 Hi there! šŸ‘‹ I’m  Ganesh , and welcome to my SQL corner — a place where  data meets curiosity . Introduction to Sub-Languages in SQL SQL (Structured Query Language) is the standard language used to interact with databases — to store, retrieve, and manage data efficiently. To make it easier to perform different types of operations, SQL is divided into sub-languages , each serving a specific purpose. These sub-languages define how users communicate with the database — whether they are creating structures, manipulating data, controlling access, or retrieving information . The main five sub-languages of SQL are: šŸ”¹ DDL (Data Definition Language): Used to define and manage database structures such as tables, schemas, and indexes. (Examples: CREATE, ALTER, DROP) šŸ”¹ DML (Data Manipulation Language): Used to manipulate and modify data stored in tables. (Examples: INSERT, UPDATE, DELETE) šŸ”¹ DQL (Data Query Language): Used to retrieve data from the database for analysis...
