What are the potential pitfalls of storing category information in a database with numerical identifiers?

Storing category information in a database with numerical identifiers can lead to confusion and errors when trying to interpret the data. To solve this issue, it is recommended to use descriptive names or labels for categories instead of numerical identifiers. This will make the data more readable and easier to work with.

// Instead of storing category information with numerical identifiers
// Use descriptive names or labels for categories

// Incorrect way
$category_id = 1;
$category_name = "Electronics";

// Correct way
$category_name = "Electronics";
