Must-know advanced database concepts

After going over the basics of databases, it’s time to delve into more complicated subjects that are essential tools in the toolbox of a data engineer. We’ll summarize various advanced concepts, including triggers, ACID characteristics, and constraints. To guarantee data integrity, consistency, and responsiveness in a database system, each aspect is crucial. Understanding them will improve your conceptual knowledge and your capacity to create and maintain sophisticated database systems.

Remember that this part is not intended to teach you how to do these things from scratch but rather to provide you with a brief overview and prepare you for the kinds of questions and subjects frequently used in interviews for data engineering jobs. Let’s clarify things and increase your knowledge of databases.

Constraints
