An interaction is an action of a user through a screen, such as running a query in a form, registered for the [[Invantive Studio/Repository/Concepts/Audit Trail|audit trail]]. Changes made directly through the business objects are not interactions; they appear as [[Invantive Studio/Repository/Security/Transactions|transactions]]. The interactions are listed under "Security" as "Interactions". Interactions are read-only, so that misuse can be detected afterwards. ## Fields The details of an interaction show these fields: - "User name": The code with which the user logged on. - "Module": Name of the module installed. - "Machine": Name of the workstation used to access the application. - "Query": The query or data manipulation SQL-statement executed. - "Action": The executed SQL action (select, insert, update or delete). - "Interaction Number": Unique number of the interaction. - "Time": Time of the RDBMS server at which the event occurred. - "Last Transaction Number": Number of the last completed transaction. This information can be used to reconstruct complex interactions and changes through time. - "Session-ID": Unique ID of the session executing the interaction.
