Abstract: For more than 15 years, the archive at STScI has revolved around DADS (Data Archive and Distribution System). Originally a software product delivered by a third party vendor to STScI, this system has evolved to keep up with new technologies and users needs. This evolution has encompassed changes in the core language from FORTRAN to Java, changes of OSes including moving from VMS to *nix, several transitions of the archive storage media, and the inclusion of on the fly processing for current instruments as well as reprocessing of heritage instruments. This evolution has also been driven by other missions archived by DADS (FUSE and Kepler) and expansion into the future with our JWST development. Currently we are transitioning from Sybase to SQLServer as our DB platform and Solaris to RHEL as our base OS. From this history and near future plans, we will present our list of both lessons learned and share common ideas needed to make more flexible and perhaps shareable archive components for the astronomical community.
