데이터 모델링을 위한 관계 도출에 관한 연구

Abstract

As the business of the company becomes more complicated, the construction of the information system becomes a necessity, and the database that becomes the basis of the information system becomes important. Construction the right database starts from database design, and There have been many studies on the procedure for elicit design factors. However, there are problems in the communication due to the lack of representation and elicitation procedure among the database design elements, and there is a difficulty for the novice or unskilled persons to carry out the design procedure. In order to solve this problem, this study presented a clear and detailed definition of the viewpoint and the expression of the relationship and the process of elicitation the relationship in the modeling process for database design. The definition of a relationship should be changed by establishing a relationship in terms of business and correspond to the relationship of data, and During the modeling process, the relations hip elements should be elicited from the entity and attribute elicitation procedures, and the detailed business rules should be applied to determine the relationship. We will be able to solve the problems of communication and design difficulties for novice and unskilled persons by comparing, analyzing the procedures presented in this study, and the methods presented in the previous research from various perspectives . Using the elicited relationships, we will be able to proceed with logical model design and physical model design to be performed later.
