In many modern applications the database side is realized using polyglot persistence – store each data format (graphs, documents, etc.) in an appropriate separate database.
This approach yields several benefits, databases are optimized for their specific duty, however there are also drawbacks:
* keep all databases in sync
* queries might require data from several databases
* experts needed for all used systems
A multi-model database is not restricted to one data format, but can cope with several of them.
In this talk i will present how a multi-model database can be used in a polyglot persistence setup and how it will reduce the effort drastically.
