SQL Online Courses & Certifications
SQL stands for Structured Query Language. It is a programming language used for managing and manipulating relational databases. SQL allows users to store, retrieve, modify, and delete data from databases. It provides a standard set of commands and syntax for working with databases, making it a widely used language in the field of data management.
SQL operates on a relational database management system (RDBMS), which organizes data into tables consisting of rows and columns. Each table represents an entity or a concept, while the rows contain the actual data records, and the columns define the attributes or properties of those records.
