Database management is fundamental to modern applications. Understanding how to store, retrieve, and manipulate data efficiently is essential for developers and data professionals.
Relational databases organize data in tables with rows and columns. SQL (Structured Query Language) allows you to query and manipulate this data. Learning SQL is valuable even if you work with other database types.
Database normalization reduces redundancy and improves data integrity. By organizing data into related tables and establishing relationships between them, you create a more efficient and maintainable database structure.
