Microarray data management and analysis system for NCI / Center for Cancer Research scientists / collaborators. Data is secured and backed up on a regular basis, and investigators can authorize levels of access privileges to their projects, allowing data privacy while still enabling data sharing with collaborators.

A scalable, modular, enterprise-level system for both microarray databasing and analysis over the Internet has been developed over the past four years by the National Cancer Institute's Center for Cancer Research in collaboration with NIH's Center for Information Technology. This completely Web-based system, called mAdb (for microArray database), is currently supporting over 810 registered users and collaborators at NIH and contains over 22,000 microarray experiments, making it one of the largest collections of microarray data in existence. In addition, the mAdb system has been ported for the Netherlands Cancer Institute, the Genome Institute of Singapore, and the CDC. This system has been used for a wide variety of scientific experiments spanning the range from cancer to studies of early development, and for human, mouse, rat, yeast, and numerous microbial organisms.
