Oracle Database: SQL Fundamentals

Course Outline

+++++++++ NOTE ++++++++++

This course content is applicable to versions 11c, 12c, 18c, and 19c.

Overview

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 course 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. This course also considers intermediate-level SQL topics such as writing database queries using the SQL-99 syntax and exploiting the power of built-in functions that extend the capabilities of SQL.

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 course 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.

You will learn how to complete of an application schema definition by creating database objects such as relational views, sequences, synonyms, indexes and others to compliment the table definitions. The crucial topic of data integrity and how this is protected using declarative constraints is covered.

With this course we will also leave the idyllic realm of the learning environment and begin to explore such practical real-world considerations as database object security and database performance.

Target Audience

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

Certification

This course 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 1Z0-071: Oracle Database SQL.
Passing the exam is required for the Oracle Database SQL Certified Associate certification.

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, 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.

This course also demonstrates how one can build intermediate-level and even advanced queries using the SQL-99 join syntax, along with other advanced query topics. It also considers both ANSI/ISO and native Oracle SQL built-in functions and the tremendous power that functions offer to SQL operations. It is difficult for one to use SQL within a production environment without liberal use of the built-in functions. Among many other tasks, the built-in functions allow one to move beyond the use of primitive date data types and values to include timestamps, time zones and to address other realistic date and time challenges. Finally attention is given to how one completes an application schema by creating database objects to compliment table definitions. One cannot implement a production database application simply with table and column definitions but needs to create and manage views, indexes, constraints and other object types.

Oracle Database: PL/SQL Fundamentals

Course Outline

General Description

This course introduces one to Oracle database programming using the PL/SQL programming language. One will learn the syntax, structure and features of the language. This textbook will also lay the foundation for the entire Sideris Oracle PL/SQL programming series, allowing one to progress from introductory topics to advanced application design and programming and finally onto writing complex high-performance applications.

PL/SQL may be considered as one of the basic skill sets required for any Oracle professional, nearly as important as the SQL language itself.

This course will also continue on to show those who are now ready to employ the language in the development of database applications. In particular, the focus of this course will be on the use of database-resident stored program units such as procedures, functions, packages and database triggers. New features introduced with the Oracle 12c release of the database are also explained and demonstrated.

+++++++++ NOTE ++++++++++

This course content is applicable to versions 11c, 12c, 18c, and 19c.

Target Audience

The target audience for this textbook is all Oracle professionals. Among the specific groups for whom this textbook will be helpful are:
• Application designers and database developers
• Database administrators
• Web server administrators

Prerequisites

Oracle Database 12c: SQL Fundamentals

Oracle Certification

This course considers subjects applicable to certification as both an Oracle PL/SQL Developer Certified Associate (OCA) and an Oracle Advanced PL/SQL Developer Certified Professional (OCP). The topics considered are included within "Exam 1Z0-149 Program With PL/SQL". The exam, along with the exam Oracle Database SQL 1Z0-071, is required for the PL/SQL Developer Certified Professional certification.

Course Objectives

This course begins with an explanation of the intent and usage of the PL/SQL programming language for database applications. Important reasons why one should incorporate PL/SQL modules within the application architecture right from the initial design and planning phase are presented. Next one learns how to begin building executable PL/SQL program units. One learns about each of the major segments of a working program and how these interact with each other during program execution, including the important error or exception handling capabilities of the language. The final section goes beyond the basics and begins to explore advanced topics that will be useful later in the Sideris Oracle PL/SQL developer textbook series. One learns techniques and features that allow modular and reusable programs to be developed, increasing productivity and maintainability of database applications.

In addition, this course explains how database-resident program units can be used as part of the overall database application architecture and the benefits realized by doing so. It then builds upon one's knowledge of database-resident program units and applies these to the development of PL/SQL packages. In a production environment most PL/SQL program units should be packaged, and these advanced database programming capabilities along with the benefits of using these are discussed. It concludes with extensive demonstrations on how a particular type of database-resident program unit known as a database trigger can be used as part of an advanced database application design.

News & Offers

PL/SQL is Oracle's procedural extension to industry-standard SQL. Its primary strength is in providing a server-side, stored procedural language. It provides specific syntax for this purpose and the provided Oracle data types are the same datatypes as SQL. Server-side PL/SQL is stored and compiled in Oracle Database and runs within the Oracle executable.
