RESUMEN
Objective To discuss how to improve the stability,reliability and security of the core servers of hospital information system.Methods Flaws on security were analyzed objectively in hospital server system adopting 'PC server & local hardisk' scheme.New schemes were put forward including both hot standby scheme based on concentrated storage and full redundancy scheme based on'minicomputer & diskette array'.Results It is proved that the full redundancy scheme is reasonable in theory,and usable in practice.Conclusion The mode of'minicomputer & diskette array' can effectively enhance the stability,reliability and safety of core servers.
RESUMEN
After investigating conditions of 210 seven-year system medical students' extracurricular reading,we discovered that most medical students were rather interested in extracurricular reading,but there existed certain problems in the aspects of the arrangement of time and choice of books etc,which not only lowered the quantity of the student' extracurricular reading,but was disadvantageous to the effective display of the humanities education.Therefore,it was necessary to enhance the seven-year system medical students' extracurricular reading.
RESUMEN
Objective To improve the reliability of the core database system by ameliorating the scheme of the server system architecture. Methods Combined with practice of the hospital informatization, the security and potential hole of the database server system were analyzed and evaluated. Results Aimed to deal with the security hidden-trouble, a mini-server was adopted instead of PC server, while SAN(Storage Area Network) was utilized instead of RAID-5, and mirror copy technique was used to implement the real-time hot copy of the data. Conclusion Consequently the reliability of the system has been greatly improved.
