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® 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®. 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 SDK for direct access to data

The Native SDK 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® object and SQL interfaces. The Native SDK exposes these native data structures, which provide very fast, flexible storage and retrieval. The Native SDK also enables your .NET application to work with InterSystems IRIS objects as easily as if they were native .NET objects, and includes the ability to call InterSystems IRIS 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® and eliminates the need for most of the data-access code that developers must typically write.
