Remote job entry
（重定向自RJE）
Remote job entry is the procedure for sending requests for data processing tasks or 'jobs' to mainframe computers from remote workstations, and by extension the process of receiving the output from such tasks at a remote workstation.
The RJE workstation is called a remote because it usually is located some distance from the host computer. The workstation connects to the host through a modem or local area network (LAN). Today this is known as the client–server model, and RJE is an early form of a request–response architecture.
