SQL (Structured Query Language) is a standardized programming language used for communication with relational databases.
Purpose of SQL:
- SQL enables programmers to interact with databases efficiently.
- It allows you to perform tasks such as querying data, updating records, defining structures, and managing data within a database system.
Key Points:
- Structured Query Language: SQL provides a set of commands and syntax for working with data.
- Database Communication: It allows you to retrieve, insert, update, and delete data from relational databases.
- Common Usage: SQL is widely used by applications, websites, and organizations to manage data.
Pronunciation:
- SQL is usually pronounced like the word “sequel.”
- Some people pronounce it as an acronym, saying all three letters: “ess-que-el.”
Is SQL a Programming Language?:
- Yes, SQL is indeed a programming language.
- It offers features like looping, logic directives, variables, and more.
- However, it differs from languages like Java or C++ (which are third-generation languages) because SQL is considered a fourth-generation language (4GL).
