Information portfolio
Use the information portfolio to capture information from the assets of your organization as information objects. You can categorize the information assets and determine its business application use. You can also connect the different layers where data exists and map the layers. Mapping helps to retrieve the information and track the information flow.
Information portfolio data model
The basic data model of information portfolio is in the introduction of two tables, which are Information Object and Data Domain.
- Information object is a configuration item that displays information in an organized form. The purpose of the information object is to logically describe the type of data (or the information) that is interchanged between the application and the database. The database being the one that serves the application with data.
- Data domain is to classify or categorize the information objects.
Application Portfolio Management (APM) integrates with information portfolio by relating a business application with the database. The database provides the information to the application using an intermediary cmdb CI class called information object [cmdb_ci_information_object] table.
The business application is related with the information object by establishing Uses::Used by cmdb CI relationship. The information object, in turn, is linked to the database catalog and instances by establishing Depends on::Used by cmdb CI relationship.
APM integrates with ServiceNow Discovery that finds database applications, database instances, and database catalog. The database catalog lists all the catalog objects, or databases, discovered for an instance of a database.
Plugin activation procedure
CMDB plugin has the Information Object (cmdb_ci_information_object) CI. When APM plugin is activated, the data domain field gets added to the cmdb_ci_information_object table. The data domain field references the Data Domain table, which is included in the APM plugin.
