"Enterprise computing and open systems - what are the distinctions between the two. Open systems are oriented towards an environment where most or all of the computing technology that comprises that environment is based upon standards regardless of the scope of the environment - departmental or organization-wide. Enterprise computing, by contrast, encompasses not only open system concepts but, by virtue of existing environments that must be incorporated as well, a great deal of proprietary interfaces and interoperability mechanisms. In the early 1990s, as both movements were beginning to gain momentum, there was some degree of overlap between open systems and enterprise computing, the amount of which was hindered somewhat by the stage at which enterprise architectures and standards were. It was anticipated that over time, as the enterprise architectures, open standards, and products built on one or both evolved and matured, the gap between the two would narrow and a greater degree of overlap would occur. As it turns out, the two movements have converged..."
