In a database:

  • Table is a structure that stores data in the form of rows and columns, similar to an Excel sheet. It represents a set of related data.

  • Column is a single field in a table that defines the data type and contains values of one type for all records. For example, the "Name" column stores the names of all users.

  • Row (record) is a single entry in a table, consisting of values for all columns. For example, one row may contain data for a single user: name, age, email, etc.

Example:

ID Name Age
1 Anna 25

Here, the table is the entire structure, the column is "Name", and the row is the record with ID=1.
