I've been studying the advantages of using a graph-driven database and when I went to evaluate the cost for use at work, I did not find much information. I mainly studied Neo4j , which for startup is free, but for more professional use it is paid and has no value on the site.
Is there a free graph-oriented database for commercial use?
If it does not exist, does anyone know about any of these values?
Research on DB Arango, it is free and open source. link There are many tips on how to use it here: link And if you want to search for more options, in this link there is a comparison between the databases oriented to graphs, the cool thing is that for the most popular users giving the opinion of each of them. link
Neo4j has two versions:
Community edition : distributed under GPLv3 license.
Enterprise Edition : distributed under AGPLv3 license.
The enterprise version has extra features and functionality. For example, in the enterprise version you can create uniqueness constraints on properties (eg, the nome property of nodes with :Usuário label must be unique). Other features, such as hot backups , are also only available in the Enterprise version. You can view the features of each version in detail here .
If you need the enterprise version and your business fits into some requirements, you can be a part of the Neo4j StartUps program >:
