Realistically, it is too late for WO to penetrate that space. The combination Oracle controlling Java, the current love affair with weak typed scripting platforms like node.js and academia's love of doing things the purist way instead of pragmatic means that academic trained programmers will forever more be I'll prepared for the real world.

Greetings James,
I tend to agree, but there are somethings that MySQL had going for them. Most notably, they were able to get academia to tell just about every student to build a web page with PHP and MySQL. They even had them recommending the two of those in book after book. Something that would help us is the notion of the concepts of WO (all of the design patterns manifested by WO). At that point, the academics think that it is their idea and they spread it. Hopefully with a good database engine.
Just a thought,
Dan

The first one to appear was mSQL* (aka miniSQL), which wasn't technically open source, but it was free for non commercial use, and distributed as source. It was initially an sql query engine that ran on top of Postgres (back then Postgres wasn't an SQL DB), but later implemented its own backend storage.
>>
>> About a year, maybe a year and a half after mSQL's first release, MySQL appears, and it just happened to support all the same cli syntax, similar admin tools, etc as mSQL, it was basically a straight clone of mSQL but GPL and free. The origin of certain chunks of the source that were in the initial MySQL releases were also suspiciously similar to those found in mSQL.
>>
>> Initially neither product supported concurrent queries, however MySQL quickly introduced support for them using threads, which basically sucked for years, but is was a differentiator that took many years to be matched by mSQL (release early vs release when it actually works). At this time, mSQL was very stable, and MySQL basically sucked unless you used exactly the right config and feature set, but had the potential to do well once all the feature bugs were worked out (which took another 4 years or so).
>>
>> For a while the two products were pretty comparable in features (that worked), performance and popularity, but the non commercial use license and a growing MySQL feature set eventually spelled the demise of mSQL's popularity. MySQL went on to dominate the free sql database product space because it was basically the only choice that didn't cost money to use commercially, and support concurrent queries. The appearance of php in 1995 helped widen that gap as demand for small SQL databases grew, despite it supporting both products equally.
>> At that time mSQL already had a similar web programming language distributed with it called Lite, but that's a whole other story.
>>
>> MySQL grew from humble and possibly slightly illegitimate beginnings for the purposes of being something very simple, very small, and very fast. Things like ACID compliance and MVCC were liabilities to speed and simplicity and not part of the original plan. It was never intended to be even remotely comparable to the Ingres, Sybase, Oracle, DB2 or Interbase servers of that era.

The net result is that in order to get the performance I needed, I was going to have to alter things to be MySQL specific, rather than the standard syntax that works across multiple backends. Hardware was not the limit. The data in question was in how MySQL coped with a 5th normal structure and pulling in detail information associated with a master entry record. The problems stemmed from the join and a table scan caused my MySQL's inability properly user the index. The same request against the same data in every other platform of note executed better than 2x as fast as the MySQL implementation, in some cases on the same hardware, but most on inferior hardware.

>>> I understand your point, and yes, there are/were solutions. My point being, that MySQL has limitations. They can be overcome, but the further you push it, the more difficult and expensive they become. Unfortunately, I've been down this path a few times with several platforms. MySQL, OpenBase, MSSQL, Oracle, Informix, Sybase, DB/2, and PostgreSQL to name a few (I have only used FrontBase for prototyping so I have no deployment experience with it and do not include it for that reason). Everyone one of them has trade-offs and limits. Based upon that experience, for any project I start today, PosgreSQL would be my first choice, with Oracle and MSSQL being 2nd and 3rd. MySQL would be absolutely dead last. *if* it was a project that had Twitter size scaling issues, I would consider altering that to use DB/2 as the platform of choice, because of it's ability to cleanly scale to IBM's z series hardware, but even then I would have to weigh the benefits versus the limitations of DB/2.

>>> In case it hasn't been obvious from the beginning. I loathe MySQL, both technically ( it is still basically a SQL engine grafted to a text based data engine ala PICK, DB4, Progress or Paradox ) and philosophically ( GPL applied to the data access libraries rather than LGPL ). I do not argue that both can be worked around, but bluntly spoken, if it is a serious RDBMS and it wants to play with the big boys, then I should not have to.

Possibly your engine selection, /etc/my.cnf and/or hardware/memory allocations might not have been appropriate in the setup that failed to meet your expectations. I found this book helped a few years back when I got started with MySQL http://amzn.com/0596101716 - and, as I have said before, the default out of the box settings in MySQL are dismally constrained and probably designed for someone doing basic development on a small memory PC.

If I was starting right now and had to spend the time becoming familiar with the detailed ins/outs/ and configuration of a new database platform, I would probably try PostgreSQL since it has deferred constraints and it is open source.

Skipping over the license issues, and going straight to the real stuff, MySQL has been shown repeatedly to have very real and finite limits on growth and scalability. Google, twitter, facebook, etc have all built foundations on MySQL only to hit walls, and implement obscenely expensive workarounds.

Marketing a proprietary SQL database these days is swimming upstream, you can't expect wide success. FrontBase fills a niche market, of which WO is probably less and less every year. As long as their goal is to target their niche (and they do so well), they will keep going. Neither FrontBase or OpenBase are ever going to replace MySQL.
