Object-relational impedance mismatch is by far my favorite research topic, mostly due to the fact that it has a very practical implementation. I would make even stronger statement: the most rewarding optimization is the one when you can reduce the number of SQL statements executed when a web page is rendered and all of a sudden it is loaded 50 times faster (and I mean actually 50 times, not figuratively speaking!). It always looks like a magic – and I haven’d done anything!
This been said, the ORMs are my worst enemies, and I am always looking for opportunities to promote the better ways of communication between a database and an applications. Most of the time the human factor appears to be more important than the technological challenges, so I always think about these projects as battles.
At Braviant however, first time in my professional career I had nobody to fight about this issue – the app developers were completely on board with my approach since day one. Which allowed us to develop something really cool, and to optimize the interaction between databases and application to the point of absolute perfection. SO, when my husband suggested we’d write a short paper about this project, I had no doubt it will be accepted – because two of my previous papers on the same subject were accepted to the very serious conferences.
Life proved me wrong :), I am not going to name the conference and the workshop, but I have to make some comments about the reviews, so that the level of my frustration can be understood.
One of the reviewers asked: why we think that the number of round trips defines the response time of the web application. Another reviewer asked, whether we tried to use Mongo DB :))). And why we think that (de) serialization of the JSON takes negligible time. And why we think Hibernate is worse.
I think the only valid objection was, that the topic of the paper is not relevant to the workshop topic. And the latter might explain the whole story.
Several years ago, when I started to attend the database conferences again, after fifteen years of absence, I made an observation that a significant number of the attendees never saw the real applications, and never had deal with performance problems, Fortunately, I’ve also met and got to know some really outstanding researches, whom I admire and feel honored to be aquatinted with, so… I am sure I will find the right place to showcase our work.
And may be it’s time to get back to my old “HDAT” workshop idea,,,
And for my fellow Chicagoans: I will be presenting this work this Tuesday, Feb 13 at the Chicago PUG meetup!
