DescriptionWide-column store based on ideas of BigTable and DynamoDB infoOptimized for write accessAll 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.A highly scalable full ACID SQL database with fast NoSQL data ingestion and GIS capabilitiesGlobally distributed, horizontally scalable, multi-model database serviceOpen source search engine for searching in data from different sources, e.g. relational databases
