Working within in 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: 

• Using PL/SQL programming language for database applications and development 
• incorporating PL/SQL modules within the application architecture from the initial design and planning phase  
• The essentials of building executable PL/SQL program units 
• Each of the major segments of a working program and how these interact with each other during program execution,  
• Important error or exception handling capabilities of the language. 
• How database-resident program units can be used as part of the overall database application architecture 
• Applying these new skills to the development of PL/SQL packages. 
• Advanced database programming capabilities and benefits 
• How database triggers can be used as part of an advanced database application design 

Need different skills or topics? If your team requires different topics or tools, additional skills or custom approach, 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.  

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). 

Please note that this list of topics is based on our standard course offering, evolved from typical industry uses and trends. We'll work with you to tune this course and level of coverage to target the skills you need most. Topics, agenda and labs are subject to change, and may adjust during live delivery based on audience interests, skill-level and participation.
