Experience .NET and InterSystems IRIS
Connect a .NET application to InterSystems IRIS
ADO.NET for relational access
ADO.NET is a data access technology from the Microsoft .NET Framework that enables programmers to access data sources in InterSystems IRIS for Health™ with SQL in a standard, reliable way.
XEP API for high-speed object access
The XEP (Express Event Persistence) API provided by InterSystems enables .NET applications to store and retrieve objects from InterSystems IRIS for Health™. More specifically, XEP projects .NET objects as persistent events, which are persistent database objects that store the state of .NET 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 .NET 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 for Health™ 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 .NET application to work with InterSystems IRIS for Health objects as easily as if they were native .NET objects, and includes the ability to call InterSystems IRIS for Health class methods and routines.

Entity Framework for object-relational mapping
Entity Framework is a mapping tool that enables you to map .NET objects to relational tables in InterSystems IRIS for Health™ and eliminates the need for most of the data-access code that developers must typically write.
