The Ultimate Guide to Becoming a Database Administrator
The digital revolution is underway as more businesses and enterprises adopt technologies such as Artificial Intelligence and Machine Learning (ML). Every day, 2.5 quintillion bytes worth of data is created. This data is then stored, analysed, and used to generate insights. More than 90% of all human data to date has been collected in the past two years.
All of this information is put into what data scientists refer to as a database. All this data is useless if it is not analysed and understood properly. As organisations invest more in data collection, they are looking for experts who can extract insights from the data and add value to their businesses. This is where Database Administrator skills are needed.
What is a Database Administrator?
Database administration includes everything needed to manage a database and ensure that data and insights are always available. Database administrators (DBAs), manage and back up the data and make sure it is available to businesses through their IT systems. This is a crucial job role for every organisation, and the demand for DBAs will continue to grow as technology advances.
Database Administrators have the following key responsibilities:
Upgrade and installation of database servers/application tools
Modifying the database structure using information from the application developers.
Assuring compliance with the database vendor agreement. This includes checking the number and renewing licenses on-time.
System security is ensured by carefully allocating user permissions.
Prepare a backup plan and recovery plan for the database. Also, ensure that these backups are accessible.
The DBA has one of the most important tasks: monitoring and optimizing the performance of the database with either manual or automatic tools.
Migration of database instances to new hardware and software versions from on-premise databases to cloud-based ones

Types of database administrators
Database administration students have many options. In-house DBAs are the most common category. They work on organisations’ payrolls.
Another type of DBA is either the Performance Database Administrator (or Tuning Database Administrator). This DBA optimizes and improves the performance of different databases. A database is composed of tables that contain data. This data is optimized and indexed to make it easy to access when needed.
Another sub-specialization is Application Database Administrator. This role is responsible for integrating databases into the applications that need them. This requires knowledge of SQL (Structure) query language.
