You might want to look at https://www.xcase.com/demo.php. It's not free, but it's quite a bit cheaper than PowerDesigner, as far as I can tell. I've used earlier versions, but lately I've had easy access to Visio, so have continued with that instead of investing in xCase. |

There's a difference between compiling and targeting.

StringBuilder is better for building up a string from many non-constant values.
