| Abstract: | In order to strengthen the monitoring and management for dynamic information of ancient and famous trees,it is necessary to use the database and the current mainstream programming language to develop appropriate management information system.The attribute database of ancient and famous trees is designed,and most importantly,the design process of three main triggers is described.Through the application of the trigger,the historical data record is automatically saved about the growth process and conservation information of ancient and famous trees,and the death information is also automatically updated.The application of the trigger not only ensures the consistency of data,but also reduces the workload of programming applications. |
