Discusses data acquisition systems for biologists, considering: (1) input; (2) output; (3) controllers; (4) software for data acquisition; and (5) programing languages. Also discusses several biochemical databases, including those storing data on protein sequences and on chemical structures in two-dimensional form (together with biological testing…

Last article in a series reviews online databases in fields of astronomy, earth sciences (geology, oceanography, other geosciences), and materials science (interdisciplinary subject encompassing ceramics, polymers, metals, glasses, etc.), noting coverage and search strategies. A table of 28 databases citing major subjects, producers, and starting…

Describes a procedure for using commonly available database management systems to produce indexes on microcomputers. Production steps discussed include creation of the database, data entry, database sort, formatting, and editing. (Author/MBR)

Describes statistical techniques for analyzing data collected by management information systems. The techniques permit comparison of the performance of service providers and are applicable to databases developed for all service systems where human beings are being provided total care.
