statistics - job / project offers - Development Families

IBM Mainframe (347), Java (5031), Microsoft (3030), SAP (5048)

Key:

The diagram shows the frequency of requested skills out of so called "skill families" from job and project ads in the last year. Skill families are a combination of technologically related skills. For example "Java" does not only include the programming language, but also technologies and products in the J2EE/SE area, such as Java-Applicationserver or specifications as EJB or JMS. Microsoft includes MS specific programming languages such as VisualBasic and C# as well as products such as Visual Studio (.net) or specifications like COM.

Remarks to the interpretation of the x-axis: At JoinVision skills are assessed related (slider) to the job/project offer. The x-axis of the diagram above matches the sum of the assessed skills. If a skill is required a 100%, it adds 1 unit to the bar; if a skill requires 50%, it adds 1/2 a unit to the bar. Therefore, the length of the bar in the diagram does not directly relate to the number of offers, but should be understood as a measurement for the cumulated importance/demand of a skill.
