LESSON 7 — The Habits That Make You Employable (Your DBA Professional Standards)

Habit 1: Don’t guess

If you didn’t measure it, you don’t know it.

Habit 2: Don’t change multiple things at once

One change at a time keeps the cause-and-effect clear.

Habit 3: Always keep proof

Screenshots, query output, notes, or logs.

Habit 4: Always write a short summary

Even 5 lines is enough:

• what happened

• what you found

• what you changed

• what improved

• what you will prevent next

Habit 5: Build reusable assets

A job-ready DBA owns:

• checklists

• triage scripts

• backup/restore runbooks

• change templates

These assets become your portfolio.
