Hello, I'm Mojo Hand. An edit you recently made to Edgar F. Codd seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Mojo Hand (talk) 13:35, 6 September 2021 (UTC)
