Is ObjectDB a NoSQL Database?

ObjectDB is a unique NoSQL database. It doesn't have the known disadvantages and limitations of NoSQL technology, which are weak query capabilities and lack of ACID (atomicity, consistency, isolation, durability).

Unlike other NoSQL solutions, ObjectDB provides full support of rich complex queries, using two standard Java query languages: JPQL (Java Persistence Query Language) and JDOQL (JDO Query Language). The power of these query languages is equivalent to the power of SQL, but they are easier to use in object oriented languages such as Java.

In addition, unlike most other NoSQL databases, ObjectDB supports full ACID (atomicity, consistency, isolation, durability). Therefore, ObjectDB can be used in applications that cannot use conventional non ACID NoSQL databases because of a requirement for a very high level of consistency.

Getting Started

ObjectDB is very easy to use. Follow the Getting Started Tutorial and the Quick Tour manual chapter and in minutes you may be able to write and run first Java programs against ObjectDB.

Prior knowledge or experience in database programming (SQL, JDBC, ORM, JPA, etc.) is not required, but some background in using the Java language is essential.
