Hypertable - A high performance, scalable, distributed storage and processing system for structured

Hypertable is based on Google's Bigtable Design, which is a proven scalable design that powers hundreds of Google services. Many of the current scalable NoSQL database offerings are based on a hash table design which means that the data they manage is not kept physically ordered. Hypertable keeps data physically sorted by a primary key and it is well suited for Analytics.

soda-for-java - SODA (Simple Oracle Document Access) for Java is an Oracle library for writing Java apps that work with JSON (and not only JSON!) in the Oracle Database

Simple Oracle Document Access (SODA) is an API which allows you to use the Oracle Database as a NoSQL JSON document store. Although SODA is particularly powerful when it comes to JSON data, data of any other type is supported as well. With the SODA architecture, your data is stored as documents, and documents are organized into collections. Each document contains the actual data, as well as additional information automatically maintained by SODA, such as unique key, last-modified timestamp, version, type, etc. SODA lets you create and store such collections of documents in the Oracle Database, and perform create, retrive, update, and delete (CRUD) operations on these documents, without needing to know Structured Query Language (SQL), or JDBC, or how the data is stored in the database. Essentially SODA provides a virtual NoSQL document store on top of your Oracle Database. Under the covers, a collection is stored as a regular Oracle Database table, and each document is stored as a row in the table. SQL access to the table using standard tools is still allowed.
