Master database design by modeling entities, attributes, and relations with an ER diagram, define keys, domains, and cardinalities, and optimize relational MySQL schemas.

Install and launch MySQL Workbench to model, design, and administer your database; connect as a non-root user, build diagrams with tables and relationships, and use the visual design surface.

Understand how database tables use primary keys and foreign keys to uniquely identify rows and relate tables, with constraints and third normal form for OLTP design.

Normalize a school database by separating student and course data into distinct tables and using a student_course link table to enforce data consistency and reduce redundancy.

Compare fixed-length char and variable-length varchar storage in MySQL, including text types, and weigh storage efficiency, overhead, and performance for strings, plus date, datetime, time, timestamp, and year types.

Design a contacts table using varchar and fixed-length types with sizes like 15, 45, and 50. Focus on normalization, photo path storage, and forward engineering with MySQL Workbench.

Explore how MySQL implements acid principles through implicit and explicit transactions, savepoints, and commit or rollback to ensure atomicity, consistency, isolation, and durability.

Explore row-level and table-level locks, deadlocks, and isolation levels—serializable, repeatable read, read committed, read and committed—plus phantom, non-repeatable, and dirty reads, all backed by binary logging.

Explore MySQL isolation levels and locking, compare read uncommitted, read committed, repeatable read, and serializable; see how global settings and transactions affect data consistency and concurrency.
