Collections are PL/SQL's approach to arrays. We have three types of collections (associative arrays, nested tables, varrays) and this presentation explores both the common features of these datatypes, and their differing characteristics. Copyright 2016 Oracle Corporation.
Turbocharge SQL Performance in PL/SQL with Bulk ProcessingSteven Feuerstein
Is your Oracle Database application running slower than you'd like? One of the first things to check is row-by-row processing: non-query DML (insert, update, delete) within a loop. And the fix? Bulk processing, either with smarter SQL or with FORALL and BULK COLLECT in PL/SQL.

Users hate to wait - for anything. For our applications to be successful, they not only must be correct (meet user requirements) and maintainable. They must also execute efficiently enough to avoid user frustration. This presentation offers a whirlwind introduction to the most important techniques for improving PL/SQL performance, including data caching, FORALL and BULK COLLECT, the function result cache and the new 12.1 UDF pragma. It will help you proactively identify opportunities for applying techniques that will most dramatically (generally, an order or magnitude or more) improve the performance of your PL/SQL code. https://oracle.com/plsql
PL/SQL is a combination of SQL along with the procedural features of programming languages.
It provides specific syntax for this purpose and supports exactly the same datatypes as SQL.
Oracle REST data service is a powerful utility to publish an Oracle database into a REST based webservice. This presentation will focus on basic installation of ORDS in a Tomcat server, PLSQL apis for publishing a REST service and securing the REST endpoints
Procedures in pl/sql,CREATE PROCEDURE Syntax, Compiling and Showing Errors, Parameters, Defining the IN, OUT, and IN OUT Parameter Modes, Parameter Constraint Restrictions, Example – Procedure with No Parameters,Example – Passing IN and OUT Parameters, Dropping a Procedure
Javascript has taken over the world of apps. It is the language for Internet and mobile app development. And Javascript developers want to work with JSON as their primary data structure of choice. Relational database developers can moan about a lack of concern for data integrity, consistency, etc. But that won't stop anybody. So maybe we should give them the best of both worlds: work with JSON, but store and manipulate that JSON data in a powerful, fast, secure relational database: Oracle Database. This presentation introduces attendees to Oracle Database 12c features that make it easy to work with JSON in the database, through PL/SQL, and to publish REST APIs to those PL/SQL calls.

How to Find Patterns in Your Data with SQLChris Saxon
An introduction to the pattern matching clause, match_recognize, introduced in Oracle Database 12c. This allows you to use regular expressions to search your data using SQL.
PL/Scope is a compiler tool that gathers information about identifiers (as of 11.1) and SQL statements (as of 12.2) in your PL/SQL code. You can do all sorts of amazing deep-dive analysis of your code with PL/Scope, answering questions like: Where is a variable assigned a value in a program? What variables are declared inside a given program? Which programs call another program (that is, you can get down to a subprogram in a package)? Find the type of a variable from its declaration. Show where specific columns are referenced. Locate all SQL statements containing hints. Find all dynamic SQL usages – ideal for getting rid of SQL injection vulnerabilities. Show all locations in your code where you commit or rollback. In other words, powerful impact analysis, built right into PL/SQL!
Consistent, robust error management is a critical feature of any successful application. Developers need to know all that is possible in PL/SQL regarding the raising, handling and logging of errors, and that standardize the way in which those tasks are performed. This presentation takes you beyond the basics of exception handling in PL/SQL to explore the wide range of specialized error management features in Oracle. We will cover FORALL's SAVE EXCEPTIONS, DML error logging with the DBMS_ERRLOG package, the AFTERSERVERERROR trigger, the DBMS_UTILITY.FORMAT_ERROR_BACKTRACE function, and more. Use this material to help you fully leverage PL/SQL error management features, making it easier to identify the sources of problems and fix them more rapidly. https://oracle.com/plsql

This slide deck was used in the May 2017 CodeTalk conversation, hosted by Steven Feuerstein of Oracle, sponsored by ODTUG and IOUG, with three people actively using utPLSQL to test their code - and also build out v3 of the utPLSQL framework: Jacek Gabal * Pavel Kaplya * Stefan Poschenrieder.
Oracle Application Express and PL/SQL: a world-class comboSteven Feuerstein
Ah, the joy of a low-code development tool like Application Express! You point, you click, and you get beautiful, powerful websites and mobile apps. But you will also almost certainly need to write some SQL and PL/SQL to complete the functionality of that application. Sadly, there is always a tendency when writing code within a point-and-click development environment to treat that code rather casually; after all, it is not the really important (user-facing) part of the application, right? Wrong! It’s all important, and it is way too easy to create an awful mess in your otherwise elegant APEX app if you treat your SQL and PL/SQL code as “second class citizens” in terms of the attention you give to it. Not to mention bad performance or maintenance nightmares! In this session, Steven will offer some recommendations for how best to write and manage your SQL and PL/SQL in your APEX applications, as well as cover key features in PL/SQL you should be leveraging.

Java Community and Overview Track - July 2015 Yolande Poirier
The presentation introduced the Virtual Technology Summit in July 2015. It gives an update about Java releases and new members in the Java community as well as links to Java articles
This presentation was the intro video to the Virtual Technology Summit in September 2015. It gives an update about the Java releases and community updates.
Waaaaay back in the mid-2000s I did a bunch of presentations on unit testing, test driven development, and so on. I offer this slide deck in memory of those days (and ah the relative simplicity of those Powerpoint themes, mine anyway). You might still find this useful.
Woo hoo!

Triggers, more specifically DML triggers, are blocks of code that run automatically when the associated event occurs on a table. Some developers use them a lot. Many others say “Never use triggers!” What’s a DB dev to do?
In our September 3 2019 PL/SQL Office Hours, Chris Saxon and Steven Feuerstein explore some of the nuances of triggers and have a BIG ARGUMENT over how and when they should be used. Well, OK, maybe not a BIG argument. But we’ll be happy to argue with anyone who shows up. Well, not ARGUE, exactly.
Guest appearances from Toon Koppelaars, of the Oracle Real World Performance Team, and Jacek Gebal of utPLSQL v3 fame.
Here are the slides.
Oracle PL/SQL 12c and 18c New Features + RADstack + Community SitesSteven Feuerstein

I used this small slide deck on July 3 2018 for my Ask TOM Office Hours session on dynamic SQL. You can watch the recording here: https://devgym.oracle.com/pls/apex/dg/office_hours/4486
The Amazing and Elegant PL/SQL Function Result CacheSteven Feuerstein
The Function Result Cache, introduced in Oracle Database 11g, offers a very elegant way to cache cross-session data and make it available via PL/SQL functions. It can have a dramatic performance impact on fetching static data (even static for just a period of time) - and it's managed automatically by Oracle Database for you!
The Oracle PL/SQL compiler does much more than compile code. It also automatically optimizes code, supports conditional compilation, and compile-time warning (lint checking).
utPLSQL offers a unit testing API for PL/SQL that is modeled on the xUnit approach. This is an old slide deck on utPLSQL so my apologies for any inconsistencies with the current utility. Note: while I created the original utPLSQL code base, I am not actively working on utPLSQL at this time. Check out github.com/utplsql for the code and project details.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
