I'm using web2py in replacement of an access application I had before. It aims at providing a simple production record process for a plastic injection factory (less than 35 employees). It is binded via csv read to our ERP Produflex (FoxPro database). Now it supports production performance and quality related actions for end users. It is closely binded to Produflex so I do not think the source is interesting. Moreover as a non programmer I did not follow the good practices so I think my code is a bit awful (but documented). I tried before Joomla, Plone (with archgenxml). I must add that Plomino for plone (based on Lotus domino) is a very nice product. But I finally realised I needed a lower and faster access to my application. I also wanted to keep my data easely readable from outside the application. I lookforward to adding more stuff like consulting product specification (stored on external files like word, excel), but without breaking the existing structure.
Best regards JmiXIII PS : sorry dor my english
