component architecture <programming> A notion in {object-oriented} programming where "components" of a program are completely generic. Instead of having a specialised set of {methods} and {fields} they have generic methods through which the component can advertise the functionality it supports to the system into which it is loaded. This enables completely {dynamic loading} of {objects}. {JavaBeans} is an example of a component architecture. See also {design pattern}. (1997-11-20)
