What are logical tablesthey are structurally similar to the table on which the trigger is defined?

Logical tables are more than likely "views". Views are created to pull data from one or more tables based on what the data reporting needs are. That way you do not have to create a query each time you want the same data.

Triggers are events that are fired upon the condition they are coded by. An "insert" trigger may look for a certain type of data to be inserted into the database.

Views and triggers perform separate functions in a database.
