What is a database mission-statement? What exactly is a database mission-statement?  My question was prompted after submitting an academic-assignment requiring a "mission-statement" for ERD-modeling.  I've yet to encounter this requirement out in the wild as a software engineer, and I presume a mission-statement is akin to a thesis-statement, but I remain unsure after my Google-search.  Any DBA professional example or guidance explaining the ideal "database mission-statement" would be appreciated- thanks!
I thought that Jeffrey Yao did a fantastic job answering this question here. I've edited it a little bit and sometimes include my own mission statement on my resume, but here's my "slightly" modified version of Jeffrey Yao. This is not specific to mariadb, but I don't think it has to be.


  "Mission: I am committed to providing a robust and secure database
  system for my customers and as such, I proactively maintain and
  monitor the database system to prevent any potential issues;

  capacity; quickly respond to support request(s) and persistently seek
  innovative ways to improve DBA work efficiency and quality."
