  Home  Client Server Architecture

⟩ What is APPLEs VITAL architecture?

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.

This approach allows varied clients to communicate with

many different servers. With DAL, a change in the DBMS

does not affect the front-end;

it simply requires the appropriate DAL link.
