Overview:
Oracle DBA (Database Administrator) is a key person responsible for the installation, configuration, upgrade, administration, monitoring, and maintenance of databases in an organization. The main role includes the design and development of database strategies, system monitoring and improving the performance of the database and capacity and planning for future expansion requirements. They plan to coordinate and implement security measures to safeguard the database.
Training Objectives of DBA:
Oracle DBA provides the essential SQL skills that allow developers to execute the queries against single and multiple tables, manipulate data in tables and creating database objects. Students will also learn how to use the advanced features of SQL in order to execute the query and manipulate data within the database, use the dictionary views to retrieve metadata and create reports about their schema objects.
