I am trying Ingres, i think it perform well. I read it license but don't under it.
I know Ingres is open source under Computer Associates Trusted Open Source License but is Ingres free for commercial use? If my application is commercial , must i open code of my application ?
I know my question is in Ingres License but i can't understand it.
Thank very much. Sorry for my english.
My understanding is that you can distribute the R3 version of Ingres with your application free of charge.
You have to distribute the Ingres software licence with it, and I believe include the source.
You do not have to include source for you application however, which is just using Ingres. Any modifications to Ingres you make however - like if you fix bugs or include additional functionality like improved checkpoints - then you have to include source.
I have a limited understanding however and you would be better off asking CA and getting legal advice in the end...
