The fast-paced advancement of information technology is rapidly changing the business world. Fulfilling on-demand service requests is vital to today's business survival. Enterprises must incessantly upgrade and integrate their e-infrastructures in order to maintain their competitive advantage. One major roadblock to integration is that there is usually an inherent heterogeneity of system platforms and software applications existing within the same enterprise and among collaborative partners. Thus, it is common that enterprises must spend an astronomical amount of time and money to link the new and legacy systems in order to exchange data, information and knowledge. The recent development of Web Services has greatly improved information-sharing and -exchange. Simply stated. Web Services use XML-related technologies such as SOAP as the communication protocol; WSDL as the interface description language; and UDDI for registering and searching services. In this paper, we establish an integration framework to develop web-services-enabled enterprise applications utilizing the UML tools. To achieve the desired integration, a uniformly integrated user interface will be designed and developed. Under the proposed framework, heterogeneous systems and applications across different networks can exchange and share data with a minimal need to add or change the existing hardware or software. Lastly, a completed case study [12] of the presented integration framework is briefly illustrated.
