Their main goal is to ensure the availability and consistent performance of various corporate applications. SQL Server these days is a complex software that goes beyond Database Administration. There are many features in SQL Server including SSRS (SQL Server Reporting Services),
SSIS (SQL Server Integration Services), etc. You may not have a chance to learn
or use all of these features during your career. This might be challenging (to try
to learn all of them), but a good thing about this is that there is always something
new to learn and try.
In addition, DBAs work with application developers to ensure accurate and efficient application design for database access. At times, DBAs may be asked to modify or write application code to help development projects. As the central point of contact for information about the company’s database management systems, DBAs must keep up https://g-markets.net/software-development/java-7-what-s-in-it-for-developers/ to date on the latest versions and capabilities of each DBMS. They also must educate and inform application developers and other users about how to use the DBMS and its facilities. The DBA also must establish policies and procedures pertaining to the management, security, maintenance and use of the database management system.

Some small companies that only use externally hosted applications or don’t
have in-house IT may not have a DBA. Very often, when a company grows, it starts
implementing new applications with databases. Sometimes a person who is looking
after IT infrastructure (usually a sysadmin, sometimes a developer) may have some
knowledge about database administration and he/she provides basic database support. Yet, another type of database administrator is the Performance Database Administrator or Tuning Database Administrator. This administrator specializes in optimizing and improving the performance of various databases. Simply put, a database’s internal structure consists of data stored within tables.
Just as the term ‘doctor’ can refer to a wide range of specializations, there is also a wide range of sub-specializations for the database administrator role. The DBA we described previously is the most common—one who works in-house or on contract for an organization to keep their internal databases chugging along optimally. A senior DBA has spent a couple/few years working as a junior DBA. They’re used to doing the common tasks like configuring backups, troubleshooting outages, managing security, and responding to end user requests. That’s not to say they don’t still do tasks for the first time – they often do, and they rely on Google to help them figure things out.
What training prepares you to get the first DBA job?
Because databases are at the center of most modern application development projects, the DBA participates in database integration and use in a variety of IT projects. This exposure to many different technologies and experiences can make the DBA a valuable IT technician not just for database-related issues, but for other technologies as well. Database administration is a vital component of the IT environment for any organization that relies on one or more database management systems. SQL Server Database Administrators areresponsible for the implementation, configuration, maintenance, and performance of critical SQL Server RDBMS systems.

- Database Administrators are professionals who ensure that all databases, including those for financial or customer information, stay up-to-date with policies and procedures in place to protect against data loss.

But at least half the time, they’re doing things they’ve already done before, and rather than Googling the concepts, they’re Googling the most efficient way to do it at scale, like automating it with PowerShell. This gets a little confusing because some businesses just slap the term DBA on everything. “If they’re working in the database, they’re database administrators,” hahaha. A transaction log file can easily grow in size if it’s not truncated. Truncation helps free up space within the log file by removing backed-up transactions. Some DBAs assume that taking a full database backup helps truncate the transaction log.

Is it easy to become a DBA?
Database administrators need at least a bachelor's degree in information science or computer science for most entry-level positions. Depending on the size and complexity of their company or governing body, these professionals may need a master's degree in database administration or information technology.
They may get involved in application tuning when operating system parameters or complex DBMS parameters need to be altered. Without the DBA’s oversight, application and system outages, downtime, and slowdowns will inevitably occur. These kinds of problems result in business outages that can negatively affect revenue, customer experiences and business reputation.
