Sounds very i think this a fantastic argument, one more people should consider. if you want speed AND a RDBMS you need to rethink your rational - for example, how many people using mysql have schemas so simply that any key->value type database (BDB) would suffice? here in my group we store metadata in a postgresql database to ensure data integrity, to foster development, and to centralize metadata management. accessing _any_ RDBMS (note that mysql is _not_ a RDBMS) from our near-realtime system would be madness or expesive in oracle's case - we offload recent versions of crucial metadata sets into berstein's CDB (constant databases) for access by these processes, which are read only. even if we required write databases i would consider berkeley db, or any other database with the overhead of parsing sql. talking about speed and an RDBMS is like optimizing java code - just write it in c and be done with it! IMHO 'speed is not necessary' and impossible to acheive with _any_ RDBMS and so should not be considered. -a -- ==================================== | Ara Howard | NOAA Forecast Systems Laboratory | Information and Technology Services | Data Systems Group | R/FST 325 Broadway | Boulder, CO 80305-3328 | Email: ahoward@fsl.noaa.gov | Phone: 303-497-7238 | Fax: 303-497-7259 ====================================
