Research Of Small And Medium-sized Medical Information Service Platform Based On Sca Multi-tenants

With the development of Internet technology, the medical institutions in order tofacilitate treatment in the health care system and health knowledge of universal accessto information making efforts to build perfect information service system. Currently,with the rapid development of new small and medium-sized medical institutions, thetype of the corresponding medical information service platform is also a wide range.Construct similar information service platform repeatability resulted in a waste ofresources, making some small and medium-sized medical institutions subject to thetraditional software development model of high investment and high risk. For theseproblems, the current solution is not mature in the field of medium and small medicalinstitutions.Under this background, Firstly, the paper analyzed existing information servicesystem of small and medium-sized medical institutions, combined with SOAarchitecture, building a service model--DSCA (dynamic service components model)based on SCA model. On this service model, according to the user’s business needsbroken down into specific service component, to component-based approach totreatment after which the assembly according to certain business rules integration,publish to DSCA service registry, the service registry based on the user’s needs,dynamically adjust the actual needs of the service status to meet ever-changingbusiness needs.Secondly, Analysis the existing medical information systems found that thetraditional system only for a particular medical institutions, in full consideration of thecharacteristics of medium and small medical institutions, the study proposes to meetthe small and medium sized medical institutions, multi-tenant data extension datamodel to build a configurable, easy to expand medical information service platform,both to meet the common needs of small and medium sized medical institutions, butalso to meet their customization.Finally, the actual project as an example to verify the proposed of SCA-basedservice model and multi-tenant data expansion model medical information serviceplatform for small and medium sized practical applications.
