What is a necessary action to account for newly added columns in a data model?

To effectively account for newly added columns in a data model, synchronization with the database is essential. This process ensures that the data model reflects the current structure and contents of the underlying database, including any new columns that have been added. Synchronization typically involves refreshing the schema and pulling in any changes that have occurred since the last update.

When synchronization is performed, it assesses the current schema of the database and updates the data model accordingly, which includes recognizing newly added columns. This action is crucial because the data model must accurately represent the database to ensure that reporting, analysis, and other data operations can be performed on the most current data structure.

While other choices involve elements related to working with data models, they don't specifically address the necessary action of reflecting recent schema changes due to newly added columns in the most efficient way.
