CompTIA DataSys+ (DS0-001)Database Management and MaintenanceEasy
A data engineer is tasked with creating a comprehensive document for a new data warehouse, detailing its schema, data models, data lineage, and data definitions. This documentation will be used by data analysts, developers, and future administrators. Which type of documentation is the engineer primarily creating?
- ADisaster Recovery Plan
- BOperational Runbook
- CUser Manual
- DDatabase Design Document
Show answer & explanationAnswer & explanation
Correct answer: D. Database Design Document
A Database Design Document (or Data Model Document) specifically details the structure, relationships, and definitions of data within a database or data warehouse, serving as a blueprint for all stakeholders.
Why the other options are wrong
- A. A disaster recovery plan outlines procedures for recovering from failures or disasters to restore data and services, not the internal design of the database.
- B. An operational runbook focuses on routine tasks, procedures, and troubleshooting steps for day-to-day operations, not the design of the database itself.
- C. A user manual is typically for end-users of an application, explaining how to use its features, not for technical stakeholders needing database schema details.
Database Design Document
A comprehensive document that describes the structure, relationships, and definitions of data within a database, serving as a blueprint for its implementation and maintenance.
- Includes schema diagrams, data dictionary, data models, and data lineage.
- Essential for communication between developers, analysts, and administrators.
- Ensures consistency and understanding of the database architecture.
Memory trick: The Design Document is the blueprint for the database house.
