摘要

The concept of an external views system (EVS) for a database management system (DBMS) was introduced a long time ago. The idea is to allow a user to perceive data in the form most convenient for him. Thus the user can focus on those data and those relationships that are of some interest, ignoring all others.Few commercial DBMS support the above concept to even a limited extent. We have designed and implemented our EVS on top of the TOTAL (Cincom) database system.The particular requirements of the medical research environment allowed us to restrict the operations on views to retrieval only and thus helped to avoid numerous problems connected with update operations via views. Using our EVS-system casual users can access a view with little or no instruction.
