atabase logging in Dynamics 365 Human Resources and Finance & Operations is a history of actions executed by the system, based on CRUD (Create Update Delete). Database logging is needed to track the specific types of changes to the system. The operations that can be tracked with database logging are: insert, update, delete and rename key.
When we configure the logging for a table or field, a record of every change to that table or field is stored in the database log table called sysdatabaselog, located in the environment database. Database logging can be used to create an auditable record of changes to specific tables that contain sensitive information.
