Sqrrl has been acquired by Amazon and became a part of Amazon Web Services. It has been removed from the DB-Engines ranking.
DescriptionAll data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.Full-featured RDBMS with a small footprint, either embedded into a Java application or used as a database server.Well established RDBMSFully managed big data interactive analytics platformAdaptable, secure NoSQL built on Apache Accumulo
