Problems of Interpretation and Representation in the Computerization of a Printed Reference Work on Materials Data

Source

Problems encountered during a recently completed computerization project of a massive reference work (MilHdbk 5E), capturing approximately 300 tables and 1000 graphs, are identified and their solution described. Some of these problems appeared at the data entry stage, others during the process of validation of the completeness and homogeneity of the final 18,000 database records. The major categories of problems identified and illustrated comprise:inconsistencies and ambiguities arising from excessive compression in the printed form, explicit linkages which are required between exhibits for the computerized version, incomplete linkages, and other errors and ambiguities. In addressing these problems, the computer itself is used insofar as possible. First, to identify the existence of the problem, and second, to apply constraints, perform linkages, implement denormalization routines, etc. to produce the desired set of searchable records used to form the database.
