LB115 Database Fundamentals
MET LB115 is a self-paced online laboratory that builds practical, graduate-ready fluency in database fundamentals. Through short modules, you will learn what databases provide for applications and organizations; conceptual and physical schemas with ER diagrams; core SQL to retrieve and modify data; and the essentials of performance, indexing, and transactions. The focus is on understanding and applying standard patterns rather than installing or administering specific software, so no database management system is required. Each unit culminates in an open-book, timed test that checks deeper understanding by asking you to compare options, identify correct patterns, and apply fundamentals to realistic scenarios.
