The MongoDB™ database is an open source NoSQL database management application that can manage, store, and retrieve document-orientated information. NoSQL (“not only” SQL) is a non-relational database that is used as an alternative to traditional relational databases. NoSQL databases are useful for working with data applications that involve large data processing.
The MongoDB database is made up of collections and documents in lieu of using tables and rows as in relational databases. Sets of documents are called collections, which function as the equivalent to relational database tables. Collections can contain any type of data, but the restriction is the data in a collection cannot be spread across different databases. The Thermo Fisher Scientific instrument control software utilizes a Thermo TNG database (MongoDB database type) and automatically installs it as part of the software installation.
IMPORTANT
Database collections can surpass 20 GB in size. Be sure to maintain your instrument data system and keep an adequate amount of free available disk space. Thermo Fisher Scientific recommends keeping a minimum of 100 GB of free disk space available.
The following table lists the data and retention time schedule for the information that is captured and stored in the database.
Data | Retention time (days) |
|---|---|
Nonessential instrument information | 10 |
General instrument information | 10 |
Data that are required to generate report information | 30 |
Instrument parameters | 60 |
Essential instrument configuration data | Always kept, never purged |
Database purging is performed automatically by the TNG database service. User interaction is limited to the Historical Data Retention settings that are available in the Thermo Foundation Instrument Configuration area. For details on how to set the historical Data Retention setting, see Set the Historical Data Retention.
