Project – DMLTopics – In this project you will learn about the Data Manipulation Language (DML), understand all about the DML triggers which are a special type of stored procedures that are automatically executed when DML operation is performed. You will learn about the various DML operations like INSERT, UPDATE, or DELETE which when fired on a Table or View can activate a DML Trigger. This project involves working with database and application Triggers, deploying the Triggers for various business applications and testing of the DML Triggers.
