Data manipulation

In this subject, participants learn the basic techniques of data manipulation in databases. First, they will learn how to enter data using the INSERT statement to insert new records into tables.

In the next step, participants learn how to change existing data using the 'UPDATE' statement to update and correct database content.

Another important part of the subject is the deletion of data. Participants will learn how to use the `DELETE` statement to remove records from tables.

Finally, concepts for ensuring data integrity and the importance of transactions are taught. Participants will learn how to use transactions to perform database operations securely and consistently to ensure data integrity.
