Audit Result interface

The previous article went through how to implement an Auditor to collect audit data from the results of either the Source Engine or the Target Engine when it has processes a Business Entity. These auditors hand back the collected audit data to the Runtime that will store it next to the Business Entity it self. The Runtime will take care of all the necessary housekeeping toi keep things consistent - even when the migration of the Business Entities are iterated as a natural part of the migration progress, 

So far so good. This article deals with how to get the audit data unloaded from the Runtime so it can take part in your over all reconciliation.

The Audit unload is initiated on request from the Administration / Manage panel in the Portal Operations:

 When the Audit Unload job is submitted, it will retrieve the collected audit data for all Business Entities and hand to an extension class that derives from the public abstract interface class AuditResult:

[ExtensionType(ExtensionType.AuditResult)]
public abstract class AuditResult : ExtensionBase<IAuditResultContext>
{
  public abstract void Enumerate(IEnumerable<IAuditResultItem> items);
}

When inplementing an AuditResult extension class, you must override the abstract Enumerate method. This method receives an IEnumerable of IAuditResultItem, one for each Business Entity:

public interface IAuditResultItem
{
  long ItemId { get; }
  Guid EntityID { get; }
  string Name { get; }
  Guid BusinessEntityID { get; }
  string BusinessEntityName { get; }
  string PartitionValue { get; }
  string SourceKey { get; }
  string MigrationKey { get; }
  bool ExportSucceeded { get; }
  bool ImportSucceeded { get; }
  string SourceAuditData { get; }
  string TargetAuditData { get; }
}
