thread_title: Verbless sentence

message: This page seems to need a lot of work.  I cleaned up some stuff in the introduction.  Even this talk page is not structured in the standard Wikipedia format (use the + tab to add a new section in this talk page, please).
One thing that I have a question over is whether titles of specific IBM products ought to be linked to the appropriate Wikipedia article/section.

thread_title:  Whoa 

message: The article seems something like an advertisement with the language toned down a little bit.  Although readers of the article may want to know details such as the pricing of various systems, it should still exhibit a fairly normal encyclopedia style.  I don't think there should be external links to products in the body of the article, such as DB2 9 Express-C and SUPRA SQL[1] (under []; external links should go at the end.  Someone more familiar with Wikipedia styling correct me if I'm wrong.  I worked on some of the problems (maybe I'll get back to it later).

thread_title:  Ad language? 

message: The article says that
"contrary to popular belief, does not stand for Structured Query Language"
I have never seen any other source to say that SQL does NOT stand for that, in fact, everything I've ever seen says it stands for that.
So I do think that it stands for that, even though it may not exactly be the correct definition.
Look at the Wikipedia article about SQL: At the very beginning it says that SQL stands for Structured Query Language. Thus this statement in this article compromise the integrity of Wikipedia as a whole, doesn't it?  —Preceding unsigned comment added by Albertvanbiljon (talk • contribs) 10:51, 16 July 2008 (UTC)

thread_title:  Template for organizing IBM DB2 articles 

message: I am a DB2 for LUW consultant with about 10 years' experience.  I also bought a copy of DB2 Common Server v2 many years ago.  My understanding (from Don Chamberlin's book "A Guide to DB2 Common Server: using the new DB2") is that DB2 Parallel Edition (the shared nothing partitioned database available on UNIX only) was merged with DB2 Common Server v2 (the first edition to use Starburst technologies, and the first to have a common code base across different platforms - UNIX, Windows and OS/2).  The merged product was branded DB2 Universal Database v5 (skipping several version numbers). Later on, OS/2 support was dropped and Linux support added, and the product eventually rebranded DB2 for LUW.  Note also at some point a few years ago IBM marketeers in their wisdom rebranded most of the other flavours of DB2 (e.g. z-Series, i-Series) as DB2 Universal Database, even though the code bases remained very different.  —Preceding unsigned comment added by 122.59.32.64 (talk) 03:27, 22 February 2011 (UTC)

thread_title:  Reads like a marketing brochure. 

message: The article under history says: "When IBM released its first relational database product, they wanted to have a commercial-quality sublanguage as well, so it overhauled SEQUEL and renamed the basically new language (System Query Language) SQL to differentiate it from SEQUEL."
Really? I think we need a reference for "System Query Language"  Additionally, the SQL page says that the name was changed due to a trademark and it's cited; so I replicated a sentence and citation from that page here.  If we can't come up with a reference for System Query Language, I think we should remove it.--Doug.(talk • contribs) 05:45, 18 February 2013 (UTC)
replies: text: At a System R reunion in 1995, Don Chamberlin claimed that as a result of a trademark dispute " ...  I think I was the one who condensed all the vowels out of SEQUEL to turn it into SQL, .... " Since Don Chamberlin is one of the authors of the paper describing SEQUEL originally, one can conclude that SQL is an acronym for SEQUEL, which could not be used as a brand name because lawyers claimed that SEQUEL was already trademarked to the  Hawker Siddeley Aircraft Company in Great Britain. This implies that SQL is effectively still an abbreviation of the phrase  Structured English Query Language and the reason it needed to be differentiated from SEQUEL was to avoid a trademark dispute and had nothing to do with an overhaul of SEQUEL. The suggestion that SQL is short for System Query Language or even Structured Query Language is perhaps reverse engineering the meaning of SQL at a later date without reference to the recollections of people who came up with the name originally. - Cameron Dewe (talk) 02:11, 3 June 2017 (UTC)

thread_title:  DB2 vs. DB/2 

message: I have heard this claim many times that DB/2 was the first relational database, or at least IBM's first.
I'm sorry but this is simply not true.  According to this page, DB/2  came out in 1981.  However, take a look at the System/38 page.  It was announced in 1978 and delivered in 1980.  The S/38 operating system, CPF, included an integrated relational database system. http://www-03.ibm.com/ibm/history/history/year_1978.html.  As IBM's own 1978 history page says, "The System/38 is the only commercial computer with a built-in relational database".  Interestingly I could find no mention in IBM's timeline of DB/2 (same reference).  When DB/2 did come out, I assumed at the time that this was the reason for the "2", but I have since read that was not the case.  
The S/38 database was carried forward into the AS/400.  When DB/2 incorporated int OS/400, it was interoperable with the original "native" database system.  We probably should mention something about this feature under DB2 for i.  The system allow applications to use database tables and views interchangeably, regardless of whether they are SQL created objects, or "native" DDS created objects.

message: I've tried to take a shot at cleaning up the page to remove the marketing. There is still a lot there, and it's difficult to untangle. Much of the History section feels like marketing fluff, but I tried to not just delete the whole thing, and instead targetly cut out the marketing words.

message: Any thoughts on that? IBM DB2 Express-C does not seem to do very well on stand-alone notability, so I think it could be combined with this parent article. --Piotr Konieczny aka Prokonsul Piotrus| reply here 07:46, 14 November 2016 (UTC)
thread_title:  Merge from [[IBM DB2 Express-C]] 

message: Article says:
:Historically and unlike other database vendors, IBM produced a platform-specific DB2 product for each of its major operating systems. However, in the 1990s IBM changed track and produced a DB2 "common server" product, designed with a common code base to run on different platforms
Is that really true? Aren't large parts of the DB2 z/OS code still written in PL/X? I'd believe that IBM tries to share some feature code between platforms where possible, but that doesn't change the fact that the different DB2 variants are radically different code bases, even written in completely different languages. DB2 for z/OS (and I presume also DB/2 for VM/VSE) contains substantial bodies of code in PL/X, whereas LUW is a PL/X free zone. I'm not sure what DB2 for IBM i is written in – but putting aside the question of implementation language, the radical integration which exists between DB2 and the underlying OS on IBM i almost certainly implies some quite different code and architecture compared to LUW in which that radical integration is absent. (I'm sure IBM marketing wants to downplay the divergence in code between the different DB2 variants, and play up the common code, but I strongly suspect the divergence still outweighs the commonality.) 119.17.50.2 (talk) 09:54, 16 December 2016 (UTC)
