Oh, a pop quiz to kick things off! Relational databases have been around for almost 50 years? That's pretty impressive longevity for a technology.
It's good to get an introduction from someone working in the field. Jamil sounds like he'll break down the characteristics and benefits clearly, which is exactly what I need to understand if this is the right choice for a project.
Mapping out data points and relationships using tables sounds like a really intuitive way to organize information. Focusing on entities and nouns as the basis for tables makes a lot of sense for prototyping.

Relational databases structure data into tables, representing entities like "books" [0:47]. Each table has columns for attributes such as "name" and "author" [1:11], and critically, a unique ID for each row [1:34] to identify individual records. Data retrieval is primarily done using Structured Query Language (SQL) [1:58]. The power of relational databases shines when connecting different entities, like books and authors, through relationships. This is achieved by using a "foreign key" in one table (e.g., author ID in the books table) that references the primary key in another table [2:45-3:09].
