6. Data Synchronisation Issues Large data volumes – 20,000 customers – 40,000 products – 100,000 sales order lines Long records in main files – 150MB of data to compare/synchronise Slow upstream Internet connection from the ProMaster server

7. Optimise APPX/Net Performance Avoid BEG READ / END READ loops – Use READ / READNEXT instead Only read required records once Keep separate “modifications” files on server Allow users to decide what to synchronise Relocate the ProMaster server! Cache files do not work over APPX/Net  Can read only one record at a time 
