In collaboration with the UCSF Cancer Center, we have developed a database to track data from all stages of the production and use of the CGH (Comparitive Genome Hybridization) expression array slides produced robotically by separate LBNL-Cancer Center collaboration. The system tracks clones or DNA and their sources as they are selected for use in the array, the DNA preparation, the microtiter plates, print-run specifications, slide-printing runs, and slides printed. Researchers then log experiments performed on slides, with the resulting slide-images and analyses written back to the database, providing results which link back to the original clone or DNA and its source.  

The system is implemented in an Oracle 8 database, served on the Web by a NetDynamics application server, providing a highly scaleable, flexible, and responsive solution. It is accessible from java-compatible web browsers, and can provide a fine-grained control of security and accessibility.
