Java

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

The InterSystems IRIS® Persister for Java is designed to ingest data streams and persist them to a database at extremely high speed. Each thread-safe Persister instance consumes a data stream, serializes each record, and writes each serialized record to an output buffer or pool of buffers. Each buffer in a pool maintains a separate connection to an InterSystems IRIS server.

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.

The InterSystems IRIS® Native SDK for Java is a lightweight interface that allows Java applications to access powerful InterSystems IRIS resources formerly available only through ObjectScript:

• Call ObjectScript and Embedded Python methods and functions

  Call any embedded language classmethod from your application as easily as you can call native Java methods.

• Manipulate embedded language objects

  Create proxy objects in your applications to control embedded language class instances. Call instance methods and get or set property values as if the instances were native Java objects.

• Perform transactions in the same session and context as server applications

  Your applications can work together with embedded language applications, performing transactions in the same session and context, using the same connection. The connection is fully reentrant, so all applications can join or leave the session as necessary.

• Work with Global Arrays

  Directly access globals, the tree-based sparse arrays used to implement the InterSystems multidimensional storage model.

Native SDKs are also available for Python, .NET, and Node.js.

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