Hi, Thanks for the responses guys. I'll clear up my question a bit more maybe, the application which data I'm accessing doesn't store it's information in a database, it only stores it in the application at runtime. I did think to ask to have a module send the data to my application like what you guys suggested, but then that doesn't make my application standalone, or does it? In the sense that, a module from the bigger application has to be created to send whatever data I need, so really my .py application has to be imported into the bigger application, hence not making it standalone. Or am I trying to make things a bit too complication for myself? I guess I was just thinking of a way for my application to be more versatile and can be used with other similar main applications, sort of as a service application.
