==Merge==
Following all the indecisive debate about merging, I took the plunge and wrote a pretty-well new article on object databases, changing the OODBMS article to redirect to it. (Although the two terms have different meanings, this wasn't reflected in the articles, which were both writing about the same thing). Neither article was very good, both were rather opinionated, and I hope the overhaul is a better basis for moving forward. It's not anywhere near perfect yet and I hope others will improve it, but I felt something had to be done!

==OMG==
Should correct the page regarding OMG -- they were granted the right to develop new specifications based on ODMG 3.0; they did not "acquire" it.
Made the mods discussed <s>below</s>''above'' and added some text to explain better what the Object DB Technology WG is intending to do (am a member of it). Thought about adding a link to the Request for Info that was the basis of the 'announcement' cited in the article but decided not to. However, let me use this as a forum to encourage response from those who are interested in this technology area. Responses are due 1 June 2006. Here's the link: http://www.omg.org/cgi-bin/doc?mars/2006-2-18.

==Doug==
Thanks for your updates, Doug: nice to have solid information from the horse's mouth, so to speak. I would criticize your contribution as being just a little bit lacking in dispassionate analysis, but that's the price you pay for getting a contribution from someone who was intimately involved!

==Links==
Cleaned up the links -- removed three, one of which was dead, left the one to the open source benchmarking site and to the ODBMS.ORG site, which is sponsored by OMG through their European agent, Prof Robert Zicari but is hosted (physically) by an open source ODBMS vendor, db4o. "Unspammed" the two remaining. My WikiEditing may stink so hope others can clean it up (if need be) and make it right.

==For History==
The list of the notable object-oriented management systems is a little excessive right at the top of the article like that. The reader starts to lose interest before he or she gets into the meat of the article. I'd recommend striking most of that and then including a list of the notable systems in an infobox to the side, linked from the history section.--[[User:Bmccaff|Bmccaff]] 15:20, 15 July 2007 (UTC)
The first two entries (MUMPS and Intersystems) were not (and seemingly are not, unless something changed in the last 24 months) object databases. They are both hierarchical databases, but can both be thought of as document databases (or blob stores). While an object can be converted to a hierarchical structure, document, or a blob, that does not make MUMPS or Intersystems databases into OODBMSs -- any more than hanging a tire swing turns a tree into a car.

==For Technical Features==
In Technical Features, it's written that joins aren't necessary because objects can be located directly by pointers. Are these pointers indexed? How are the pointers referenced by a query? --[[User:Bmccaff|Bmccaff]] 15:24, 15 July 2007 (UTC)

Is a [[Smalltalk]] programming language image (such as in [[VisualWorks]]) an Object Database? [[User:Wlievens|Wouter Lievens]] 10:54, 23 March 2006 (UTC)
:I don't know about VisualWorks but I'll answer the general question. No, a Smalltalk environment or image is not an OODB. The Smalltalk objects only persist while the image is live. For an OODB you need to have real persistence, not just when the program is running but stored to a persistent storage mechanism that persists past the life of any one program and can be accessed simultaneously by multiple systems. It's possible that some Smalltalk products (e.g. Visualworks) may provide additional DB capabilities but just a vanilla Smalltalk environment is not a DB. [[User:MadScientistX11|MadScientistX11]] ([[User talk:MadScientistX11|talk]]) 01:56, 16 December 2013 (UTC)
:In a sense, the Smalltalk programming language "image" is an object database, but not in the sense of a database management system. It is far simpler to think of it as a recoverable core dump. Gemstone/S, on the other hand, is an OODBMS built on top of Smalltalk, and it seems to meet all of the requirements of being an OODBMS.

== Objective-C ==
I've added [[Objective-C]] to the list of OO languages since there is an object database for this programming languages ('''EntropyDB''').

:If the OODB is intended for serious professional software development, it will not be tied to one specific OO language. That is one of the points of using an OODB so that you can get persistence that isn't tied to one implementation.

==High performance==
"Object databases are generally recommended when there is a business need for high performance processing on complex data."
I can't let that one pass - whatever the advantages of object orientation, "high performance" isn't one of them. Flexible, probably. It may help with the design process. But the corollary of this is the performance hit you have to take.
--[[User:Fjleonhardt|Fjleonhardt]] ([[User talk:Fjleonhardt|talk]]) 13:50, 16 May 2008 (UTC)
Fjleonhardt: That's misleading: "high performance for complex data" is not the same as 'high performance". And object orientation is here compared with a relational database model, not with structured programming. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/80.101.206.228|80.101.206.228]] ([[User talk:80.101.206.228|talk]]) 09:30, 17 January 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
While as mentioned below "high performance" is not an advantage of object orientation, I think performance should still be discussed in the article. Whoever is implementing an object oriented database (for all its benefits), still desires as high a performance as possible. I recommend bringing in the OO7 project into the article. OO7 is the seminal work in OODBMS performance. This is the link I found for the paper I read a while ago.
