BaseEntity - Auditable Entity and Auditing

Hi, 

I am making slow progress with my first CAB app. I used the Wizard and then used the "IdeaBlade Object Mapper" to attach to my own database (in which I have both my own business tables as well as several of the "application" tables I copied from the IdeaBlade Tutorial DB). 

The questions I have relate to the implementation of Auditing... I didn't see any explanation of Auditing in the PDF doc nor on the website/forums.

So, to the questions: 

1. What is the difference between "BaseEntity" and "AuditableEntity"? My guess would be that any BOs I want audited should inherit from "AuditableEntity"? 

2. Since I deleted the "Employee" class, I get a build error at this point (AuditableEntity):

    /// <summary>Set the global entity "Audit Columns" for this application.</summary>
    /// <remarks>
    /// Modeled on the columns in the Employee entity.
    /// </remarks>
    private static void SetGlobalAuditColumns() {
      AuditColumnManager.SetGlobalAuditColumns(
        Employee.CrtnUsrIdEntityColumn.ColumnName,
        Employee.CrtnTsEntityColumn.ColumnName,
        Employee.ModUsrIdEntityColumn.ColumnName,
        Employee.ModTsEntityColumn.ColumnName
        );
    }

I assume that this has to do with assigning the "who created or modified this record" data to each row...

Since I kept the Users table, I assumed that I could use that to determine the "who" rather than the Employee, so I changed the code to:

private static void SetGlobalAuditColumns() {
      AuditColumnManager.SetGlobalAuditColumns(
        SecurityUser.CreatedByUserIdEntityColumn.ColumnName,
        SecurityUser.CreatedDateEntityColumn.ColumnName,
        SecurityUser.ModifiedByUserIdEntityColumn.ColumnName,
        SecurityUser.ModifiedDateEntityColumn.ColumnName
        );

I was able to build/run the application, but I just want to be sure I am on the right track here...

Thanks!

Heather
