Maintenance of documentation of chronic illnesses

The standard software is based on a three-layer architecture consisting of a WinForms client, an application server based on the http.sys core driver and an SQL 2005 database server. Web services based on WSE 3.0 are used to enable communication between the client and the application server. The application consists of a framework application and a series of modules that exist as assemblies (DLL) and are loaded to the application during runtime. A server and a client module are developed for the documentation of diabetes mellitus and coronary heart disease. These modules cover the full required functionality. An import and export interface is provided based on HL7-compliant XML documents in accordance with Clinical Document Architecture (CDA). Development is performed in C# based on the .NET 2.0 framework.
