Model-- Engineering Data.
Abstract
The acquisition, acceptance, storage, management, distribution and use of data for the logistic support of weapon systems has long been a challenge for the member agencies of the Department of Defense (DoD). One of the biggest problems is that of obtaining and maintaining quality data. This problem has been recognized for many years by the DoD agencies and has been addressed by improving the data storage medium in terms of resolution, durability, and storage density. Micrographic media such as aperture cards were introduced to successfully reduce the data storage and distribution problems associated with the use of hard copy. As weapon system technology advanced and complexity increased, the requirements for more support data increased. It is reported that there are now some 200 million source aperture cards in use by the DoD agencies. The manual storage, indexing, and management of the growing data base have again become a problem. More importantly, the quality of the data has suffered due to increased handiing and duplication of the aperture cards. Technological advances of the last - two decades in processing speed and power, mass storage speed and capacity, image processing, image scanners and image software have provided economic means of solving or at least minimizing many of these problems. The DoD authorized the procurement of repository image management systems in the early 1980s to apply such technological advances toward the solution of the data management problems. A joint Army/Air Force procurement of the Digital Storage and Retrieval Engineering Data System (DSREDS)/Engineering Data Computer Assisted Retrieval System (EDCARS) resulted in the installation of 12 data repository sites. In late 1989,- the Navy installed its first Engineering Data Management Information and Control System (EDMICS) repository system. DSREDS/EDCARS and now EDMICS are all a
