Abstract: This paper describes the design and analysis of database integrity constraints in the national water monitoring capacity building projects. Among them, it briefly introduces the study progress of the database model, the significance of integrity constraints in data management and its implementation method. It analyses the monitoring capacity of national water resources and designs database integrity of building project in detail. It gives the design method of other primary key (entity) integrity constraints and compares the advantages and disadvantages of analysis. It introduces the method of using the relational tables in the database of national water monitoring capacity building projects and illustrates with examples.

Key words: national water resources monitoring capacity building projects; database; integrity constraints
