What is Trigger?

A trigger is a Database object just like a stored procedure or we can say it is a special kind of Stored procedure which fires after (/before) a specified language event executes. More specifically, it is for the object which is attached to a Table or View or Database schemas for tracking the operations on them. The main difference between a trigger and a stored procedure is that the former is attached to a table or view and is fired only when an INSERT, UPDATE, and/or DELETE occurs, while a stored procedure executes at any time when it is called.

DDL triggers are new to SQL Server 2005. This type of triggers, like regular triggers, fire stored procedures in response to an event. They fire in response to a variety of Data Definition Language (DDL) events. These events are specified by the T-SQL statements that are start with the keywords CREATE, ALTER, and DROP. Certain stored procedures that perform DDL-like operations can also fire this. These are used for administrative tasks like auditing and regulating database operations.

A CLR triggers can be any of the above, e.g. can be a DDL or DML one or can also be an AFTER or INSTEAD OF trigger. Here we need to execute one or more methods written in managed codes that are members of an assembly created in the .Net framework. Again, that assembly must be deployed in SQL Server 2005 using CREATE assembly statement.

I guess write has made a good effort. But there is a room to make it better by giving more example. The best example could be generic Audit trigger using the CLR power.
