Steps to Become a Database Developer

Step 1: Earn a relevant IT qualification

Complete a bachelor’s degree in IT, computer science, or a related field at an Australian university.

Write SQL queries, design schemas, and manage data sets. Personal projects and open-source work help build a portfolio to show employers.

Step 3: Gain real work experience

Apply for entry-level roles, internships, or IT support jobs to gain work experience. Look for junior database developer or data analyst roles in the first year after study. Many employers value hands-on experience as much as formal study, so build practical skills early.

Step 4: Earn a database certification

Complete a recognised vendor certification to build your credentials. Well-regarded options include the Microsoft Certified: Azure Database Administrator Associate and the Oracle Database SQL Certified Associate. These certifications take about two to six months to prepare for and are valued by Australian employers. Check current details on the provider’s website before enrolling.

Apply for membership with the Australian Computer Society (ACS) or DAMA Australia. You get access to events, industry networks, and CPD resources. It shows employers you are committed to your field. Apply at acs.org.au or dama.org.au once you are working in a database role.
