3. SQL
Master SQL (Structured Query Language) for querying and managing data in databases.
4. Data Modeling
Understand data modeling techniques to design efficient database schemas.
5. Backup and Recovery
Learn about database backup, recovery, and disaster recovery procedures.
6. Performance Tuning
Gain skills in optimizing database performance through indexing, query optimization, etc.
6. Gain Experience
Start with entry-level roles like database developer or data analyst to gain hands-on experience with databases.
Progress to roles that involve more database administration responsibilities as you gain experience.
7. Certification
Consider obtaining certifications from database vendors (e.g., Oracle Certified Professional, Microsoft Certified Solutions Expert) to validate your skills and knowledge.
