I want to take online classes on database/ ETL testing. Also i look forward to teach Mathematics/Science for class X-XII

Hi, I'm an automation test engineer and a certified s/w test engineer (CSTE - QAI). I work with databases at a beginner level but I'm planning to master working with databases. I'm interested in taking a certification exam as-well. I am not interested in making a career switch but want to add it to my skill set. Considering my background, what training/certification should I go for? Please also suggest some beginner level certifications that would be helpful for me to add to my skill set.
