They also optimize database performance, troubleshoot issues, and develop backup and recovery strategies.
Database engineers use a variety of tools and technologies, such as SQL (Structured Query Language), NoSQL databases, cloud-based databases, and data warehousing. They also need to stay up to date with the latest trends and developments in database technology.
To become a database engineer, one typically needs a degree in computer science or a related field, as well as experience with database management systems and programming languages. They also need strong analytical and problem-solving skills, attention to detail, and the ability to work collaboratively with other members of a development team.
