Abstract

The database that is characterized by real-time accessibility and concurrent sharing by multiple users is indispensable to large population-based clinical research. Because initial design determines the effectiveness of database, delicate and complete development is required. Understanding of research and communication between user and programmer is the first step of database development. According to the purpose of research item, the entity and attribute are determined in detail that can minimize data redundancy and maintain data consistency. The programmer should analyses the demand of final user before logical design. Also the user should provide unit information and old data to programmer. After interaction between programmer and user, the database system flow is designed by real organizational unit flow diagram. The user's view is classified by subtitle and grouped by similar data. The flow of view is concordant with real flow diagram. The active participation of final user in early phase is essential for successful development of database.
