Hello, I'm Djm-leighpark. I noticed that you added or changed content in an article, Optimistic concurrency control, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Actually I haven't removed it but marked it as citation needed. If you have a source for the claim that would be great otherwise it will likely be removed at some point. Thahkyou.
