摘要:

用powerbuilder开发工具的分布式对象实现三层结构式的医保数据传输。三层结构式的医保数据传输是在医保数据库服务器与公网之间加上1台数据传输应用服务,这台数据传输应用服务器上安装数据传输服务端程序,向公网开放数据传输服务端口,可以访问互联网外,其它的服务端口全部关闭;定点医疗机构的客户端通过互联网访问应用服务器上的数据传输服务端,医保数据库服务器设置为不能访问互联网,也不能被互联网访问。应用三层结构式可以安全地传输医保数据。

Abstract:

The three-layer structural medical security data transmission is developed by using the distributed class object of Powerbuilder.To adopt the three layers of structural medical security data transmission,we increase a data transmission application server between the medical security database server and public net.This data transmission application server installs client data transmission program,it just opens the service port for data transmission toward public net.Except for visiting the Internet outside,the other service ports are all closed.The client program of fixed-point medical treatment organization visits the client data transmission service on the application server through the Internet,the medical security database server is established for unavailable visit to the Internet,and can't be visited by the Internet,either.The three-layer structure can transmit medical security data safely.
