Database Administration is good but in which domain career making is good?
As per my knowledge, database administration is very good field to choose as career path. Using this skills we can earn more knowledge as well as earn more money too. But important question is which RDBMS is good for career making in DBA?
In MySQL:
MySQL is available with GPL license and enterprise license. Most of websites are using MySQL as backend because those are using very tiny database and not large. Enterprise MySQL is good but I don't think you can earn more in MySQL DBA field.
In IBM DB2:
IBM DB2 is very good RDBMS because it supports to various kind of operating systems and available with different kind of licenses. It also supports large databases. Unfortunately, I haven't seen DB2's popularity and demand.
In MS SQL:
Microsoft SQL Server has good popularity and more demand. Database administration tasks are very easy because of GUI tools available. Limitation is platform dependency. It is not available on Unix and Linux platform and available on only Microsoft Windows platform only. You can earn more but with limited in knowledge.
In Oracle:
Oracle is most popular and has large demand. It supports various operating systems. It supports large databases and available with different kind of licenses. Oracle ERP is also available and another options are also available for future upgrade. You can earn more and with expansion of knowledge too.
Hence, we can say that there are number of oppertunities available with Oracle if you select database administration career. There are number of online Oracle courses also available with quick upgrade and refreshes.
