What is a Database Administrator?

Most people will have come across a SQL Server DBA in their IT careers.  They’re the guys who are notoriously strict, who won’t allow anyone access to their data or to write code against their precious servers, but what are they actually there for and what do they do?

The general answer is that their role is to keep databases accessible, control access, and maybe perform the odd backup and restore.  If that were the case then they would have a very short work day indeed.

The role of a DBA is more than a simple gatekeeper.  Data is the underpinning life blood of nearly all companies these days and, with that in mind, the DBA’s life involves constantly monitoring, tweaking, tuning, and manipulating databases and servers to ensure that all data is in pristine condition, can be obtained and manipulated with ease and efficiency, and that server resources are utilised to their full despite tight budgetary requirements.

A good DBA will, with the correct SQL Server Training, be able to ensure their servers are highly available, suffering absolute minimal downtime in a crisis, can support developer activity, and service customer and client’s data needs with little effort, all whilst keeping the data as secure as possible by controlling encryption and access rights.  All this in addition to ensuring developers have suitable test and UAT environments to code against.

The best DBAs will likely have done further SQL training Courses and also have a firm coding ability, being a gatekeeper for the code being released on their servers.  They should have the ability to look for poorly performing code in a database, understand its method of execution, how the database engine is processing the data, and suggest coding or architectural solutions for developers to consider.

All in all, the next time you hear about a DBA being simply the “grumpy guy controlling access”, you’ll maybe have a better understanding that he’s got a lot more on his plate than simply worrying about who’s accessing his servers and, instead, you’ll consider attending a SQL Server Training Course yourself in order to improve your code and take some weight off his stressed out shoulders.
