Notes:
The Easy CHCS Provider Portal solution consists of the following physical components:
CHCS Clinical Data that contains the MUMPS data for all functional areas of CHCS.
The CHCS Server. Running within the CHCS environment is the EsiObjects runtime environment. Within EsiObjects resides all the object wrappers for the various functional areas of CHCS (Patient Wrappers, Laboratory Wrappers, etc.). In front of that is the Application Façade that is the application interface to the database wrappers. Its purpose is to simplify the interface to the application.
The Application Server. The Easy CHCS application is implemented using Java Server Pages. These pages are served up to the Presentation Tier.
The Easy CHCS Provider Portal. The portal is a GUI presented via a Web browser that runs on PC’s or more economical Web terminals. The environment is based on the point and click metaphor and is more intuitive than the traditional dumb terminal roll and scroll.
The following are logical components of the Easy CHCS Provider Portal:
Database Tier. This layer consists of the CHCS Clinical Data and the functional object Wrappers. This tier reproduces the exact functionality as the CHCS File Manager layer in the legacy system.
Application Tier. This layer consists of the Easy CHCS Application running on the Application Server interacting with the Application Façade running on the CHCS Server.
Presentation Tier. This tier consists of the Easy CHCS Provider Portal.
