Databases store, organize, collect, and retrieve data, and, given the amount of data some databases store, how they’re built can seem disjointed and confusing. To overcome these obstacles and make databases useful, computer scientists developed complex algorithms and database designs to create efficient and accessible databases. Relational databases are an example of this type of solution. They store data in tables that are related by different unique keys so that relevant data is stored together, but different data combinations can still be retrieved using the unique identifying keys.
Explore these topics by creating a simple query to retrieve data, normalize a sample database, and design an entity relationship diagram (ERD).
