In this paper, the author has identified several functions required in order to be able to use a conventional relational database system in support of management of instructional materials, test items, educational objectives and learner's response data. Based upon this, he has also completed a prototype instructional design and evaluation system. Conventional relational database systems, commercially available for use with personal computers, can be effective in the processing of learner data and retrieval of test items. They are at a disadvantage, however, in practical instructional design and evaluation applications. Two concepts are introduced as basic solutions to this problem : 1) The interface provides a flexible visual hierarchial schema based upon the diverse needs of the users. 2) Relationships among sets of corresponding tables may be retrieved through the use of item names and values as keys. As a result of these new capabilities, integrative management of instructional materials and learner data is feasible even though the two areas are maintained separately. Other advantages include the capability to edit and publish lists of objectives and to prescribe questions for individual learners.
