VITAL provides a way of building information systems constructed from generalized modules that can be reused and shared.It specifies how to construct and provide interfaces for these modules. A cornerstone of Apple’s client/server architecture is Data Access Language (DAL). DAL consists of software components for the client and the server (Macintosh System 7 includes the client component, DOS and Windows clients are sold separately). DAL sits between the client and server components.
