15 QuestionsBeginnerHigh Priority ~10 min read

Tables are where MySQL actually stores your application data. A table is made up of columns that describe the type of information being stored and rows that contain individual records.

Creating a good table means choosing the right columns, data types, constraints, and keys. These decisions affect how easy the database is to query, how consistent the data remains, and how well the application performs as it grows.
