Legacy System
Definition: A legacy system is a computer system that has been in existence for a number of years. Often this system is a mainframe system that does not take advantage of new technologies such as client/server.
What This Means: Many education organizations have legacy computer systems that no longer provide the capacity needed for interoperability, multitasking, data-driven decision making and other capacities now considered essential. Moving from a legacy system to a state-of-the-art system often requires many dollars, much staff time, staff development, parallel systems, and other seemingly unconquerable issues to arrive at a more useful and friendly system.
