R2 = {(5, 4), (4, 3), (3, 2), (2, 1), (1,5)}. Which of the following statements are correct? Tick the corresponding boxes. R₁ is reflexive but R2 is not. R₁ is transitive. R₂ is transitive, because if you draw the digraph of the relation you can follow a ro through all the elements of the set. R₁ is antisymmetric. R2 is antisymmetric.
Concepts in Designing Database
A database design is the process of data organization based on a database model. The process deals with identifying what data should be stored in a database and how data elements relate to each other.
Entity Relationship Diagram
Complex real-world applications call for large volumes of data. Therefore, it is necessary to build a great database to store data safely and coherently. The ER data model aids in the process of database design. It helps outline the structure of an organization’s database by understanding the real-world interactions of objects related to the data. For example, if a school is tasked to store student information, then analyzing the correlation between the students, subjects, and teachers would help identify how the data needs to be stored.

![Let R₁ and R₂ be the following relations on the set {1, 2, 3, 4, 5}.
R₁ = {(1, 1), (2, 2), (3, 3), (2, 1), (3, 1)}
R₂ = {(5, 4), (4,3), (3, 2), (2, 1), (1,5)}.
