Keystone uses its deep technical resource and experience to integrate “best of breed” products and technologies as the basis for the systems we implement for our clients, so that our clients do not need to have expertise in a wide array of technologies and products. Our application software operates with equal capability on the client’s choice of centralized server operating systems: Unix, Microsoft Windows or Linux. Keystone has representative implementations using all of these operating systems and with hardware manufactured by IBM, Hewlett Packard, and Compaq. Usually the decision of which to implement is based upon the client’s current environment and staffing capability.
The basis for Keystone’s application software is IBM’s powerful “U2” series database engine, UniVerse. We employ a 4GL development tool, OnGroup’s Blacksmith, to aid in rapid and consistent product development.
The application’s user interface marries the best uses of both a fully integrated Windows desktop client in some applications and functions, and a web browser based interface in others, (developed using ASP, ASP.net, and Java.)
Using industry standards such as ODBC and SQL, Keystone’s database and applications integrate well with a variety of standard office automation, as well as industry-specific application products.
