About This Book

This book explains how to access InterSystems databases from .NET client applications. It contains the following sections:

There is also a detailed Table of Contents.

This book describes how to use the IRISClient .NET assembly, which provides two different but complementary ways to access InterSystems databases from a .NET application:

  • The ADO.NET Managed Provider — is InterSystems implementation of the ADO.NET data access interface. It provides easy relational access to data using the standard ADO.NET Managed Provider classes (see “Using ADO.NET Managed Provider Classes”).

  • The Entity Framework Provider — is the InterSystems implementation of the object-relational mapping (ORM) framework for ADO.NET. It enables .NET developers to work with relational data using domain-specific objects (see “Using the Entity Framework Provider”).

The IRISClient assembly is implemented using .NET managed code throughout, making it easy to deploy within a .NET environment. It is thread-safe and can be used within multithreaded .NET applications.
