Final answer:
Database management encompasses summarization, storage, retrieval, and deletion. All these are essential components of database management tasks, and there is no option listed that does not belong to database management activities.
Step-by-step explanation:
Database management tasks include a range of activities that ensure the proper maintenance and utilization of data within a database system. These tasks are critical for the organization and accessibility of data. The tasks commonly included in database management are:
- Summarization: Summarizing data to provide an overview or reports for analysis.
- Storage: Safely storing data in the database so that it remains intact and is available for future retrieval.
- Retrieval: Accessing or fetching the stored data upon request.
- Deletion: Removing data that is no longer needed or is to be discarded according to policies or regulations.
Hence, all the options listed (summarization, storage, retrieval, and deletion) are indeed components of database management tasks. There is no option listed that is not a part of database management.
