FMW Web is developed using the Java system, on both the Client and Server tiers. Java (a technology from Sun Microsystems) is an industry-standard, mature and highly functional system development platform, suitable for both client and server development in a web-based environment. It has the added advantage of being a cross-platform technology, and so software developed with Java can operate on all major operating system platforms, such as Microsoft Windows, Apple OS/X, Linux and Unix. While the vast majority of environments in which FMW Web operates run Windows on the Client and Server tiers (the Data tier is more likely to run a DBMS on an operating system other than Windows), Linux and Apple OS/X are becoming important platforms in some environments.
