Database Administrator

A Data Administrator, often referred to as a Database Administrator (DBA), is responsible for managing, securing, and maintaining an organisation’s data infrastructure. This includes the tasks of designing database systems, keep them running smoothly, and making sure they are safe and reliable.

In an online shopping website for example, a Data Administrator manages the database that tracks inventory. This means making sure that when you search for an item, the system quickly finds it and updates the stock levels once you make a purchase. If there is a sale or a big event, they ensure the system can handle a surge in users without crashing. 

When it comes to banking apps, a Data Administrator ensures that all transactions are recorded accurately and securely. So, you can trust that your account balance is correct and that your financial data is protected from hackers. 

The core responsibilities of a Data Administrator typically include:

• Database Installation and Configuration
• Performance Monitoring and Tuning
• Backup and Recovery
• Security Management
• Data Migration and Patching
• Capacity Planning
• Troubleshooting
• Compliance
• Database Installation and Configuration 

Setting up a new database is akin to constructing a new building. Data Administrators meticulously install and configure databases to ensure they function at peak performance.

For example, when a retail company expands and needs a new inventory management system, the Data Administrator will set up the database, configure it to handle thousands of transactions per minute, and ensure it integrates seamlessly with existing systems.

Data Administration is a diverse field with various specialisations, each catering to different organisational needs and technological environments.
