SQL

Definition

SQL, or Structured Query Language, is a standardized programming language used to manage and manipulate relational databases. It allows users to create, read, update, and delete data within a database, making it essential for bioinformatics and computational biology as these fields heavily rely on large datasets stored in databases for analysis and interpretation of biological information.
