Browsing in Data Bases.
Abstract
This report considers the tasks of trying to find similarities between the causes of the crashes of several aircraft of a common type, the causes or early warning signs for various diseases, the characteristics of stocks with high growth potential or advanced warnings of severe weather conditions. All of these tasks require a large amount of data and valuable time spent sifting through the data. A brownsing computer system could also perform these tasks. This thesis examines one possible organization for a browsing system containing models and heuristics. The models describe the organization of the data base and the objects from which the data was gathered. The heuristics provide knowledge on important features which might exist within the data base and techniques for locating these features. An implementation of the organization was performed using a data base describing maintenances performed on Navy aircraft. This computer system, BROWSER, attempts to find recurring time-sequences of maintenances and major differences in the types of maintenances performed on different groups of aircraft. The user is then notified of these discoveries in the hope that changes will be made to improve the performance of the aircraft.
