#dataanalytics #dataengineering #datascience SQL Components: DDL, DML, DQL, DCL & TCL Explained In this video, we unpack the 5 key components of SQL — DDL, DML, DQL, DCL, and TCL — and show you exactly what each one does and why you need to know them for data interviews. You’ll learn: What DDL (Data Definition Language) is & how it manages database schema (create, alter, drop) How DML (Data Manipulation Language) lets you insert, update, and delete data The role of DQL (Data Query Language) in retrieving and filtering data (SELECT) How DCL (Data Control Language) handles permissions (GRANT, REVOKE) What TCL (Transaction Control Language) does to commit or rollback changes safely 🔥 Why this matters Understanding these categories is critical if you want to speak fluently with any database — especially in data engineering, analytics, or FAANG-level interviews. Knowing which SQL subset is being asked can drastically improve how you answer. 👍 What Next?
