Key:
Comparison of the demand of skills (from job ads in the last year) and the supply of skills in the area of data base systems.
Remarks on the methodology of computing the statistics: Demand of skills is extracted from the job and project ads that have been released on JoinVision. Hereby the intensity of each skill is cumulated and normed to 100 % in the end. On the side of the supply of skills, the skills of IT-experts are cumulated. The emphasis is on current skills, meaning, that old skills are valued less. In the end the cumulated sums are repeatedly normed to 100 %.
