When to use DataSnap?

  • A small number of concurrent clients
  • Supports authentication and authorization
  • Support for communication filters
    • Compression and Encryption filters included
  • Callback functionality – Servers can notify selected or all connected client applications by sending information to the callback channels that something interesting happened on the server
