With more than 350,000 copies in print, this classic is the most comprehensive learning tool available for understanding and programming the IBM PC family of computers. Now revised and expanded, it has become even more indispensable.
This practical guide to microcomputer-based data management systems discusses design methods, software selection, and the strengths and weaknesses of major current product offerings. Step-by-step, readers are led through all phases of the problem solving process. The book carefully describes what a data management system is, what it can do, and what it cannot do. It introduces such basic concepts as fields, records and files, input screens and reports, and data manipulation operation. A design methodology is provided which includes specific examples and worksheets for simpler applications (such as mailing lists, check registers, etc.). More advanced topics are presented as well - including multi-file applications, data base programming languages (data manipulation languages), and the organization of more complicated data bases.
Here is another contribution in the continuing series on Computer Methods in the Geosciences. As its title suggests, this volume will be of interest to explorational geochemists who want to analyze their own data on a personal computer (PC). To make it easy for the user, the programs and two trial data sets are provided on the accompanying diskettes. And, by supplying the diskettes, another first is accom plished for the series: instant involvement and interaction for the user. Although other books in the series have provided listings of computer pro grams, Exploration-Geochemical Data Analysis with the IBM PC is the first to supply diskettes. The diskettes, along with the instructions outlined in the text, eliminate the bother (and errors) of pu tting the programs in man ually. The suite of programs for handling and sorting data files; computing and displaying summary statistics; and working with logarithms, geochemical thresholds, and regression - will give geochemists a good repertoire for geochemical exploration data analysis. The diskettes are easy to use and have been tested thoroughly.
Revised and enlarged to be the most comprehensive learning tool for understanding and programming the IMB PC's, this guide features thorough explanations of MS-DOS, PC-DOS and BASIC programming, memory, graphics, games, file-handling, sound and flowcharts.
