Another way is to group them into general categories. Another way of categorizing attack patterns is to group them by a specific technology or type of technology (e.g. database attack patterns, web application attack patterns, network attack patterns, etc. or SQL Server attack patterns, Oracle Attack Patterns, .Net attack patterns, Java attack patterns, etc.)

When one object changes state, an open-ended number of dependent objects should be updated automatically. An object can notify multiple other objects.
