Each script corresponds to a particular event in the synchronization process. You write a script only when some action must occur. All unnecessary events can be left undefined.
The two principal parts of the process are the processing of uploaded information and the preparation of rows for downloading. If rows are uploaded from a remote table you must define the appropriate upload script(s). If a table is to have rows downloaded via SQL then both the download_cursor and download_delete_cursor scripts must be defined.
The MobiLink server reads and prepares each script once, when it is first needed. The script is then executed whenever the event is invoked.
