Using the Caché Managed Provider for .NET - InterSystems ...

The Caché Managed Provider Solution• Using Caché Proxy Classes provides instructions for creating proxy classes, and gives concreteexamples of how to use proxy objects in your code.• Caché Managed Provider Class Reference provides details on the classes and methods availablewith the Caché Managed Provider.Throughout this document, we use code examples taken from the bookdemos project located in\Dev\dotnet\samples\bookdemos (see Default Caché Installation Directory for thelocation of on your system). For details on how to set up and run this and othersample programs, see The Caché .NET Sample Programs.Web Services (SOAP) can also be used to exchange data between Caché and .NET client applications.For more information, refer to the following online documents:• Using SOAP and Web Services with Caché in the Caché Language Bindings section.• Caché Managed Provider for .NET Tutorial in the Caché Tutorials section.1.1 Caché .NET Binding ArchitectureThe Caché .NET binding gives .NET applications a way to interoperate with objects contained withina Caché server. These objects can be persistent objects stored within the Caché object database or theycan be transient objects that perform operations within a Caché server.The Caché .NET Binding consists of the following components:• The Caché Object Server — a high performance server process that manages communicationbetween .NET objects and a Caché database server using standard networking protocols (TCP/IP).Caché uses a common server for .NET, C++, Java, Perl, Python, ODBC, and JDBC access.• The InterSystems.Data.CacheClient assembly — a set of .NET classes that implement all thefunctionality of the .NET classes created by the Caché Proxy Generator. It also provides a set ofproxy classes for a few Object Server classes that are projected differently to make them fit intothe framework of the .NET standard library.• The Caché Proxy Generator — a set of methods that generate .NET classes (source files or completeassemblies) from classes defined in the Caché Class Dictionary. Several different interfaces areavailable (see Generating Caché Proxy Classes).The Proxy Generator can create .NET proxy classes for any class in the Caché Class Dictionary. Theproxy classes contain only managed .NET code, which the Proxy Generator creates by inspecting theclass definitions found in the Caché Class Dictionary. Instances of the .NET proxy classes on the clientcommunicate at runtime (using TCP/IP sockets) with their corresponding Caché objects on a Cachéserver.
