IT integration services—processes and technologies that combine different software applications and datasets to increase the effectiveness and responsiveness of any organization's operations. Central to it is the use of service-oriented architecture, or SOA, whereby services are self-contained but with well-defined interfaces described in WSDL files. These services facilitate the smooth flow of data and functionality across several systems, automate interactions, and make data flow easily without manual intervention. Such integration not only assists in the smooth flow of business processes but also supports complicated IT functions by reducing errors, increasing speed, and hence adding to the organization's ability to change in respect to business needs.
