Some good information and links summarized for Oracle Certification Path – by Rayudu Addagarla
Irrespective of any technology you major in, A good database background is very useful and a must to succeed in the career.
Taking the case of various BPM Suites in market a good number of them still depend on application developers and bring legacy or relational or corporate data into the business forms/dashboards/BI tools.
Some Suites claim that there is zero foot print and no knowledge of SQL is necessary, they actually wrap the sql stuff with smart services to do this. But in case you are starter into technology, It is very important to understand Database and Data Structures.
Might be good to take a basic Data Structures/Database Course.
Here I give details keeping Oracle in perspective. But there are exams for Microsoft SQL Server as well if you are interested which a link is provided as well at the end.
I am here trying to give all the information at one place as most of the time the same information needs searching in Google and spend a lot of time.
Though I am not an oracle certified myself, I have 15yrs of IT experience and been using Oracle since 1996 and developing Web and Windows/Java GUI’s using Oracle as backend.
