Curso de Oracle 11g: SQL Fundamentals I
Duración: 24 hrs
This course introduces students to the fundamentals of SQL using Oracle Database 11g database technology. In this course students learn the concepts of relational databases and the powerful SQL programming language. This course provides the essential SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, and create database objects.
The students also learn to use single row functions to customize output, use conversion functions and conditional expressions and use group functions to report aggregated data. Demonstrations and hands-on practice reinforce the fundamental concepts.
In this course, students use Oracle SQL Developer as the main tool and SQL*Plus is introduced as an optional tool.
This course counts towards the Hands-on course requirement for the Oracle Database 11g Administrator Certification.
Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on
Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on Requirement.
