Abstract: Data abstraction and structure design are the foundation of application system construction, which are related to the practicability, scalability and stability of the system. Before the application system is put into service, the necessary work flow is to initialize the system, create an instance of the management objects for the system, and then applications are implemented. This paper, taking dam safety monitoring and management information system - iDam as an example, elaborates its basic data structure design and implementation of initialization, for reference.

Key words: dam safety, safety monitoring, initialization, data structure

摘要： 数据抽象与结构设计是应用系统建设的基础，关系到系统的实用性、可扩展性和稳定性。应用系统在投入运行前，通常需要进行系统初始化，通过系统构建其管理对象的实例，然后才能开展相关的应用。以iDam大坝安全监测管理信息系统为例，详细阐述其基础数据结构设计与初始化应用。
