A database is more than just a place to store information, it is the heartbeat of an application.
Efficient data management, fast retrieval, and reliable concurrency control are essential building blocks of modern software.
In this section, we’ll explore a wide range of database concepts, from relational systems to NoSQL, while diving into core principles like transactions, indexing, and query optimization.
By going beyond basic usage and understanding how data is stored, retrieved, and maintained, you’ll gain the foundation to design systems that are both stable and powerful.
