1.4.3. Types of component interactions

To build an information system, all system components must be interconnected, ensuring their interaction. The following interactions between components are distinguished:

1. Direct connection. In this case, the client application connects directly to the database file (in file mode) or 1C:Enterprise server.
2. Connection via a web server. In this case, the client application connects to the web server, and the web server extension performs all further data access activities directly with the database (in file mode) or via the application server (in client/server mode).
3. Mobile platform. It is a special 1C:Enterprise version to be installed on a mobile device running any supported mobile operating system.

An information system often supports multiple access types. For example, the internal network of an enterprise might use a direct connection, while remote users access the same infobase via a web server, and external users can use mobile devices to get the required data.
