12 Best Free and Open Source Linux Document-Oriented Databases
Document-based databases do not store data in tables with uniform sized fields for each record. Instead, each record is stored as a document without the need to define in advance the schema of the data. This means that any number of fields of any length can be added to a document. JSON (JavaScript Object Notation) objects are frequently used in document-oriented databases. This type of database operates on something similar to distributed hash tables.
There is a good selection of Linux document-oriented databases that are available under an open source license. This article selects our personal pick of databases which can offer better performance in your application as well as quicker development time. Here’s our verdict. All the software is free and open source. We allow Couchbase to be included as while its time-limited license is not open source, it converts back to an open source license after 4 years.
