Perth APAC Groundbreakers tour - SQL TechniquesConnor McDonald
Get more out of the database by exploiting the rich suite of features available with the SQL language. We cover pivot, unpivot, rollup, pagination, error logging, query block naming
Sangam 18 - Database Development: Return of the SQL JediConnor McDonald
A look at the techniques that middle tier developers can employ to get greater value out of their applications, simply by having an understanding of how the database works and how to make it sing.
Explanations and examples of all of the flashback features available in the Oracle Database:
- flashback query
- flashback table
- flashback drop
- flashback database
- flashback transaction
- flashback data archive
OpenWorld 2018 - Common Application Developer DisastersConnor McDonald
Two of the critical requirements of a database are:
- run fast
- data integrity
The database can achieve these things, but only as long as you understand the mechanisms correctly. If you don't, then things can go downhill fast.

Kscope19 - Flashback: Good for Developers as well as DBAsConnor McDonald
Flashback is not only for those "Oh No!" moments when we make a mistake. It enables benefits for developers ranging from data consistency to continuous integration and data auditing. Tucked away in Enterprise Edition are six independent and powerful technologies that might just save your career—they will also open up a myriad of other benefits of well.
18(ish) Things You'll Love About Oracle Database 18cChris Saxon
An overview of the latest SQL & PL/SQL features in Oracle Database 18c, including:
- Polymorphic Table Functions
- Inline External Tables
- JSON improvements
By expanding our knowledge of SQL facilities, we can let all the boring work be handled via SQL rather than a lot of middle-tier code, and we can get performance benefits as an added bonus. Here are some SQL techniques to solve problems that would otherwise require a lot of complex coding, freeing up your time to focus on the delivery of great applications.

Latin America Tour 2019 - slow data and sql processingConnor McDonald
Well done! You've come up with the killer idea for 2020. You've got the best UI design anyone has ever seen! Your modern application ticks all the boxes — serverless, functional, Kubernetes, microservices, API-based, the list goes on. It runs on every OS and every type of device. But unfortunately, all of this counts for absolutely NOTHING if your data access is slow or buggy. But an Autonomous database will fix all that right? Only if you understand the fundamentals of how SQL is processed by the database. For novice developers, SQL can be hard to understand and sometimes totally hidden from view under an ORM. Let's peel back the covers to show how SQL is processed, how to avoid getting hacked, and how to get data back to your application in a snappy fashion.
A story about developing an application for an online store, persisting all the data as JSON.

Some lesser known SQL features that can boost developer productivity.
- query expansion
- temporal validity
- ANSI fetch first
- cross join

- error logging
Added in Oracle Database 18c, Polymorphic Table Functions (PTFs) allow you to change the shape of a result set at runtime. So you can add or remove columns from your results based on input parameters.
This presentation gives an overview of the why & how of PTFs.
Another year goes by, and most likely, another data access framework has been invented. It will claim to be the fastest, smartest way to talk to the database, and just like all those that came before it, it will not be. Because the best database access tool has been there for more than 30 years now, and that is PL/SQL. Although we all sometimes fall prey to the mindset of “Oh look, a shiny new tool, we should start using it," the performance and simplicity of PL/SQL remain unmatched. This session looks at the failings of other data access languages, why even a cursory knowledge of PL/SQL will make you a better developer, and how to get the most out of PL/SQL when it comes to database performance.

Analytic functions that came way back in 8i are cool, but often we use them really to answer questions about the patterns that exist in data. So perhaps it is time for a new SQL syntax - one more closely aligned with finding patterns, rather than analytical computations. Enter the MATCH_RECOGNIZE syntax!

Most people think of the Flashback features in Oracle as the "In Case of Emergency" switch, to only be used when some catastrophe has occurred on your database. And while it is true that Flashback will definitely help you 3 seconds after you press the Commit button and you realise that you probably needed to have a WHERE clause on that "delete all rows from the SALES table" SQL statement. Or for when you run "drop table" on the Production database, when you were just so sure that you were logged onto the Test system. But Flashback is not only for those "Oh No!" moments. It enables benefits for developers ranging from data consistency to continuous integration and data auditing. Tucked away in Enterprise Edition are six independent and powerful technologies that might just save your career—they will also open up a myriad of other benefits of well.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
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.

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.

- then either tell me or do it for me when needed
we need something better…
And its not something "NEW" in 18c, or 12c, ….

And the second thing about running a statement well is that even with the best statistics we might still have to make some adjustments and it is best to make those adjustments midstream than waiting for the statement to finish and putting the customer through all of that pain and only then being able to make adjustments on subsequent executions

We will concede that over a number a releases, we've introduced, enhanced, re-thought a LOT of things with regard to the optimizer..
… which can make things feel a little overwhelming.

1) run my SQL as good as it can be run
… or at least TRY to
2) and when you've got it running good…
for god sakes, don't change anything. Just keep running it good… all the time, exactly like it is today….
"….but … I don’t want to look like a fool, so if you DO find something better…."
then please tell me…
BUT DON"T TOUCH ANYTHIING.
Let *me* decide if this is a good switch to make.

So when it comes to running stuff well, the two elements we would focus on are
- better statistics so the chances of getting a good plan are better
- and a recognition that no matter how good the statistics are there will always be challenges for the optimizer so it needs the ability to change course mid-stride

These are just some slides I ripped out of existing decks, obviously they would be cleaned up and formatted as we see fit but really just to touch on some of the things in 12c whether it be release 1 or release 2
