Обсуждение: Avoiding re-inventing a wheel
I need to expand my client relation management/sales tracking application from its existing python3/Qt5/SQLite3 version to a more capable one built on a postgres backend. (For the record, I've been using postgres and sqlite on linux for almost 20 years now so I'm comfortable with both.) Before I end up re-inventing this wheel I'd like to learn if someone has such a tool available and is willing to let me copy it for my inhouse use. If not, I'd appreciate opinions on whether I should write the application in python (with wxPython as the GUI) and use postgres as the backend or build it primarily with postgres with python as the middleware and something for the UI. All my previous science/business applications have been written in python and pass embedded SQL to the postgres back end; I've not tried to use all the postgres capabilities to make development quicker and easier. Your thoughts? Rich

Alright. As to your other questions, it depends. Is your existing application sufficiently modular, abstracted that you can migrate portions? Or are the various levels tightly coupled and you are looking to start from scratch? > > Rich > > -- Adrian Klaver adrian.klaver@aklaver.com

Yet, I think that I found a solution that will work better than that that. There's a tool called XRMS that appears to have everything I need and want without extras I don't need. But, it has apparently not been updated in a decade. While I prefer stand-alone applications built with GTK+ or wxPython/Phoenix to those built using a browser-based UI, it should take me less time to update this PHP application to work with postgres (I just downloaded and installed adodb-5.14) and fix as necessary than to start over using the schema in XRMS. I need to use the CRM to help me bring in more business and writing applications, while fun, does not produce revenue for me. I don't know PHP but will find resources to learn what I need; if there are ways to better integrate postgres with PHP I'd certainly like to learn about them. As always, I look forward to learning from those who know more than I do. Thanks, Rich
