IT-Facts: statistics and studies
One of JoinVision's projects is to publish informative statistics, particularly for its users, but also for the public, beginning with the so called "IT-Facts". These periodic studies are based on the data, which are fed to the portal by the IT-experts and freelancers on the one hand, and by the bidders of jobs and projects on the other hand.

June 2006: Open Source on the fast lane
|
The first issue of the "IT-Facts" thematizes current trends in the area of operating systems, programming languages, and database systems since 1990. From the information gathered from the CVs of IT-experts, a trend towards Open Source software is visible.
This can be particularly observed in the field of databases, where the Open Source product MySQL is used by nearly 30% of the JoinVision Community. This means, that this Open Source product is used more often than such renowned databases as Oracle or MS Access/SQL-Server, which have a contingent of nearly 25%.
In the area of operating systems Linux, currently at 27%, is gaining in importance at the expense of Unix or Unix-derivatives (currently only 10%) and of mainframe systems. And Microsoft can scarcely maintain its nearly 60% of Windows.
This shift to Open Source is also noticeable in the area of programming languages. In the 90s PL/I, Cobol and Assembler dominated the Mainframe development, C and C++ dominated the Midrange development with the overall share of 70%. Now Java, Javascript and PHP are constantly gaining in importance and are currently at the rate of 50%.
