I invest a lot of free time in preparation for "Oracle Database 11g Administrator Certified Associate" and "SQL Certified Expert".
Those exams really tough, but I am willing to learn.
I wish to use the gained know how for at least 35 years!
I attended an Open Source conference and those presenters said that NoSQL is the future.
They said nobody will use proprietary RDBMS in about 10 years.
That's really bad news. Will my know how be useless in 10 years?
I wish to use the gained know how for at least 35 years!You are in the wrong industry. In the IT field, 35 years is an eternity. Going back 35 years from today would be 1977. The PC doesn't exist. It's a mainframe world.
I attended an Open Source conference and those presenters said that NoSQL is the future.I went to a Honda dealership a few weeks ago. They said Toyotas are passe and Hondas are the future...
They said nobody will use proprietary RDBMS in about 10 years.Very Very Very unlikely. Companies that use Oracle tend to have enterprise-class databases. They have a huge investment in technology and personnel and time in their current system. You don't just decide one day to throw all of that away and change to something completely different. I can't really say what reasons your lecturers gave to suggest that they would because I wasn't there. However, when you have millions of dollars invested in a system, there has to be a compelling reason to change. Heck -- there are still businesses using systems developed in COBOL of all things because of legacy investment in it.
That's really bad news. Will my know how be useless in 10 years?Maybe. If the Mayans put out an updated calendar that says the world will end in 2023.
