Hi John I think, I understand what you will to say.... > Sqlite is a single file shared between users just like a word processing > file shared between multiple users. It is not a DBMS server and just > uses the regular fcntl type file locks. but... I want try to ask again... ;-) SQLite handles the File-Lockings as a physical Locking during the writings to File and Disk. (Is it so?) I do my own logical Locking during the Edit of a Record and then reflect to the Busy-State if the changes will be saved to disk. The different point of views are intended from a logical Lock during Edit and a physical Lock during storing the Data to Disk. A logical Locking can hold it for a long time, several minutes, to a hour ... so long the user need to hold this Record for Editing. But there is during editing no affect to DB. This will done very well in my Logical-Locking- Concept. The physical File-Locking needs only milliseconds, even to write changes to Disk, if DB Ready and not Busy. Now then...if the User-Edit endet, the changes will be saved to File and written to Disk, and that is controlled bei File- Locking through SQLite, so that multiple Diskwritings to one DB do not end in a collision. Is that accurately described? Greeting from Germany Anne -- "Feel free" – 10 GB Mailbox, 100 FreeSMS/Monat ... Jetzt GMX TopMail testen: http://www.gmx.net/de/go/topmail
