Algebra:
Relational algebra is a procedural query language. It consists of a set of operations that can be applied to relations or tables in a database. These operations include selection, projection, Cartesian product, join, and set operations like union, intersection, and difference.
Relational Calculus:
Relational calculus, on the other hand, is a non-procedural query language. It is based on mathematical logic and uses mathematical expressions to specify queries. There are two types of relational calculus: tuple calculus and domain calculus.
Procedural vs Non-procedural:
Procedural query languages specify how to retrieve data step by step, while non-procedural query languages specify what data to retrieve without specifying how to retrieve it.
Explanation:
The correct statement is option 'C' - Relational algebra is a procedural query language and relational calculus is a nonprocedural query language.
Relational algebra is procedural because it specifies a sequence of operations to be performed on the relations to obtain the desired result. It provides a set of operations that can be combined in a procedural manner to express complex queries. The operations are performed step by step, and the order of operations is important. Each operation takes one or more input relations and produces a new relation as output.
On the other hand, relational calculus is non-procedural because it specifies what data to retrieve without specifying how to retrieve it. It uses mathematical expressions to define the conditions that must be satisfied by the desired data. The expressions are evaluated to find the tuples or values that satisfy the specified conditions. The order of evaluation is not specified, and the system determines the most efficient way to retrieve the data.
Conclusion:
In conclusion, relational algebra is a procedural query language that specifies the sequence of operations to perform on relations, while relational calculus is a non-procedural query language that specifies the desired data without specifying the retrieval process.
