HSPD Limitations 4:

- a database, not an information system.  The system cannot track
the decision process of each application, and as a consequence,
cannot become a collection of annotated case studies that convey
a sense of the context of preservation management decisions.  The
system communicates no sense of hierarchical relationships to the
user, nor of the relationship between information fields.  The
DBMS structure presents an inherent difficulty in coherently and
comprehensively communicating an understanding of the complete
data structure and the relationships that exist between the
records and fields which constitute the database.

- database queries are only as accurate and thorough as the
ability of the user to specify the appropriate search criteria. 
Research has demonstrated that even in the hands of professional
users (lawyers), a database system of legal references and court
rulings provided users an average of less than 22% of the
information which may have been relevant to their query (Larson,
1988).  The user of a DBMS remains unaware of what additional
information, relevant or related to that already retrieved, may
be available in the system.
