Developed around the technology of the Apple duodisk drive, five and one-fourth inch floppy disks, and the 1.3 version of the AppleWorks program, this manual is designed for use as a "how to" training device in developing database files. The guide is meant to be used with Apple IIe or IIGS computers which have a duodisk or two disk drives and an 80 column card installed; other versions of the AppleWorks program; and the smaller disk drives presently available on the market. Necessary items and skills required by potential users of the manual are specified, and how to build and modify a database file is explained. It is noted that additional guidance in the construction of a database is available in the AppleWorks manual which accompanies the purchase of the program, or from manuals available in bookstores.
