ODBC service can easily upload data to the cloud. It will be load the config file and the last data of system record when the service does initialization. The last recorded data Compare with data of database (CSV file) to decide whether to retain index value or not. Every time new data is detected from database, the service will upload new data to cloud and record the last data that is prevent repeat to upload when the service is restarted.


User need observe the following points:

  1. Append data to database: User write data to database (CSV file) please add data after the last index.
  2. Add database (CSV file) is invalid at runtime service.
  3. Recycle: If user wants to clear data in database please start from the first index.
  4. Have need of timestamp item and put in the fisrt column about data of database.
  5. Don't prohibit reading permission when user write data to database.
