This thesis addresses the problem of small user groups
being forced to use input data collected and processel by
sources outside their span of control. Specifically, the
use of an active data dictionary to locally validate such
input data is examined. The thesis proceeds from a general
review of data validation techniques and criteria, through
an examination of data dictionaries, to an illustration cf
how an active data dictionary can be configured to act as a
"data filter" for input data.
Key initial planning and design steps are set forth,
including requirements analysis, data definition, and
initial logical design. A checklist of questions to answer
during each of these activities is included.
The concepts discussed in the paper are then applied to
a specific case (DCSPLANS Branch, a.S. Army Military
Personnel Center, Alexandria, VA) resulting in a "data
filter" structure diagram that is tailored to the DCSPLANS'
environment and their unique validation needs.
