NoSQL

NoSQL is a classification of database systems that do not support the SQL standard. These include document databases, key-value stores, and various other non-standard databases. EclipseLink supports persistence of Java objects to NoSQL databases through the Java Persistence API (JPA). EclipseLink's native API is also supported with NoSQL databases.

The NoSQL classification can also be expanded to include Enterprise Information Systems (EIS) including application databases, legacy databases, messaging systems, and transaction processing monitors.

EclipseLink's NoSQL support includes:

  • MongoDB
  • Oracle NoSQL
  • XML files
  • JMS
  • Oracle AQ
  • NoSQL and EIS data-sources that have a JCA resource adapters that supports the JCA CCI interface

There are many different ways to access NoSQL and EIS data-sources. Many NoSQL data-sources provide a Java API. For EIS data-sources, there are many third party and custom Java adapters. These APIs are normally non-standard, and low-level, similar to JDBC. EclipseLink's NoSQL support is normally built on top of such an APIs, and offers the rich, high-level and standard JPA API.

Some NoSQL data-sources support the JDBC API, and even a subset of the SQL language. Many third party vendors provide JDBC drivers for EIS data-sources. EclipseLink's regular JPA support can be used with any compliant JDBC driver.

Some NoSQL data-sources may support the Java Connector Architecture.
