The use of database for different kind of data is nowadays common. Especially in sectors, which work with a huge amount of data, databases are used. Such an example is a gait analysis laboratory. During one year a huge amount of data will be collected. Based on the amount and high quality of the data, they suits perfectly for a meaningful study. To enable such a scientific analysis, based on different scientific issues, the information has to be brought together and stored at one single place. This central storage of the data makes scientific studies time-saving and costs-saving. Based on the during this thesis developed concept of a scientific database and WIDAGA it is possible to draw samples from gait analysis data for different scientific analysis easily. The amount of data for scientific use can be extended easily be cooperation of different gait analysis laboratories. But in this case the data protection act has to be minded. Especially the rules for data sharing and data exchange have to be noted. Based on functionality of WIDAGA the economic efficiency of scientific studies in the gait analysis sector can be increased.
