Welcome to database development using one of the most powerful database management systems – Structured Query Language (SQL). Many database management system (DBMS) tools run on a variety of hardware architecture. The differences among the tools can be great, but all serious products have one main thing in common: they provision SQL data access and manipulation. If you know SQL, you can build relational databases and get useful information from them. This series of courses will guide you through each step of the SQL architecture, how to create effective SQL databases, and how to effectively manage them. You will gain knowledge of database theory, concepts, and design so that you're equipped to create an effective database.
