Oguz Sariyildiz,
You can edit feature classes in a file geodatabase while other users can only view or read data.
you can share a file geodatabase folder as read-only with Windows Explorer. In this case, the read-only user can display and query but not edit the data. Also, users with write access can modify the data while others are reading it. When those reading the data refresh their map display, any changes saved by other users are updated in the ArcGIS client session of the reading user. Refresh never brings in unsaved edits, so it is not possible for a user to read changes made by another user that have not been saved. If you want to prevent other users from accessing data while you are editing it, unshare the folder before modifying the data.
