Thread: Openbase makes false claims about postgresql
I don't know if this matters to anyone, or if this is even the right list for this, but while doing some research on acid compliance, I found this: http://store.openbase.com/ChoosingTheRightDB.pdf ...which is dated 2004, is currently available, and states on page 2: "PostgreSQL also offers fairly good A.C.I.D. compliance, although their documentation warns that their write-ahead logs are not 100% reliable." Page 4: "PostgreSQL has recently added a write-ahead log to address their reliability problems. It operates on the same principle as a journal, except that the log is written before SQL is evaluated, rather than as the transaction commits. While this provides better reliability for PostgreSQL users, PostgreSQL documentation warns that there are still known problems with their write-ahead logging system, which could cause data loss. The answer? Many people offering PostgreSQL also sell database consulting services." Then on page 6: "PostgreSQL also provides reasonable transaction support, although, as noted, they do warn of problems with the reliability of their write-ahead journal." V7.1 was released 2001. Four years later after being addressed, (a long time IMHO), they are making these claims. Page 11: "PostgreSQL does not have a database clustering option." ...built in. I realize that this is some company's marketing drivel, but I also thought someone might like to complain in an official capacity. PS: I am off-list, so please CC :-) -- karim.nassar@acm.org
I am not generally happy with what they say in their benchmarks section either. But we all know how rigged benchmarks generally are. According to their documentation site, they haven't released a product in almost 2 years (before they were releasing every couple of months). Not sure yet, but it seems that development has ceased? This doesn't look like a good sign. So is it really worth hassling them over this?

There development may be dead, but they are still shipping product, updating their website news, and have a developer conference scheduled to take place in the next month. I don't think it would hurt to ask them to clarify things a bit.

Folks, See, it pays to ask nicely: ------------------------------- Hi Josh, Thanks for the heads up on that. We'll edit the white paper and get that corrected. From what I have heard, PostgreSQL has become one of the fastest growing in the Open Source market. Congratulations! - Scott OpenBase ------------------------------- -- Josh Berkus Aglio Database Solutions San Francisco

But according to their downloads section, they made an update June/July (depending on platform). Also, they are having a developers conference in September. I would say that they are active. -- Karim.Nassar@acm.org
