XEP API for .NET
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.
