QsarDB has its roots in 2005, has been developed since 2007, and has been on Interent since 2008 and at the same time in active in-house use. The year 2012 was an important milestone in the development of QsarDB. For the first time, we presented the design of QSAR data formats at conferences. The transition to the new data repository platform and the new look of the data repository also remained in 2012. Then we also started collecting different visible milestones and sharing them with the general public.
