At first sight, it is simple task: "We need 1C". But inexperienced specialists usually have problems with it. The reason is clear: users don't divide 1C:Enterprise a platform and its configuration. Lets talk about differenses.

The configuration is set of system algorithms. Configuration defines: accounts printing form design, VAT calculating formelas, current user rights etc.
Data is the usual database, which structure corresponds to the the 1C:Enterprise configuration logic.
