Using appropriate data types reduces storage and improves performance. For example, storing a boolean as a CHAR(1) 'T'/'F' is less efficient than using BIT or BOOLEAN. For timestamps, use TIMESTAMP (4 bytes) instead of DATETIME (8 bytes) where possible. For integers, choose INT (4 bytes) vs BIGINT (8 bytes) based on range needs. For timestamps, use TIMESTAMP (4 bytes) instead of

Detailed accounts of how researchers discovered vulnerabilities in programs like Proton, AWS, or government websites.

From the moment you check your email to the instant you stream a movie, a database is working behind the scenes. The humble has evolved from flat files to distributed, self-healing, cloud-native systems. Understanding database fundamentals—whether you’re a developer, a business owner, or a student—gives you a powerful lens into how our digital world operates.
