| Paper based on the national mineral resources potential evaluation project in-depth describes the design, development process of management system. The project calls for the full application of computer and GIS technology. For this purpose, geological professionals and computer staff who participate in the project work together to design the data model of national mineral resources potential evaluation used object-oriented technology. Data model describes the relationship between data, standardize format and shape of the data and ensure that the data submitted can be consistent, complete and accurate. Using data model may manage project in an order. The design of management system integrates the complex information of the data model and makes users more effective.In the paper, author in-depth analyses the content of the data model. Using UML describe system need analysis, functional module design, system static model and dynamic model. The MVC design pattern is common to split an application into separate layers: Model, View, and Controller. This three-tier design pattern makes Maintenance procedures easy. It is always used in software engineering. DTO in the system is used to transfer data between software application subsystems. DTO can hold all the data for the call, so that to accelerate the speed of data transmission. System accesses System Access background database using Data Access Object(DAO). The Data Access Object classes can provide access to a particular data resource without coupling the resource's API to the business logic, separate a data interface from its data access mechanisms. In the end , Implementation of system based on .Net platform using C# programming language. The system can be used to manage map list, layer list, database list, basis of information, table structure definition and users information.After several tests, the management system will be used by geological staffs who participate in the national mineral resources potential evaluation project.
