What programming language supports relational databases?
WINSTONCH [101]

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.

Consider the following statements regarding computer programs A - Variables can contain different values at different times.B -
jeka94

Answer:

The answer is: Only A is correct.

Explanation:

Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.

In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.

Hence, the answer is: Only A is correct.
