Downloading and Micro-Analysis of Databy Janet R. Hopper, Tri-Met, Portland, OR, USA,
Abstract: The microcomputer is ideal for ad hoc analysis while the mainframe is better for storing data. Downloading data from a mainframe computer to a PC takes advantage of the strengths of both and can promote data integrity. The process requires four things: a communications link, communications software, analysis software, and a data file to download. Three applications are discussed which illustrate some of the difficulties to be overcome and some of the pitfalls to avoid. It was found that numeric files are the easiest to download, but it is easier to put the files in the correct format on the mainframe.
