Overview

Essentials you should know about MongoDB.

Structure

  • MongoDB is a schema-less and document-oriented NoSQL database.

  • MongoDB uses documents instead of tables.

  • Mongo DB combines documents to collections.

  • The documents may have different structures. The structure is created during runtime.

Examples - database content

  • In the case of PLOSSYS Output Engine, MongoDB contains the data of printers and jobs.

  • In the case of SEAL Operator, MongoDB contains the complete data, e. g. documents, panels, tasks, user settings and other.

Securing MongoDB

You may use different ways to secure MongoDB:

Hint - strongly recommended

For security reasons we strongly recommend configuring the TLS encryption.

For enhancing the security activate the user authentication for MongoDB in addition.

MongoDB in a Cluster

If you run MongoDB in a cluster, the data stored in the database are distributed. Therefore, a failure of a MongoDB node does not affect the integrity of the database.

For details on the configuration MongoDB in a cluster, refer to

Hint - automatic synchronization

The database within a cluster is synchronized automatically. Therefore you need to add or change data on one of the cluster servers only.
