You already have an IT staff. Microsoft’s SQL Server can be installed with a few clicks. So why would you need a database administrator (DBA)?
DBAs save the day during disaster scenarios
No one knows database systems like DBAs. When your system crashes, your systems admin may be able to figure out the issue, but DBAs have the academic background and experience to resolve it. The help systems quickly recover by preparing for disaster scenarios. They have data security in mind every step of the way. They have experience on the best ways to perform backups and restores.
Having a specialist who knows how to troubleshoot and recover your intricate database saves your business time and prevents further damage from guess work. On a worst-case scenario where DBAs encounter a problem they haven’t fixed before, they have the connections and resources that other IT specialists do not have.
DBAs prevent the disaster scenario
DBAs exhibit somewhat of an obsession with data — as they should. It is their job (and it is ingrained in them, due to past experiences) to make sure that the set-up of a system is done properly. They know better how to configure a system to suit it to your business’ needs. SQL Server support provider DBA Services warns against improper SQL Server configuration and maintenance as this will degrade the system’s performance over time.
DBAs prevent system problems by striving to do everything right the first time. They continue to prevent problems by monitoring the system and conducting performance tuning.
Your current IT team may be great, but each member has specialisations. You can’t think of your IT department as the ‘computer guys’ who should know everything about computer systems. Even DBAs have specialisitions. You can’t expect the development DBA and application DBA to have the same expertise.
The bottom line: If you have a database system and you need it to run well, you need a DBA.
