A company stores its operational data in a MySQL 8.0 server. You have been asked to reverse-engineer the existing schema into an entity-relationship (EER) diagram, make minor table changes with a visual editor, and run ad-hoc SQL queries in the same workspace. Which tool from the CompTIA Data+ list is specifically designed for this end-to-end database modeling and administration task?
MySQL Workbench is purpose-built for designing and administering MySQL databases. It can reverse-engineer an existing schema into an EER diagram, let you edit tables and relationships in a graphical canvas, and includes an integrated SQL editor for running queries-all within one interface. RStudio is an IDE for R/Python code, not a database design tool. Power BI Desktop focuses on building dashboards and does not create or modify database schemas. The pandas library supplies data-wrangling functions inside Python but offers no visual modeling or direct database administration features.
