n2pdf Archive uses this database for two purposes. On the one hand, the jobs that have to be executed periodically are stored in this database: the Server Task monitors this database, and starts jobs when their time interval dictates that they have to be run. On the other hand, the database offers the option of defining one-off jobs and starting them. When a job is started (regardless of whether it is a scheduled or one-time job), the job document is always copied from this database to the inbox database. In fact, n2pdf Archive will not start processing the job until it is in the inbox database.
