Building on Sessions 1 and 2, we'll add constraints to data, store SELECT statements in views, and add triggers.
This course is the foundation for the Microsoft Certificate 70-461: "Querying Microsoft SQL Server 2012".
In Session 1, we learned all about dates, strings and number data types, and in Session 2 we constructed SELECT queries using SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY, and JOINing multiple tables together.
We'll now use that data to create views, which enable us to store these SELECT queries for future use, and triggers, which allow for code to be automatically run when INSERTing, DELETEing or UPDATEing data.
We'll look at the database that we developed in session 2, and see what is wrong with it. We'll add some constraints, such as UNIQUE, CHECK, PRIMARY KEY and FOREIGN KEY constraints, to stop erroneous data from being added some data. By doing this, we will complete objectives 2, 3, 4 and 5 from the 70-461 exam.
