Design And Implementation Of Hospital Information System Based On Struts And Hibernate

With the fast development of the information technology, the computer technology has seeped through all profession in society, and the hospital also starts to apply the computer system in each aspect. With the deep reforming of the medical care system, the informatization degree to the hospital is more and more high. In order to improve the hospital synthesis service level, enhance the working efficiency and financial management, increase the transparency of service, extremely satisfy the patient need, the hospital information system is recognized by the international academic circles as the important branch of Medical Informatics. HIS occupies very important position in medical treatment information modernized course , whose studies and builds having accepted home and abroad to take seriously. HIS is that the computer network system passing the local area network interconnection accomplishes the administration to the outpatient and the inpatient.Although the HIS in domestic has already developed, but in this developing process, the decided product pattern and the user custom-made demand is the contradiction which solved with difficulty, for the difference in management style and not having a unified standard when developing software. In order to resolve this contradiction, HIS facial hospital exploitation adopt the J2EE technology. J2EE (Java 2 Platform , Enterprise Edition) debuted by the SUN company is a kind of multilayer structure enterprise level standard truss, which works out one by one commonly from Sun company leader and get the industrial standard approving broadly.At the same time, along with more and more many developers taking J2EETM server as the first choice platform of server application, developer experience as well as obtains may the reusedesign be more and more important. Introducing the reasonable design pattern may help us to find the solution to the same or similar question; and the frame may enhance the development speed in the very big procedure and reduce thedevelopment cost.The Struts frame most is earlier than May, 2000 which published as the Jakarta project constituent, the Jakarta project organizes the operation by the Apache fund. The project establishment hope improve and enhance Java ServerPages, Servlet, the label store house as well as the object-oriented technical level. The Jakarta project has very many successful parts, for example product and so on Tomcat, Cactus as well as Log4. More over Struts opens the source code project, its prospect is limitless.In the developing of HIS facial hospital, for the very good management, the processing service level and the model relations, increased the data lasting level between the service level and the model, the data lasting level realization had the many kinds of methods: Directly useing the SQL/JDBC manual code to continue the level, the operation quite is simple, easy to operate, but the correlation big project says, when demand change must simultaneously change many SQL sentence, more over in the procedure connects the button-up operations also increased the extra risk which the database server collapses;Useing the EJB already has become thelong-enduring data the recommendation way recently, but CMP correspondencetable granularity excessively thick, could not completely use the rich Java data type, was insufficient to many condition connections and theinquiry support, moreover, EJB only could put in the EJB vessel uses,very difficultly entrusted with heavy responsibility its code outsidethe vessel; The Hibernate frame is completely object-oriented relational model, in the performance history has removed very many tedious work, enables the development to be allowed to concentrate the businessproblem in the realization, no matter the development use starts fromthe territory model from the top application development strategy, or starts from the existing database pattern to use Hibernate and the suitable tool from the bottom upward development, all will be able toreduce the massive development time, will complete to the lasting level development also more and more many uses Hibernate frame.This article studies the theory and the practical application will unify, effectively will solve the practical application. This system design has solved two actual problems well, the concurrentquestion and the multi- pharmacies send the medicine question.Basically has met user's needs, has achieved the anticipated goal.
