Identical weather stations were planted at both Fisk University and North Carolina A&T State University (NCAT). The stations are capable of transmitting data every minute to a receiver, which in turn would store the data at five minute intervals to a database at each university. A server and a simple client interface were then constructed for both databases, allowing anyone to access the data contained within. These servers were built as SOAP servers, including a WSDL file that contained the structure necessary for data communication between client and server. The ultimate goal of the project was to integrate both of these servers using a workflow. Though typically used for business applications, workflows provide an extremely simple and straightforward method for directing data from the databases at Fisk and NCAT to the client. This data could also easily be processed and manipulated upon request. Though both servers operate well independently, at the current state, the workflow software being used, Kepler, does not provide a 100% success rate at connecting and retrieving data. The code is still being modified so as to be compatible with Kepler, and the project is still a work in progress.
