1) Jindi SMS Service middleware exposes four shared database tables to the customer's system: the task table to be sent (T_SendTask), the sent record table (T_SentRecord), the receipt record table (T_RecRecord), and the event log table (T_EventLog);

2) When the customer system needs to send SMS, it only needs to write the receiving mobile phone number, sending content, sending priority, sending time and other information into the "task list to be sent";

3) Jindi SMS service middleware will automatically poll the "task table to be sent" at regular intervals, automatically send the SMS, generate a sending result record for each sending target and split SMS and write it into the "sent record table", and the customer system can query the final sending status;

4) Jindi SMS service middleware will automatically receive the replied SMS and write it into the "Receipt Record Table", and the customer system can read the received SMS regularly for processing;

5) The middleware of Jindi SMS service will write the generated log information into the "log table", and the customer system can obtain the system running status according to the log information at any time.

6) The most commonly used interface of Jindi SMS middleware is the database interface mode, and its working mode is as follows:
