Session Overview:
In this recorded session, we will continue from the previous class and dive deeper into the architecture of a Data Warehouse. We will cover key SQL commands related to data management and control, including:

DML (Data Manipulation Language) SQL Commands: These commands are used to manipulate data within the Data Warehouse. Common DML SQL commands include SELECT, INSERT, UPDATE, and DELETE, which allow you to retrieve, add, modify, and remove data.

DCL (Data Control Language) SQL Commands: These SQL commands manage permissions and access control for the data in the Data Warehouse. Examples of DCL SQL commands are GRANT (to assign privileges) and REVOKE (to remove privileges).

TCL (Transaction Control Language) SQL Commands: These SQL commands help manage transactions and ensure data integrity. Key TCL SQL commands include COMMIT (to save changes), ROLLBACK (to undo changes), and SAVEPOINT (to set a rollback point).

This session will provide a foundational understanding of how these SQL commands are applied and understanding of Data Warehouse architecture
