MongoDB

claimed by 10gen

MongoDB is a high-performance, open source, schema-free document-oriented data store that's easy to deploy, manage and use. It's network accessible, written in C++ and offers the following features : * Full index support, including on inner objects * Query profiling * ... [More] Replication and fail-over support * Efficient storage of binary data including large objects (e.g. videos) * Auto-sharding for cloud-level scalability (Q209) High performance, scalability, and reasonable depth of functionality are the goals for the project. Deep transaction support is not a goal of the system. [Less]

Apache CouchDB

claimed by Apache Software Foundation

CouchDb is a distributed document database system with bi-directional replication. It makes it simple to build collaborative applications that can be replicated offline by users, with full interactivity (query, add, update, delete), and later "synced up" with everyone else's changes when back online.

Morphia

Type-safe Java mapping framework for MongoDB

EclipseLink

claimed by Eclipse Foundation

The Eclipse Persistence Services Project (EclipseLink) project's goal is to provide an extensible framework that will enable Java developers to interact with relational databases, XML, and Enterprise Information Systems (EIS) in an efficient and productive manor. EclipseLink will focus on ... [More] supporting leading persistence standards including the Java Persistence API (JPA), Java API for XML Binding (JAXB), Java Connector Architecture (JCA), and Service Data Objects (SDO). [Less]

Cassandra

claimed by Apache Software Foundation

Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store. Cassandra brings together the distributed systems technologies from Dynamo and the data model from Google's BigTable. Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra provides ... [More] a ColumnFamily-based data model richer than typical key/value systems. Cassandra was open sourced by Facebook in 2008, where it was designed by one of the authors of Amazon's Dynamo. In a lot of ways you can think of Cassandra as Dynamo 2.0. Cassandra is in production use at Facebook but is still under heavy development. [Less]

Raven DB

Raven is an Open Source (with a commercial option) document database for the .NET/Windows platform. Raven offers a flexible data model design to fit the needs of real world systems. Raven stores schema-less JSON documents, allow you to define indexes using Linq queries and focus on low latency and high performance.

Kazoo Platform

Kazoo is a scalable, distributed, cloud-based telephony platform that allows you to build powerful telephony applications with a rich set of APIs. Designed to handle anything from large carrier to small countries, the Whistle infrastructure can do it all. There are no lock-ins and the software is ... [More] open-source to give you complete freedom. Services include: - Complete redundancy and failover between data centers - Complete replication of all data - Use of Map/Reduce algorithms inside NoSQL databases - Multi-master replication and caching of registrations, active channels and call lookups - Load balancing built-in - Event driven messaging for managing and using calls - A complete REST interface for implementing call flow features [Less]

Infinispan

Infinispan is an open source, JVM based data grid platform. Infinispan is a high performance, distributed and highly concurrent data structure. Also supports JTA transactions, eviction, and passivation/overflow to external storage.

OrientDB

OrientDB is a deeply scalable Document-Graph DBMS with the flexibility of the Document databases and the power to manage links of the Graph databases. It can work in schema-less mode, schema-full or a mix of both. Supports advanced features such as ACID Transactions, Fast Indexes, Native and SQL ... [More] queries. It imports and exports documents in JSON. Graphs of hundreads of linked documents can be retrieved all in memory in few milliseconds without executing costly JOIN such as the Relational DBMSs do. OrientDB uses a new indexing algorithm called MVRB-Tree, derived from the Red-Black Tree and from the B+Tree with benefits of both: fast insertion and ultra fast lookup. [Less]
