A legacy technology is an old strategy, system, computer system, or application program that can be applied to it, usually required as it is still running for the user, yet also fresh technology or more efficient methods of implementation of the project will be available soon. A legacy technologies, processes and terminology that are not applicable to current circumstances and can block or baffle the benefit of the method or methods used.
organization committed to the cause of an outdated technology, such as:
The technology works satisfactorily, and The owner keeps no reason for the cost of design changes ist.Die system or replacement of prohibited sign as it is good, solid and / or Composite.Umschulung a new technology more expensive confused time and money equated with the expected substantial change getting it. The technology should be close to the fixed connection, so that it took the service, and the cost of designing a new technology that has equal access is high. Exemplifications incorporate the technology into customer bank accounts, computer reservation systems, air traffic management, department of energy (power grids), nuclear power plants, military and defense integration technologies such as database Tops abzudecken.Die method works, The technology is not sufficiently well executed. This type of position can happen if the designers of the technology company and the organization has not provided any documentation or fully authenticated users desorientiert.Der expected that the technology is easy to replace if it gets important
legacy technology as a potential problem for some software engineers for various reasons:
legacy technologies often wear sets (and generally dumb) hardware and additional components for the computer can be a very growingly difficult legacy technology bekommen.Wenn antediluvian running the hardware only, the cost of keeping the technology may eventually outweigh the costs of changes of both hardware and software to generate more or less emulation or backward compatibility, the software grants to new hardware technologies can laufen.Diese difficult to maintain, improve, and prosper because it is a universal shortage implementation of the technology, the employees who are experts here, deferred or disremembered what you learn about them here, and employees recorded in the area, then he is "legacy" never heard about it in the first layman. It will be rejected by a lack or loss of documents. A territorial kicked airline CEO in 2004 due to losses of a prehistoric technology legacy programming crew to a restriction may not be for anyone in the organization known as geworben.Legacy technology earlier involvement in the operating system or application lack of security Dapples committed or used. Conformations may also be the cause of production problems with security. These problems may be the technology of the legacy of opportunity for attackers or insiders gelegt.Konsolidierung down well versed in the new technology can also be difficult for new software can not use the same system. This type of bridge hardware and software, are useful because such technologies democratically transformed simultaneously tend not contradict technology formulated at different times, such as the lack of a high demand for them and The lack of appropriate honor a great market economies of scale, while more or less of this 'glue' will not take formulated by the seller and fond of some legacy technologies.
