Gain the Core Skills Required to Setup, Run, and Manage Databases using PL/SQL and Oracle Database Technology
Course Snapshot
Overview
Oracle 19c PL/SQL Fundamentals is a three-day, hands-on course that introduces Oracle database programming using the PL/SQL programming language. Throughout the course, students will explore the core syntax, structure, and features of the language. This course will also lay the foundation for the entire 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.
The course also explores applying the newly learned skills to the development of database applications. Participants will learn how to use database-resident stored program units such as procedures, functions, packages, and database triggers. Students will also learn about the latest features in Oracle 19c.
NOTE: This training is NOT Official Oracle University training. This is independent, adjustable content that aligns with current topics, skills, and tools that participants need to excel in these areas.
Learning Objectives
Working within a hands-on learning environment, guided by our expert team, attendees will develop a practical approach to Oracle Database Technology. Throughout the course, participants will explore:
Need different skills or topics? If your team requires different topics or tools, additional skills, or custom approaches, this course may be further adjusted to accommodate. We offer additional Oracle, database, scripting, administration, programming, security, and other related topics that may be blended with this course for a track that best suits your needs.
Audience & Pre-Requisites
This course is geared for anyone needing to interface with an Oracle database such as end users, business analysts, application developers, and database administrators / DBAs. Attendees should have incoming basic SQL experience, as well as an understanding of databases (required to manipulate it with PL/SQL).
