Either one is functional. It depends on what you are trying to do. Do you want to "log" every single time you use the edit (Insert / Delete) functions? If so, then write the code directly into the department component. Does "AuditTrail" have any function other than logging actions in department? If not, there is probably no need for it to be a separate component. Perhaps it could be a private method inside the department component? >Of course keep in mind that I'm going to have to call the auditTrail >component every time an insert, edit or delete action is made...

If you truly want to apply OO concepts to your design, you may want to look into picking up an Object Oriented design book. If you can find one that is language independent, it would probably be more beneficial than a language-driven book. I saw Ray mentioned the possibility of inheriting the auditTrail CFC in the department CFC. That is probably not an OO solution, since a "department" is not an "auditTrail". This would be an is-a relationship, and is usually implemented using inheritance. A department has an audit trail, though. This is a has-a relationship, which is usually implemented using properties. You could make a property with the type being "auditTrail". However, I am unclear as to how you would access methods of "auditTrail" via the property of department. ( if that makes sense). -- Jeffry Houser | mailto:[EMAIL PROTECTED] Need a Web Developer? Contact me!
