Description
Learning the SQL language is one of the most basic 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 textbook introduces the basics of the SQL language and the Oracle Relational Database Management System (RDBMS). One will become acquainted with the differences in the working environment between a traditional on-premise database installation and the Oracle database service cloud-computing platform.
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.
This textbook takes a unique approach to SQL training in that it incorporates data modeling theory, relational database theory, graphical depictions of theoretical concepts and numerous examples of actual SQL syntax into one learning vehicle.
Audience
The target audience for this textbook is all Oracle professionals, both business and systems professionals. Among the specific groups for whom this textbook 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
Training Suggestions
This textbook may be used as one module within a Sideris textbook kit entitled Oracle Database 12c: SQL – Fundamentals (Levels I & II). When delivered in this format as an instructor-led training (ILT) or live virtual training session, the suggested presentation length of all chapters is between 5 and 6 days.
The sequence in which the modules should be considered is as follows:
Oracle Database 12c: SQL I – Introduction
Oracle Database 12c: SQL II – Intermediate
Certification
This textbook and the subsequent ones within this series consider subjects applicable to certification as an Oracle Database Certified SQL Expert. The topics considered are included within “Exam 1Z0-047: Oracle Database: SQL Certified Expert”.
Objectives
The first portion of this textbook 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, this textbook 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.
