Master the relational database architecture, declarative query formulation, and server-side procedural programming required to design, optimize, and maintain high-performance data storage systems. This course covers relational database design principles (normalization, entity-relationship modeling, and referential integrity), advanced SQL querying (complex joins, window functions, common table expressions, and set operations), procedural extensions (T-SQL, PL/SQL, stored procedures, triggers, views, and user-defined functions), index optimization strategies (B-Trees, covering indexes, and execution plan analysis), transaction management (ACID properties and isolation levels), and baseline NoSQL database paradigms (document and key-value stores). You will develop the technical capabilities needed to build robust database schemas, write secure and optimized queries resistant to SQL injection vulnerabilities, refactor slow-performing queries and optimize storage engine configurations, implement robust data backup, replication, and migration workflows, automate administrative maintenance routines, and ensure data integrity, security, and high availability across enterprise application backends.
