You will also learn how to work with multiple tasks as a transaction. In This Course You will: • Construct advanced queries and apply them to data. • Use nested queries to generate query output. • Manipulate table data by inserting, modifying, and deleting data. • Manipulate the structure of tables. • Work with views to present data. • Index data to improve querying efficiency. • Manage database transactions.
