Clients that access the X-Machine can be tools (e.g. Tamino Interactive Interface or Tamino Data Loader), applications that use the Tamino APIs, or applications that use HTTP directly without a Tamino API.

Communication issues of other components (e.g. Tamino Manager) are not discussed here. Traditionally, the X-Machine is accessed via a web server; from Tamino 4.1, direct (webserverless) access is also possible. It makes no difference to the X-Machine whether requests are shipped with or without a web server.

The user's session state in the database is not related to any communication machinery. Requests relating to a single database session can be issued from various machines via various transport layers, as long as they contain the appropriate session ID and session key.
