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 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 for Health™ 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 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.
