In safety-critical systems, Ada is a major player. In desktop applications, Ada is a negligent player. In real-time embedded systems, Ada is probably the number 3 or 4, above languages like Modula, Eiffel, Pascal, but below C/C++. It is not clear where Java is in this market yet. > - Where is the Ada Tools market - total size, increasing or decreasing? Slowly but steadily increasing, somewhere in the range of $100-$200 million (it is hard to be more specific because most of the companies are privately held, or don't break out their Ada tools business separately). > - How much is Ada 83 still being used vs Ada 95? There are a number of large legacy projects that cannot justify upgrading to Ada 95, except as part of a major system upgrade. The large majority of new Ada projects use Ada 95 compilers. It is of course hard to know which Ada 95 features they use. One can certainly continue to program in mostly-Ada-83 using an Ada 95 compiler, which makes sense in some environments. > > Many thanks, > > Chris Chedgey. > Headway Software Ltd. > email: chrisc at headway-software dot com -- -Tucker Taft stt@averstar.com http://www.averstar.com/~stt/ Technical Director, Distributed IT Solutions (www.averstar.com/tools) AverStar (formerly Intermetrics, Inc.)
