JDBC API for relational access

The JDBC (Java Database Connectivity) API enables you to perform operations on InterSystems IRIS® data using SQL.

InterSystems IRIS includes a high-performance Type 4 JDBC database driver that complies with the JDBC 4.2 specification. The driver accepts the following connection URL (or connection string):

jdbc:IRIS://ipAddress:superserverPort/namespace

where the variables represent the InterSystems IRIS instance host’s IP address, the instance’s superserver port, and a namespace on the instance

XEP API for high-speed object access

The XEP (Express Event Persistence) API provided by InterSystems enables Java applications to store and retrieve objects that adhere to simple or moderately complex schemas from InterSystems IRIS®. More specifically, XEP projects Java objects as persistent events, which are persistent database objects that store the state of Java objects.

XEP is optimized for applications that must handle high throughput, such as transaction processing applications.If you use XEP for object persistence, you can avoid the overheard of object-relational mapping.

Native API for direct access to data

The Native API for Java provides direct access to globals, the tree-based sparse arrays that form the basis of the InterSystems multidimensional storage model and underlie the InterSystems IRIS® object and SQL interfaces. The Native API exposes these native data structures, which provide very fast, flexible storage and retrieval. The Native API also enables your Java application to work with InterSystems IRIS objects as easily as if they were native Java objects, and includes the ability to call InterSystems IRIS class methods and routines.

Hibernate API for complex object data models

The Hibernate API is a third-party tool that maps complex Java data classes to InterSystems IRIS®. InterSystems IRIS includes a Hibernate dialect.
