Relational database basics (tables, rows, columns, primary keys). A database is an organized collection of data designed to efficiently store, retrieve, and manage information.

In a relational database, data is organized into tables: - Columns (fields): Attributes like "Name", "Price", "Date" - Rows (records): Single entries with values for each column - Primary key: Special column that uniquely identifies each row (CustomerID, OrderID). No duplicates. - Foreign key: Column referencing another table's primary key, establishing relationships.
