Computer applications, both hardware and software, which have been inherited through previous acquisition and installation. Most often, these systems run business applications that are not integrated with each other. Newer systems which stress open design and distributed processing capacity are gradually replacing such systems.
Hardware and software applications in which a company has already invested considerable time and money. Legacy systems typically perform critical operations in companies for many years even though they may no longer use state-of-the-art technology. Replacing legacy systems can be disruptive and therefore requires careful planning and appropriate migration support from the manufacturer.
Existing applications and repositories of data; often large and containing years' worth of information. Can be mainframe, midrange, or network based.
slang expression referrings to an older information system currently in use by an enterprise.
Computer systems used by businesses that are almost impossible to replace. These can be PC based systems
Those systems that were designed using hardware and software systems that are rapidly becoming obsolete or are no longer supported by their vendors. Legacy information systems resists modification and change. Legacy records rely on these systems.
Usually mainframes and/or minicomputers with proprietary operating systems, typically old, for which off-the-shelf software may not be available. These systems frequently contain substantial data to which the organization needs to retain access. May require computer-specific APIs to enable CTI. (See also Host.)
A term commonly used to refer to existing computers systems and applications with which new systems or applications must exchange information.
Older computing technology used by an organization over time. Legacy systems perform business-critical functions and can be integrated with newer systems.
Information systems that have been in use for some time.
Programs or systems that an organization inherits due to mergers and acquisitions or previous installations.
Computer systems or application programs which are outdated and incompatible with other systems, but are too costly to replace or redesign. They are often large, intimidating, and difficult to modify.
Essentially a legacy system is an application or a set of applications crucial to the day-to-day operations of the company. The company has often heavily invested in the system and it has high usage (thousands of transactions per day). They are often based on old database technology with text-based user interfaces. Synthesys provides access to the data held in these applications, displaying the information to the agent in the Synthesys front-end.
Older computer systems that must be integrated with newer software/hardware.
Previous generation/version information technology architectures and their contents whose dysfunctionalities need to be overcome in deploying new generation/version information technology.
