Answer:

The statement regarding the five phases of the database lifecycle, which include Planning, Analysis, Detailed System Design, Implementation, and Maintenance, is True.

Explanation: The database lifecycle (DBLC) indeed consists of five essential phases: Planning, Analysis, Detailed System Design, Implementation, and Maintenance. These phases play a crucial role in the effective development and management of databases within an organization.

In the Planning phase, organizations gather initial requirements and define the scope of the database project. During Analysis, data requirements and constraints are thoroughly understood and documented. The Detailed System Design phase then translates these requirements into a detailed database schema for implementation.

Implementation involves creating the actual database based on the design specifications laid out in the previous phases. Lastly, Maintenance encompasses tasks like performance tuning, updates, and modifications to ensure the database continually meets the needs of its users.
