Oracle Database 11g: Analytic SQL for Data Warehousing - LVC

: 1 Day

What you will learnIn this course students use Analytic SQL to aggregate, analyze and report, and model data. Students learn to interpretthe concept of a hierarchical query, create a tree-structured report, format hierarchical data, and exclude branches fromthe tree structure. Students also learn to use regular expressions and subexpressions to search for, match, and replacestrings. Before attending this course, students should be familiar with relational database concepts, data warehouse theory andimplementation, Oracle server concepts including application and server tuning, and the operating system environmenton which the Oracle Database Server is running. Students use Oracle SQL Developer to develop these program units.SQL*Plus and JDeveloper are introduced as optional tools. This course is intended for data warehouse builders and implementers, database administrators, system administrators,and database application developers who design, maintain, and use data warehouses. Learn to:

Use Analytic SQL to aggregation, Analyze and Reporting, and Model Data Group and aggregate data using the ROLLUP and CUBE operators Analyze and report data using Ranking, LAG/LEAD, and FIRST/LAST functions Use the MODEL clause to create a multidimensional array from query results Interpret the concept of a hierarchical query, create a tree-structured report, format hierarchical data, and excludebranches from the tree structure Use regular expressions to search for, match, and replace strings
