Oracle DBA

Course Overview:

Oracle is an object-relational Database Management System created by Oracle. It includes various concepts like Oracle DBA Architecture, database structures, memory and process architecture, security, schema objects, data backup, and recovery. DBA’s are responsible for the design, implementation, support, and maintenance of computerized databases in today’s organizations. Here we can learn how to operate the stored data and return meaningful results to analyze the data stored.
