Talk:Object database

message: 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!

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!

message: 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.

message: 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.--Bmccaff 15:20, 15 July 2007 (UTC)

message: "a relational database becomes cumbersome to use with complex data." -- This sentence does not seem to meet NPOV criteria at all.

thread_title:  Claims re: relational database versus object database 

message: Further to my above comment, I think this whole article has serious NPOV issues!  It reads more like an advocacy article ... for example : "Although some commentators have written off object database technology as a failure, the essential arguments in its favour remain valid"  -- this is opinion unless someone can provide references, or at least say "some consider that ...".  Ryandaum 01:03, 9 February 2006 (UTC)
replies: text: I am marking this with an NPOV tag, for the above reason.  The article reads like an advertisement.  More examples: "thereby making OODBMS ideal for OO programmers"; "companies have a vested interest in OODBMS to display their complex data"; "Using a DBMS that has been specifically designed to store data as objects gives an advantage to those companies that are geared towards"; "Access to data can be faster because joins are often not needed"; "The efficiency of such a database is also greatly improved in areas which demand massive amounts of data about one item. For example, a banking institution could get the user's account information and provide them efficiently with extensive information such as transactions, account information entries etc. The Big O Notation for such a database paradigm drops from O(n) to O(1), greatly increasing efficiency in these specific cases.".  -- DBooth (talk) 19:49, 24 September 2010 (UTC)
replies: text:  I've removed the uncited paragraphs. I am doubtful about the remaining paragraph as well - the prose seems to attempt to compare relational datbases with object databases, but the wording is such that it just mentions benefits of using an object database - and it might be that the cited references (which are unfortunately all offline) don't actually compare to RDBMs. If the paragraph compares object databases with e.g. coding your own data structures, or storing things in flat files, it makes little sense to have it there. Perhaps someone with access to the references will clear up the wording. W (talk) 22:03, 20 March 2011 (UTC)
replies: text:  I removed the claim of high performance after checking the cited article, and replaced it with a soundbite of the article's actual claims.  Concur that the remainder of the paragraph still has issues. --Ott2 (talk) 17:18, 29 March 2011 (UTC)

message: Is a Smalltalk programming language image (such as in VisualWorks) an Object Database? Wouter Lievens 10:54, 23 March 2006 (UTC)
replies: text: 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. MadScientistX11 (talk) 01:56, 16 December 2013 (UTC)

text: 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. Cameron Purdy (talk) 14:43, 9 September 2019 (UTC)

message: I come from an undergraduate computer science background and have some experience with object-oriented programming languages like C++ and Java as well as exposure to the object-oriented design model of software engineering and knowledge of the theories behind relational databases, but after reading this article, I still don't have a clue what an object-oriented database is.
The way the article currently describes it, an object database seems no different from any object-oriented framework like the Microsoft Foundation Classes (MFC). It mentioned traversing objects using pointers. Does this mean it's another name for a binary search tree and similar abstract data types?
I just did a Google search and found The Object-Oriented Database System Manifesto. Maybe citing information from this will clarify the subject for people who are trying to learn about something they don't know.--NeantHumain 02:28, 28 July 2006 (UTC)
replies: text: I think the difference is that an Object Database offers persistance and query, while a class models offers functionality.  An instantiated MFC application when running is an instance of an object database, but a very small one. and it's query is limited to very specific things (query by windows handle). - Drdamour (talk) 20:43, 18 June 2008 (UTC)

replies: text: If the OODB is intended for serious professional software development, it will not be tied to one specific OO language.

message: "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.
