Database indexes are primarily used to enhance database performance. The key field(s) for the index is specified as a column name(s). Multiple fields can be specified if the index method supports multi-column indexes.
Using Index Manager you can create a new index, edit or drop the existing one. On the right side of the dialog the index properties are visible. The primary key index will be shown with a key icon.
A trigger is a specification that the database should automatically execute a particular feature whenever a certain type of operation is performed. A trigger can be defined to execute before or after an INSERT, UPDATE, or DELETE operation, either once per modified row, or once per SQL statement. If a trigger event occurs, the database engine executes the trigger.
Trigger Manager allows you to manage table triggers. You can create or delete the triggers or see their properties.
