Beginner Documents First Day Learning SQL, From Databases to CRUD Operations

A first-time learner shared their introductory experience with SQL, noting it differs significantly from spreadsheet tools like Excel. They explored the two main types of databases: relational databases, which store data in rows and columns (e.g., MySQL, PostgreSQL), and NoSQL databases, which store data in non-tabular formats such as JSON or documents. The learner also studied basic CRUD operations using standard SQL commands. During practice, they encountered two syntax errors — a missing comma in a CREATE TABLE statement and absent quotation marks in an INSERT INTO command — both of which they resolved independently. The session provided a foundational understanding of SQL structure and common beginner pitfalls.
