Data Domains & Information Objects

Background: 

The question is around Data Domains and Information Objects.  The data domains serve as a grouping of data elements.  Where the Information Objects are the elements within that domain.  Example below is from a PDI with loaded sample data.

The Information Object CIs are related to the Business Application.  The Business Application an entry defining information about an application the company purchased.  The Application Services is the instances of that application.  

 

Example:

Business Application: 

  • ServiceNow

Application Services:

  1. ServiceNow - NA Prod
  2. ServiceNow - NA Test
  3. ServiceNow - NA Dev
  4. ServiceNow - EMEA Prod
  5. ServiceNow EMEA Test
  6. ServiceNow EMEA Dev

The Business Application is related to these Application Services.

 

Now I need to know what type of information is stored on Applications.  Documentation points to align information objects to the Business Applications.  Screen shot below is demo data from the same PDI with loaded data.

Question/Issue:

You always want to simplify the number of data review points.  However, by putting that relationship at the Business Application record doesn't realistically identify where that data is.  If you don't have an automated method to determine it, it feels like 1 more layer lower would be accurate.  So - at the Application Service, identify the information Objects as there are instances that do not have the same data elements due to regulatory alignment.  GDPR may limit the system from having certain data for EMEA while North America may have some of the elements.  Even within the regional instance, the pre-prod instances may not have these elements.

 

Application Services:

  1. ServiceNow - NA Prod - Related Information Object
  2. ServiceNow - NA Test - Related Information Object
  3. ServiceNow - NA Dev - N/A
  4. ServiceNow - EMEA Prod - N/A
  5. ServiceNow EMEA Test - N/A
  6. ServiceNow EMEA Dev - N/A

 

What is ServiceNow's perspective on this?  If the Information Object isn't mapped at the Business App but at the Application Service?  Are there implications to other functionality in the tool like IRM?

FYI: Discovered database (catalogs) are often not stored in cmdb_ci_db_catalog or extended of this.

There is cmdb_ci_database (where many different types of cloud database CIs are placed), and cmdb_ci_cloud_database (and extended of this) and cmdb_ci_db_mssql_database (both extended of cmdb_ci_db_instance), and possibly also more.

A bit of a mess, unfortunately, so don't just go looking in cmdb_ci_db_catalog for your database (catalogs).

Hi @Mark Bodman 
You wrote "there is a CMDB relationship model documented if you choose to relate that conceptual, to logical, to physical data, here. I'm not aware of how many customers actually implement this, as it would require a robust discovery and physical model to be captured."
I assume you mean relating the Information Object CIs to the Database (catalog) CIs.
As the Database (catalog) CIs are dynamic in nature, is this possible to implement in practice in a large company with many databases?
