CSB.DB is strongly interested in working closely together with the scientific community. As a first part of this aim we develop an open source database which can be freely accessed by non-commercial users. Moreover we are interested in user feedback to improve data structure and retrieval according to the demand of the scientific community. CSB.DB Associated Web Pages and Databases provides the infrastructure for data storage and exchange, which is particularly useful for international research projects with many partners. Data can be uploaded, the access can be restricted by a login, or the data can be made publicly available.
