It is said that a DBA (Database Administrator) is a “Jack-Of-All-Trades”.
Based on our discussion of the role of a DBA in class, can you comment on the above statement.
(Hint: Databases interact with almost every component of the IT infrastructure. You need to identify the different IT disciplines, tools which a DBA must be aware of, though not be an expert in each of them.)
A DBA working with MySQL should have a good understanding of the underlying platform it is running on. There are a lot of configuration options that require the DBA to know how to interact with the operating OS in a manner that a sys admin would. For instance, MySQL will perform better if the databases (or indivdual tables) are on different disks. MySQL may even perform differently depending upon the location that the databases are on the hard disk. That all comes down to HD seek times. So a MySQL DBA should also be a system administrator, of sorts.
