Overview / Oracle




This course gives intense understanding of SQL and PL/SQL and their tuning capabilities which can enhance the performance. It discusses the goals for tuning and provides tuning suggestions. This presents the operation of SQL Tuning Advisor utility and portrays the SQL Tuning sets that include execution statistics and execution context. It depicts the idea of automatic SQL tuning with SQL Profiles and includes the types of tuning analysis.

This course provides an overview of data access methods using indexes and clusters that can improve the performance along with the usage of SQL Tuning Information Views. It describes the use of Dynamic SQL with PL/SQL to make programs more flexible by building and processing SQL statements at run time. It also delivers the idea of data abstraction which lets us to work with the properties of data, how to manage the object type and how to deal with the language elements. It supplies information about the standalone wrap utility to obfuscate the PL/SQL source code.
