The role of Database Administrators (DBAs) are constantly changing, and changing for the better. Database Administrators are responsible for running enterprise databases and of late, they are watching a tremendous shift in the roles and responsibilities that they manage. They are being given more strategic roles. Instead of ensuring availability and access, they need to now shift their focus on developing architecture, design, and scalability strategies to meet business objectives and needs.
Let us understand the new roles that a DBA is indulged in these days.
- Easier Management – The Database Administrators are no longer required to be active 24/7 with the introduction of Cloud. Cloud has made tasks, such as database access and management, a lot easier. This has increased the DBA’s work-life balance.
- Shift in Tasks – Database Administrators are now being held responsible for data modeling, data security and performance monitoring, instead of only keeping databases active and running. These tasks provide them an opportunity to understand the importance of data in the expansion and growth of business.
- Introduction of Automation – An increasing number of tasks for Database Administrators are now being automated. They are using automation to verify that their tasks ran successfully, that database backups were successful and to monitor disk space. In fact, DBAs are now keen on automating more upcoming tasks.
- Becoming Data Engineers – DBAs have now shifted their focus on the movement of data from one database to another, consumption, and management of data until it is distributed and used.
- Need proficiency in more technologies – DBAs are now required to broaden their scope of learning. They must understand the methods and operations of NoSQL systems, learn how to administer Hadoop cluster and must be able to store data without a schema, among other tasks.
- Role of an Adviser – DBAs are more involved in the entire development processes now. They are responsible for providing information on data infrastructure capability, cost of the required changes, performance impact and capacity planning.
- Analyzing Big data – Database Administrators have also become a part of operating big data strategies. With the introduction of new tools and technologies that can manage data infrastructure and processes, their role has become much wider across a variety of databases and technology frameworks.
Increased Growth Opportunities
As more and more organizations are moving to the cloud, the databases are being transitioned from an on-premises model into a more flexible cloud model. Also, many organizations which have already moved to the Cloud, still have their databases being managed by their Database Administrators. These factors provide fuel to the increasing growth and job opportunities for experienced as well as upcoming Database Administrators.
Steps to be taken to keep abreast of the latest developments
There are various certifications for Database Administrators offering the required skills such as JSON collection modeling, data modeling for sharded deployments, data encryption, and key management. Certifications from Oracle, NoSQL and Microsoft pave a great way to update and enhance your skills in Database Administration. One must also enroll in a training for the suitable certification course in order to understand and master the skills in an easier manner.
