This document contains examples of database normalization forms and SQL aggregation functions. It shows how a customer database table is normalized from 1NF to 2NF, an employees skills database from 2NF to 3NF, and a tournament winners database from 3NF. It also provides examples of the OLAP functions ROLLUP and CUBE in Oracle to produce subtotals and cross-tab summaries from aggregated data. Finally, it briefly introduces the architecture of the Oracle Business Intelligence Enterprise Edition (OBIEE).

- 10. OLAP Features in ORACLE ROLLUP: is used to produce subtotals at any level of aggregation needed. These subtotals then “roll up” into a grand total. e.g. SELECT deptno, job, SUM(sal) AS salary FROM emp GROUP BY ROLLUP(deptno,job);
- 11. CUBE: The cube operation calculates all levels of subtotals on horizontal lines across spreadsheets of output and create cross-tab summaries on multiple vertical columns in those spreadsheets e.g. SELECT deptno,job,SUM(sal) AS salary FROM emp GROUP BY CUBE(deptno,job);
