Oracle Database -SQL Certified Expert Central

Course details

Oracle Database SQL Certified Experts demonstrate the complete set of skills required for working with the powerful SQL programming language and have mastered the keyconcepts of a relational database. SQL Experts understand how to use the advanced features of SQL in order to query and manipulate data within the database, controlprivileges at the object and system level, and use advanced querying and reporting techniques. They are able to manipulate large data sets and understand storing and retrieving dates according to different time zones. They are also knowledgeable about the concepts of controlling access and privileges for schema objects.
