Communications Alternatives for Transparent Data Transfer in Civil Works Computer Systems.

摘要

Although microcomputers are becoming increasingly powerful, there are still applications for which mainframes are better suited. However, the relatively low operational costs and high level of friendliness make the microcomputer a more attractive machine for data input. Distributive processing systems have been created to allow data input at the microcomputer level and processing at the mainframe level. These systems require the computer operator to transfer the file or data from the micro to the mainframe and back; this task often can be both tedious and difficult. In addition to data/file transfer, distributive systems must be able to be updated. One solution to this problem is a transparent communications system. Such a system frees the user from controlling and monitoring the communications link between mainframe and microcomputer. This report describes the development of two transparent communications systems to facilitate use of automated data processing tools used at Civil Works Districts. Included are a distribution (or update) system specific to a single application and a data transfer system.
