Objective To discuss the ideas and specific implementation steps of Oracle database upgrading.Methods By using the EXP and IMP which are provided by the Oracle database,import and export of entire database are implemented and complete database upgrading.Results The database is upgraded form Oracle 8i to Oracle 10g,which is the foundation of our hospital follow-up implementation of PACS and RAC technology.Conclusion Because the environment of practical application is different and complex,the Oracle database must test before the upgrading;the appropriate parameters are set according to different front-end application environment,and then enhance server performance significantly.

Objective To design a support system based on HIS for enhancing hospital managers' ability in making decision. Methods Through modeling and programming for the system,we integrate,classify and analyze the date from outside and inside. Results Managers can analyze the outcome using multi-dimensions online tools. This system brings the convenience to managers,and enhances scientific and timely decision. Conclusion We put forward the basic method for hospital support system,which is the foundation for future research.
