For more than three and a half decades, MITEM has dedicated itself to the research and development of technology crucial for refining an integration framework aimed at composite application development, known as MitemView. This framework enables seamless integration with legacy systems, middleware technologies, application servers, web services, and various vendor-specific interfaces. MitemView consists of a versatile developer toolkit alongside a runtime engine that allows users to merge new applications with existing legacy systems effortlessly. In addition to this framework, MITEM provides business applications that capitalize on MitemView’s robust integration capabilities, flexibility, and reliability. These applications represent a natural evolution of our foundational technology, drawing from over 35 years of expertise in crafting end-user applications. By utilizing a composite application, one can effectively reuse the functionalities of established legacy systems to innovate new applications, thereby blending the capabilities of multiple legacy systems with those of the new application for enhanced performance and productivity. Ultimately, this approach fosters greater efficiency and adaptability within organizations as they navigate the complexities of modern technology landscapes.
