ABSTRACT The deployment environment requirements of e-healthcare operation in Nigeria were puts into perspective in the interoperability middleware design in order for the middleware to work successfully where it is deployed. This includes the requirements shaped by the infrastructure available at the deployment area which are; network, electric power supply, finances, device availability etc. It further explores issues such as users and structural readiness to adopt new technologies made available to them for use and the culture of the deployment environment. The interoperability middleware design presents the resource case that highlights the resource constraints that have to be put into consideration during the middleware s development. The resource case enables operational decisions that will make the system function with the available resources when deployed. Existing middleware technologies were selected and comparative evaluation was done on them using quality requirements. The design of the middleware operation was done using: Simple Object Access Protocol (SOAP), Web Service Definition Language (WSDL) and Universal Description, Discovery and Integration (UDDI). The interoperability operation was designed using: Extensible Markup Language (XML), Entity, XML Schema Library, Service Provider, Service Requestor and Service Registry. The designed middleware took into consideration two functional applications of the middleware for interoperability, though multiple applications can exist on the middleware. These applications are: i. Electronic Health Record (EHR) and ii. Medical Billing System (MBS). Mobile Broadband in form of GPRS, 3G communication is recommended as the internet connectivity option for implementation. This is due to its minimal cost and effort to set up. This is minimal due to the existing massive investment in telecom infrastructure by telecommunication companies in Nigeria. Keywords:- Middleware, Interoperability, Service Provider, Service Requestor, Service Registry, Requirements
