Agenda Relational databases Database organization What’s been done How to:

- View / lookup data

- Access phpMyAdmin

- Enter new data into the database

It’s a database system in which any database file can be a component of more than one of the database's tables.

What is a relational database?

Example

Magnet CORE ID Picture

1 12423

2 456

3 23463

This is one table of a database…

Magnet-Magnet- 1 1

CORE ID-CORE ID- 12423 12423

This page utilizes another table in the SAME database…

Hence, the word RELATIONAL…

Magnet-Magnet- 2 2

CORE ID- 456CORE ID- 456

Yet another…

Magnet-Magnet- 3 3

CORE ID- 23463CORE ID- 23463

And another…
