The main technical difference between a spreadsheet and a database comes down to the way they store data. In a spreadsheet, data is stored in a cell, and can be formatted, edited, and manipulated within that cell. In a database, cells contain records that come from external tables.

<h3>What is the difference between a spreadsheet and a relational database?</h3>

Databases use tables as a means of storing and retrieving information.

Tables are organized as columns (fields) and rows (records).

This tabular structure is similar to spreadsheets, but unlike a spreadsheet, most databases are relational, meaning that data between tables can be linked and cross-referenced.

In a relational database, data in a table can be related according to common keys or concepts.

Relationships are a logical connection between different tables and are established based on the interaction among these tables.

Well-defined relationships (rules) between database tables can be established to enforce restrictions on the data.

Tables communicate and share information, which facilitates data searchability, organization, and reporting.

Typically in a spreadsheet, the information is formatted. Therefore, adding new data can be tedious.

Since database tables store the raw data without formatting, data entry is easier.
