The APIs and syntax vary a bit in names but philosophically and design-wise it's very much the same. EOModeler will not work, there's a different tool called "Cayenne modeler", a standalone app.
My primary DBs are MySQL and Postgres, both work fine with Cayenne. It's an established tool to say the least. I've been using it for a few years now and interestingly enough, I don't recall encountering a bug (even if I'm still always using snapshot releases) - hugi > On 26 Jun 2020, at 19:32, Jesse Tayler <jtay...@oeinc.com> wrote: > > > so, my simple EOF/ERXKey qualifiers and stuff would work, I’d use EOModeler? > > MySQL works fine it sounds, I’m using AWS stuff myself… > > > >> On Jun 26, 2020, at 3:27 PM, Hugi Thordarson <h...@karlmenn.is> wrote: >> >>> Ok, so are all the cool guys using Cayenne now then? >> >> I've seen some pretty cool guys use it but I also use it. >> >> >>> I'm sure I should read some page about it rather than waste everyone’s time >>> reiterating why it’s better and why we should be moving to that sort of >>> thing etc. >> >> It's awesome in so many ways.
