Oracle Database 12c: SQL I Introduction

Request more details:

Description:
Learning the SQL language is one of the key tasks required for the use of a relational database. SQL proficiency is essential for business users, database developers, database administrators and any other database professional. This course introduces the basics of the SQL language and the Oracle Relational Database Management System (RDBMS). Participants become acquainted with the differences in the working environment between a traditional on-­‐premise database installation and the Oracle database service cloud-­‐computing platform. This course incorporates data modeling theory, relational database theory, graphical depictions of theoretical concepts and numerous examples of actual SQL syntax into one learning.
Prerequisites:
The target audience for this course is all Oracle professionals, both business and systems
professionals. Among the specific groups for whom this course will be helpful are:
Business and non-­‐IT professionals
Application designers and database developers
Business Intelligence (BI) analysts and consumers
Database administrators
Web server administrators
Objectives:
The first portion of this course considers the logical models upon which a relational database is based and the various configurations and environments in which you may work with the Oracle database. The next segment focuses on the actual SQL syntax for writing database queries. You will begin with the simplest of queries and then proceed onto moderately complex query scenarios. Finally, the course covers the DDL, DML and transaction control portions of the SQL language that allow one to create, maintain and manipulate application database objects and application data.
Since SQL is an industry standard language, many of the topics presented and many of the skills you will acquire will be applicable to other database platforms, such as Microsoft SQL Server, IBM DB2, the open-­‐source databases MySQL and PostgreSQL, and others.
