Corrigenda: “The Logical Record Access Approach to Database Design”

Database management systems have evolved to the point of general acceptance and wide application; however a major problem still facmg the user is the effective utihzatlon of these systems. Important to achmving effective database usability and responsiveness is the design of the database. This paper presents a practmal stepwlse database design methodology that derives a DBMS-processable database structure from a set of user information and processing requirements Although the methodology emphasizes the logical design step, the activities of reqmrements analysis and physmal design are also addressed. The methodology is illustrated wtth a detailed example Performance trade-offs among multiple users of a single integrated database are considered, and the relationship between short-term design and design for flexibility to changing reqmrements IS discussed. Many steps m the database design process can be assisted with proper use of computer modehng techniques and other tools, such as requirements analysis software. The example design problem and its solution steps serve to point out when and where current technology can be effectively used
