Database Design and Optimization

A career in data engineering requires not only handling data but also an understanding of databases, the architectural framework that keeps everything together. Consider attempting to construct a skyscraper without a solid foundation. Eventually, that structure is going to collapse. Any data pipeline can benefit from this as well. No matter how skilled you are with data manipulation and coding, your data pipelines can become unreliable, expensive, and inefficient if you don’t have a firm grasp of database design and optimization.

In-depth knowledge of the fundamentals of database design and data modeling will be covered in this chapter, empowering you to create databases that are not only reliable but also scalable and effective. Our aim is to prepare you to become an expert in these vital aspects of data engineering, starting from the fundamentals of tables and relations and progressing to the complexities of indexing and normalization.
