A programming language that supports relational databases is SQL (Structured Query Language)
Structured Query Language (SQL), is the principal method for communicating with Relational Databases.
A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.
- Tables are utilized for storing data about the items that will be displayed in the database.
- A column in a database contains a specific type of data, whereas a field records the actual value of an attribute.
- The table's rows indicate a collection of linked values for a single item or entity.
Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.

Answer:
Explanation:
Transitive dependency
In this case, we have three fields, where field 2 depends on field 1, and field three depends on field 2.
For example:
Date of birth --> age --> vote
Partial dependency
It is a partial functional dependency if the removal of any attribute Y from X, and the dependency always is valid
For example:
Course and student these tables have a partial dependency, but if we have the field registration date, this date will depend on the course and student completely, we must create another table with the field registration date to remove this complete dependency.
If we remove or update the table registration date, neither course nor student must not change.

Answer:
Option C is the correct answer for the above question
Explanation:
Authentication is used to grant a person to use the system so that no other person can hack the data of the system. It is done by some unique id which is provided to the user of that system. When any person wants to use the system he needs to use that a unique id and sometimes password and some other information to use the system.
The above question asked about the process through which the user of the system grants access to use the system only. So the process is Authentication. hence Option C is correct because it states about the process Authentication while the other is not because--
- Option a states Credibility which is not the process to enter the system.
- Option b states Authorization which is used if the system gives access to the user, not the user can take on its own.
- Option d states Honesty which is not the process to enter the system.
