Some work I have done on a personal database running off my own computer. It consists of clients I use, the games that each client offers, my user name and passwords. In this example I show that I understand inner joins. I have primarily used inner joins when working with data base work. All of my work has been in SQL using MySQLWorkbench running off a designated server or my own server.
Some other work I have done for a quiz that I have created that uses a database for questions, answers and hints to the questions. The second image is am inner join between the answers and the questions linked to each other. The third image is an inner join of the answers linked to the question hints. This is also done using SQL and MySQLWorkbench.
Lastly is some documentation work I have done using ER Diagrams on how a database will be set up and what needs to be linked to each specific table. I used Microsoft Visio to complete my ER Diagram work.
