Article

Represents a source of business data, business logic, or both. SAP R/3 IDES, Siebel 7.5, and AdventureWorks SQL Server 2000 sample database are examples of LobSystem objects.

Syntaxe

'Déclaration
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel:=True)> _
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel:=True)> _
Public Class LobSystem
    Inherits MetadataObject
'Utilisation
Dim instance As LobSystem

[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel=true)] 
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel=true)] 
public class LobSystem : MetadataObject

Remarques

The LobSystem object derives from the MetadataObject base class. Each LobSystem object has a unique name and is of a certain type: either Database or Web Service. The Business Data Catalog accesses systems of the same type by using the same provider. For example, AdventureWorks is a Microsoft SQL Server database, and the Business Data Catalog accesses it and all SQL Server databases through Microsoft ADO.NET. SAP R/3 IDES is an SAP R/3 system, and the Business Data Catalog accesses it through the Web Services proxy, as it does with the Siebel 7.5 system.

Exemple

This example shows how to browse the metadata repository and get an LobSystem object and an Entity object.

Prerequisites

Ensure a Shared Service Provider is already created.
Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.
Make sure the LobSystem object and entity names referenced in the example exist in the Business Data Catalog. Use valid names.
