Distributed Communication Methods and Role-Based Access Control for Use in HealthCare Applications

摘要

The use of software in the health care industry is becoming of increasingimportance. One of the major roadblocks to efficient health care is the fact that important information is distributed across many sites. These sites can be located across a significant area. The problem is to provide a uniform mechanism to integrate this information. This paper documents the results of an investigation into the suitability of several different distributed access mechanisms. Five methods were examined; the Common Object Request Broker (CORBA), Object Linking and Embedding (OLE), remote procedure call (RPC), remote database access (SQL/RDA) and Protocol Independent Interfaces (PII, the authors specifically examined sockets). These mechanisms were compared with regard for use in health care applications. In particular, the following capabilities were compared: Ease of use by the developer, Class of applications for which the technology is particularly effective in developing, Security capabilities.
