The key challenge that DBAs are facing today is the conversion to an application-centric model from the traditional IT infrastructure model. This means, the database administrators have to keep updating themselves so that they can work with different structures of data like structured, semi-structured & unstructured, and various varieties of databases like relational, object-oriented, object-relational, non-relational, cloud, etc, and maintain data in an organized format. So, it's a challenge for the DBAs to handle large amounts of changing data with the latest technologies while maintaining an application-specific mindset. They can achieve this by continuously monitoring the application performance keeping database as a priority.
