Example of usage:
// OPEN THE DATABASE
ODatabaseDocumentTx db = new ODatabaseDocumentTx("remote:localhost/petshop").open("admin", "admin");
// CREATE A NEW DOCUMENT AND FILL IT
ODocument doc = new ODocument("Person");
doc.fIEld( "name", "Luke" );
doc.fIEld( "surname", "Skywalker" );
doc.field( "city", new ODocument("City" ).field("name","Rome").fIEld("country", "Italy") );
// SAVE THE DOCUMENT
doc.save();
// QUERY THE DOCUMENT
List<ODocument> result = database.query(
new OSQLSynchQuery>("select * from person where city.name = 'Rome'")).execute();
// PRINT THE RESULT SET
for( ODocument d : result ){
System.out.println("Person: " + d.field( "name" ) + d.fIEld( "surname" ));
}
db.close();
Deeply scalable Document based DBMS. It's the basic engine of all the Orient products. It can work in schema-less mode, schema-full or a mix of both. Supports advanced features, such as ACID transactions, indexing, fluent and SQL-like querIEs. It handles natively JSON and XML documents.
Main features:
* Extremely light: less than 400Kb for the full server.
* Run on any platform: All the engine is 100% pure Java and can run on Windows and Linux and any system that supports the Java5+ technology
* Super fast: On common hardware* stores up to 150.000 (one-hundred-fifty-thousands) records per second, 13 billions per day.
* Transactional: Compliant with ACID tests, supports Optimistic (MVCC) and Pessimistic transaction modes
* Local mode: Direct Access to the database bypassing the Server. Perfect for scenariOS where the database is embedded.
* Easy Java APIs: Learn how to use it in 15 minutes.
