The gathering, storing, organising, and processing of data is the responsibility of a database administrator, often known as a DBA. One of the top 10 technology jobs in the world is this position. DBAs regularly collaborate with other data analysts to ensure that the correct people have access to the information they require. They are, in reality, the data gatekeepers of a corporation. Installing server software, setting database servers, and backing up data to prevent accidental loss or distortion are just a few of their tasks.
The primary function of a DBA is to ensure the integrity of the data. If the data is wrong or corrupted, a fast and accessible database is meaningless. “It’s been claimed that the database administrator has three basic tasks,” Bob Watkins summarised a DBA’s responsibilities. Protect the data, safeguard the data, and protect the data, in decreasing order of priority.”
Some database administrators specialise in one of three areas: system database administrators, development database administrators, or application database administrators. System database administrators are primarily concerned with the database’s physical and technological components, which include updates and problem fixes. A development DBA is responsible for the creation of data model designs, including SQL code and tuning. Application database administrators specialise in certain applications and are capable of writing and debugging code.
A good understanding of Database Management Systems and database languages is required of a database administrator. The structured query language (SQL) is the most widely used database language today, and it is utilised by a variety of companies. A DBA should also be conversant with PowerShell (for Windows) and Bash (for Linux), both of which are widely used.
An internship – especially if it is a paid job – could be a good way to break into this area. By completing tasks that are conducted on a daily basis, applicants are prepared for the obstacles that a DBA tackles. This type of training can be quite beneficial, as it allows you to exchange theoretical knowledge for hands-on experience while also raising your chances of being hired by the internship provider.
Many companies, predictably, hire people who are certified in the systems and languages they utilise.
Job candidates should be knowledgeable with at least one of the following database management systems: Sybase, Microsoft SQL Server, MySQL, Oracle 11g, and IBM DB2. Even better if you can find out what software a company uses before a job interview.
Managers, researchers, and other employees collaborate closely with a database administrator. The DBA’s primary responsibility is to monitor and maintain a high degree of system performance. Database administrators are in charge of performing frequent system backups to ensure that no data is lost in the event of a power loss or other disaster. They also seek to guarantee that the data collected is accurate, dependable, and accessible at all times.
Administration and social skills
Soft skills are becoming more important in the employment process, and database administrators are no exception. Soft skills are key components in a DBA’s problem-solving efficacy, in addition to educational qualifications, technical expertise, and industry-supported certifications.
Database administrators must work in teams, which necessitates effective communication. They must also be able to lead and work as part of a team. The DBA must operate independently, be detail-oriented, and communicate effectively with other members of the team.
Administrators of the Cloud and Databases
Database administrators’ duties and responsibilities are changing dramatically as a result of cloud computing. DBAs who work in the cloud don’t have to be tied to their databases. With the move to the cloud, a DBA’s responsibilities are gradually evolving away from hands-on tasks and into proactive projects that improve efficiency. Database administrators can concentrate on creating solutions and innovations that benefit IT teams and end users. Oracle’s Cloud Business Group’s Senior Vice President, Steve Daheb, said:
“The average DBA manages 50 databases and spends 90% of their time maintaining them. They’re now focusing on higher-value jobs, such as business analytics, rather than tuning and provisioning. It is viewed as an opportunity by them. It’s all done in the cloud. The cloud, for example, is an enabler for IoT because, after all, where would you keep all that data coming in?”
Database administrators are responsible for capacity planning. Capacity planning is the process of estimating how many resources will be required – and how many will be available – in the future. Computer hardware, software, storage, and network infrastructure are examples of these resources. Fortunately, infrastructure-as-a-service (IaaS) planning is very similar to on-premise planning. The main difference in planning is the extra flexibility that the cloud provides. This flexibility enables DBAs to plan for the business’s urgent needs rather than three to four years ahead of time. DBAs can also take advantage of the cloud’s flexibility to scale up or down fast to meet a client’s needs.
Responding to changes in a cloud’s offers with the purpose of receiving the best deals is part of good capacity planning. A cloud service provider, for example, might introduce a new type of virtual machine or a new storage solution that is better suited to an organization’s workloads. The DBA must be mindful of the changing demands of the business and the technologies available in the various clouds.
