Please refrain from making unconstructive edits to Wikipedia, as you did at Software engineering. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. Meters (talk) 17:06, 1 May 2018 (UTC)

Please stop your disruptive editing. If you continue to vandalize Wikipedia, as you did at Relational database, you may be blocked from editing.  General Ization Talk  17:47, 1 May 2018 (UTC)
