Database Design: designing the structure of databases, including defining tables, fields, relationships, and data integrity constraints to ensure efficient data storage and retrieval.
Database Installation and Configuration: installation and configuration of database management systems (DBMS) such as MySQL, Oracle, SQL Server, or PostgreSQL This includes setting up parameters, security settings, and optimizing performance.
Data security: establishing and enforcing security policies to protect the organization's data This involves setting user permissions, implementing encryption, and implementing access controls to prevent unauthorized access or data breaches.
Data Backup and Recovery: create and maintain backup and recovery strategies to ensure data can be restored in case of accidental data loss, system failures, or disasters.
Performance Tuning: monitor database performance, identify bottlenecks, and optimize queries, indexing, and server resources to ensure the database runs efficiently and meets performance requirements.
Data migration handles data movement between different database systems or versions. This may involve data import and export, transformation, and ensuring data integrity during the process.
Database Maintenance: Routine maintenance tasks, such as updating software, applying patches, and ensuring data consistency
Capacity Planning: assessment of the database's capacity needs, planning for scaling, and ensuring that the infrastructure can handle data growth over time.
Data Modeling: create and maintain data models to represent the organization's data structure, relationships, and data flow, helping to ensure that the database design aligns with business requirements.
Disaster Recovery Planning: develop and test disaster recovery plans to minimize downtime and data loss in the event of a catastrophic failure or disaster.
Database Documentation: Maintaining comprehensive documentation on database schemas, configurations, and procedures is essential for effective management and knowledge transfer.
Database Security Auditing: Regularly auditing the database for vulnerabilities, access controls, and compliance with data protection regulations and industry standards
Troubleshooting: diagnose and resolve database-related problems, whether they are related to performance, data corruption, or configuration.
Collaboration: DBAs often collaborate with developers, system administrators, and other IT professionals to ensure that the database systems meet the needs of the organization.
Compliance: ensuring that the database and data management practices adhere to relevant industry regulations and compliance standards, such as GDPR or HIPAA.
Monitoring and Alerting: Using monitoring tools to track database performance, health, and availability and setting up alerts to be notified of any issues in real-time
