In This Issue

Office workers who bravely face that ever-growing mountain of paper will tell you that keeping track of information becomes more difficult daily. How to impose order? As Robert Tinney's cover suggests, the answer is something like an electronic file cabinet. This month's theme concerns the problems of data management. Joel Neely and Steve Stewart will get you started with "Fundamentals of Relational Data Organization." From there you can move on to "Data-Base Management Systems: Powerful Newcomers to Microcomputers," "A Survey of Data-Base Management Systems for Microcomputers," and "PDO: A Data Manager for Beginners." "DIF: A Format for Data Exchange between Applications Programs" presents a strong argument for standardization of data formats. Apple II file-management systems are reviewed. And you can learn how to write with your data-base management system. Is spelling a nightmare? If so, you'll be interested in Phil Lemmons' review of the five major CP/M spelling-correction programs. Of course, there's Ciarcia's Circuit Cellar, BYTELINES, and our other regular features, too.
