ORM for Qt
-
[quote author="victorzhuk" date="1368309226"]maybe my orm desision will be healfull ;) https://github.com/victorzhuk/eorm[/quote]
- Is there any example or demo using it?
- Does the performance is quick as Qt's model or it's a slower a little bit (I'm not sure what if I used the loops instead of Qt's model the performance will be same as Qt)?
-
- examples are placed in documentation, use Doxygen to compose html docs. I can help if you don`t know how
- I think yes, but I don`t have chance to check this - I create this lib for personal use, and if you have any test results and ideas I can impove it :)
ps: sory for my english :)

Oops I don't want to build the project manually... I just ask you for tiny example :)

Do you mean it's slower? or it has same Qt performance?
-
if you need litle demo I can quick create it for you ;)
bq. Do you mean it’s slower? or it has same Qt performance?
library use only qt`s mechanisms, no boost or custom macros...and when I use it performance was the same
it`s will be great if my lib help anybody. wait for a sec, I post demo

For demo success working you should compile EOrm and add .so(.dll) and *.h files to EOrmDemo project (just replace paths in *.pro file)

Thanks, I successfully run the example :) it's quite easy to understand... I think eorm's performance should be as Qt's model.
Any way, I've to test it in heavy and excessive usage then compare it with the above libraries in addition to Qt standard model, this may take some time because I'm busy these days.
Do you want to share with me these tests?
I want to test:
- eorm
- QDjango
- Standard Qt model
-
sure :) how can I help you? what tests?
-
let
s try :) about examples - I find a time and upload some in git, with find,model,create,delete etc.. hope its help somebody -
Guys, I found this library which may works too. I'll add it for performance comparison.
https://sourceforge.net/projects/qtpersistence/?source=directory -
Until now I'm planning to test:
- eorm: https://github.com/victorzhuk/eorm
- QDjango: https://code.google.com/p/qdjango/
- QsT SQL Tools: https://sourceforge.net/projects/qstsqltools/?source=directory
- QtPersistence: https://sourceforge.net/projects/qtpersistence/?source=directory
- Standard Qt model
I'm still looking for others...

The Best performance was for QDjango, QxOrm and Standard Qt model. All three techniques gave same result in many cases but QxOrm is the best from features prespactive while QDjango is the best from simplicity and rapid usage.
Personally I use QDjango because it fits my needs while I left QxOrm becasue of license issue (actually it's heavy by comparing to QDjango)
-
I am leaning towards QDjango as well, but there are still a few questions left, one of which is about relationships. QxOrm supports them, but I guess I have to implement it myself with QDjango. Do you have experience maintaing relationships with QDjango?
Also, I noticed that QDjango uses API deprecated in Qt5 (I had to specifically enable it to build the lib). Does this bother you at all? -

I'm just like you I'm still working on it and I don't know how to connect to relationships with QDjangobq. Also, I noticed that QDjango uses API deprecated in Qt5 (I had to specifically enable it to build the lib). Does this bother you at all?
Which version you're using? I use 0.4 which works in Qt5
