MySql is not "Commercial Grade". Although good in it's own right, it is lacking some dbm features. MySql is a "file based" B-Tree keyed file system with SQL layered on top. For "Industrial Strength" OSS, there are Postgres and Firebird. Another good "file based" dbm, is the BerkleyDBM. It has "transaction" journalization, something that MySql lacks. see: http://www.sleepycat.com Pick is the Old PICK Database/operating system. However, the database engine was latter rolled out as a stand alone product. The direct heir to PICK database is UniVerse/UniData, now owned by IBM when they acquired Informix. There is also the MvBase from JBASE. All these can be considered 4th Generation PICK DBM's, in that they support SQL, transaction journal's, external Index key files and several other features. MaVerick is suppose to be a OSS implementation of the PICK dbm, but in reality, it is a JAVA API that uses Postgres as the database engine while simulating MultiValues. As far as I can find, there is no "real" open-source PICK database engine anywhere. sixs wrote: > > > Hello, > I am wondering about Mysql. Isn't it one that is commercial grade.?
