Understanding the Data Flow

This lesson teaches how data flows through the Harmony system.

Flow of Operation

Data flows (from right-to-left) in the diagram below.



  1. Employees clock-in at one of the terminals (on the right).
  2. The terminals are connected online to the communication server running SY-Server software.
  3. SY-Server receives queries from the terminal and sends requests to the Harmony server, or receives data and enters it into the Harmony data base.
  4. Harmony users (on the left) connect to the Harmony server to view and edit data. Web Clients (running E-Harmony) connect via the IIS server.
