Database Management SystemA database is an organised collection of data. The data is typically organized to model aspects of reality in a way that supports processes requiring information, such as modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.

Types of Databases

● MongoDB, Amazon RedShift, Riak

● VoltDB, Clustrix, NuoDB

Why is being a DBA cool!

● Niche field

● 50k to 150k SGD per year

day will never come)● Performance Tuning (Undefined science!)● Upgrade, Patching, Migration● Database engineering** (My personal favourite!)

After Seagate….

● Joined a SME company as an Oracle database “Consultant” in Feb 2014

● High volume traffic● Low latency● Database security● And… I’m the guy that manages the

database :)

look good in-front of HIS boss● Be happy when someone bother to criticize you● Bring solutions, not problems to the table

if [age < 30]; then echo “experience > $” fi

● No commitments when you are young● Build a strong foundation first● A job with better exposure is MUCH better

than a job with better $$!!!● If you can, create your own startup!
