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 5, MongoDB contains the data of printers and jobs.
  • In the case of SEAL Operator/SEAL Print Client, MongoDB contains the complete data, e. g. documents, panels, tasks, user settings and other.

Database Backup

You may use different ways to back up your database, for example:

  • Copy the database files
  • Call the mongodump program

Literature - database backup

For further information, refer to the original MongoDB documentation.

Access Methods

You may use different ways to access your database:

    For more information, refer to the original MongoDB documentation.

Caution - writing

Be careful when writing into the database!

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.
