Interesting article posted on NoSQL-database.org, listing 150 databases. Here are some highlights.
Databases are categorized in the following categories:
- Wide Column Store / Column Families
- Document Store
- Key Value / Tuple Store
- Graph Databases
- Multimodel Databases
- Object Databases
- Grid & Cloud Database Solutions
- XML Databases
- Multidimensional Databases
- Multivalue Databases
- Event Sourcing
- Network Model
- other NoSQL related databases
- unresolved and un-categorized
Example of graph database representation
Here are the databases from the first category:
- Hadoop / HBase - API: Java / any writer, Protocol: any write call, Query Method: MapReduce Java / any exec, Replication: HDFS Replication, Written in: Java, Concurrency: ?, Misc: Links: 3 Books [1, 2, 3]
- Cassandra - massively scalable, partitioned row store, masterless architecture, linear scale performance, no single points of failure, read/write support across multiple data centers & cloud availability zones. API / Query Method: CQL and Thrift, replication: peer-to-peer, written in: Java, Concurrency: tunable consistency, Misc: built-in data compression, MapReduce support, primary/secondary indexes, security features. Links: Documentation, PlanetC*, Company.
- Hypertable - API: Thrift (Java, PHP, Perl, Python, Ruby, etc.), Protocol: Thrift, Query Method: HQL, native Thrift API, Replication: HDFS Replication, Concurrency: MVCC, Consistency Model: Fully consistent Misc: High performance C++ implementation of Google's Bigtable. » Commercial support
- Accumulo - Accumulo is based on BigTable and is built on top of Hadoop, Zookeeper, and Thrift. It features improvements on the BigTable design in the form of cell-based access control, improvedcompression, and a server-side programming mechanism that can modify key/value pairs at various points in the data management process.
- Amazon SimpleDB - Misc: not open source / part of AWS, Book (will be outperformed by DynamoDB ?!)
- Cloudata - Google's Big table clone like HBase. » Article
- Cloudera - Professional Software & Services based on Hadoop.
- HPCC - from LexisNexis, info, article
- Stratosphere - massively parallel & flexible data analytics platform, API: Java, Scala, Query Method:expressive data flows (extended M/R, rich UDFs, iteration support), Data Store: independent(e.g., HDFS, S3, MongoDB), Written in: Java, License: Apache License V2.0, Misc: good integration with Hadoop stack (HDFS, YARN), source code on Github
