데이터 모델링을 위한 업무기반 엔터티 도출 절차

Abstract

As the frame of the information system, data model forms one of two important axes of the information system along with process model. The core components of data model are entity, attribute and relation, among which entity is the most basic component of data model. Without clear deduction of entity, entire data model becomes vague. This study mainly focused on entity deduction. With the existing method of deducing entity, it is very difficult for a novice to use the method because it is heavily dependent upon designer's experience and work knowledge without a clear process. For the purpose of providing assistance in solving this issue, this study proposes a task-based entity deduction process for deducing entity through a systematic process for target business that have been deduced. In addition, it was designed to apply the proposed process to virtual task for undergraduate students without data modeling experience. Using a similarity test for the entities deduced by students and answer sheet, the proposed process was verified through which it was confirmed that deduced entities were very similar to the answer sheet. Accordingly, it was confirmed that entities similar to answer sheet can be deduced even by novices without data modeling experience by applying the process proposed in this study to unfamiliar tasks.
