An action or occurrence detected by a program. Events can be user actions, such as clicking a mouse button or pressing a key, or system occurrences, such as running out of memory. Most modern applications, particularly those that run in Macintosh and Windows environments, are said to be event-driven, because they are designed to respond to events.
A database event can be anything relative to the rows in a table or values in fields. Coordinated and monitored by the Firebird/InterBase® Event Manager.
