Ok, thanks for all your replies!!! First, i was asking to understand...before to start development in a wrong direction.
I don't have experience with SQLite and even less on a network share. I would understand if corruption is a remote possibility or a certainty. Someone said that Access suffer the same problem... In my experience even with 20-30 clients with low concurrency (management software) MS Access file corruption is a rare event. (the article you linked refer to a bug with an hotfix) I can't use Access in my case because my application is x64. About VistaDB it support use on network share look at http://www.gibraltarsoftware.com/Support/VistaDB/Documentation/WebFrame.html#VistaDB_Introduction_SupportedPlatforms.html and confirmed from its support. Unfortunately i have not experiences with it....i can't say how much this is true... Other suggests are welcomed? Thanks Alessandro
