The best code is the one you never need to write. Using code generation and automated builds you can minimize the risk of human error when developing software, but how do you maintain control over code when large parts of it is handed over to a machine? In this tutorial, you will learn how to use open-source software to create and control code automation. You will see how you can generate a completely object-oriented domain model by automatically analyzing your database schemas. Every aspect of the process is transparent and configurable, giving you as a developer 100% control of the generated code. This will not only increase your productivity, but also help you build safer and more maintainable Java applications.

Deep Dive: Alfresco Core Repository (... embedded in a micro-services style a...J V

Alfresco Summit 2014 (London) Though best practice is to leverage Alfresco through the well defined API's, it can be useful to understand the internals of the repository so that your development efforts are the most effective. A deep understanding of the repository will help you to evaluate performance bottlenecks, look for bugs, or make contributions. This session provides an overview of the repository internals, including the major components, the key services, subsystems, and database. We then provide an example where we leverage the repository in a micro-service architecture while building Alfresco's future cloud products and show how the different parts of the repository interact to fulfill requests. http://summit.alfresco.com/london/sessions/diving-deep-alfresco-repository https://www.youtube.com/watch?v=TAE9UjC0xxc

APEX Application Lifecycle and Deployment 20220714.pdfRichard Martens

APEX application deployment is mostly done by exporting the application and importing it into the target environment. But what if your team continuously develops (as they should), where do you stop developing to start preparing your release-deployment? You should be able to deploy based on features; without your developers having to halt their development. Using the deployment-method explained in this presentation you will be able to do just that. The method includes things like Code versioning (GIT), Feature-tickets (Jira), Code Review (Quality), Automated Deployment using Jenkins and Flyway. When implemented you will be able to successfully and predictively deploy your APEX applications (including underlying database objects) to the different deployment-environments. With a few modifications you can even upgrade the methodology to be a "continuous delivery" methodology.

Developing Kafka Streams Applications with Upgradability in Mind with Neil Bu...HostedbyConfluent

Does your organization struggle with updating of its Kafka Streams application? Releasing a new version of a Kafka Streams application can be challenging, especially if its state has to be preserved between releases. Consider these best-practices and architectural ideas to make this process smoother and improve your release process. Having experienced accidental removal of change-log topics and needing to expand partitions, it is much easier to handle with some planning. With the proper planning, you can achieve easier application upgrades. Key take-aways from the session include: * How do minimize the rebuilding of the state-stores. * How to change stream topologies without affecting the existing state stores. * What you can do when you absolutely need to increase the number of partitions within your application. * How to leveraging schemas for application releases. * Measures to prevent data corruption, especially if Kafka is not only your system of record but also your source of truth. * Techniques to support rolling back an application. * The advantages of splitting apart a Kafka Streams application into multiple applications.

More from Roel Hartman (20)

Wizard of ORDSRoel Hartman

This document discusses Oracle REST Data Services (ORDS) and how it can be used to expose database objects like tables, views, procedures, and functions through RESTful APIs. It provides examples of enabling different database objects as REST resources and configuring the exposed APIs. It also covers more advanced topics like parameter passing, result handling, authentication, and protecting resources with OAuth client credentials.

APEX Bad PracticesRoel Hartman

We all make mistakes. Making mistakes is an opportunity to learn. But as a first step you have to recognize the mistakes you made. If you don't, those mistakes might evolve into a practice. A bad practice. But you can also learn from someone else's mistakes. That's why I crowdsourced "Bad Practices" that people have encountered in the wild. And I was suprised by the numerous examples people came up with. So this session will cover real world examples of practices that are labeled as "bad". Of course we will discuss why these practices are bad and what would be the better solution.

Tweaking the interactive gridRoel Hartman

The Interactive Grid is introduced in APEX 5.1 as a best of both worlds of Tabular Forms and Interactive Reports. Although a lot of settings are declaratively avaible within the APEX builder, there are a ton of features built in that are only accessible by JavaScript. In this session you will learn how to use the most interesting "hidden" features with just a few lines of JavaScript. Some examples: - Adding and removing buttons from the Interactive Grid toolbar. - Adding and removing actions from the toolbar menu. - Adding and removing functionality from the row level pop up menu. - Removing complexity on the column level. - Adding tooltips to a column. - Changing the layout of columns and headings. - Refreshing (only) changed records within the grid. - Removing only deleted records from the grid - without a full refresh.

Docker for DummiesRoel Hartman

You might (or might not) have heard of Docker. But you have no idea what it is and why you should care. But if you are a database or APEX developer and still work with Virtual Machines, it is about time to broaden your horizon. In this session you'll learn what Docker is and how you can benefit from it in your daily work. In this presentation we will walk through the following subjects: - What is Docker - Where do I get my images - Pull an image - Start a Docker container / Stop / Restart - Use a Docker container for APEX Development : Via the browser, SQL Developer, SQL Plus, etc - Make host directories accessible within the container - Use scripts to modify the image or create your own one

A deep dive into APEX JET chartsRoel Hartman

In this session we will take a closer look on the options the new JET Charting engine brings to the APEX world. There are a quite a lot of declarative options to explore, but also the JavaScript API is worthwhile to investigate. You will learn that with just a few lines of JavaScript you can change the look and feel of a chart to your own needs. Outline: - What is Oracle JET. - Declarative JET integration in APEX. - Modify the JET charts using Dynamic Actions and a few snippets of JavaScript. - Use other JET components in APEX. - Building an APEX plugin for a JET component

My Top 5 APEX JavaScript API'sRoel Hartman

Oracle Application Express (APEX) is shipped with several JavaScript libraries, jQuery being the best known one of them. And on top of these libraries the APEX Development Team created their own. You probably used a couple of these API's already, like $s, $v etc. But there are way more and some of them are extremely useful. But first you have to be aware they exists. And secondly you have to know how to use the properly. This session will cover the most valuable JavaScript API's with some real world examples. Most developers stick to the standard $s and $v functions - even without knowing there is also a $v2 and $s can have more parameters. The focus will be on the namespaced apex API's, like apex.server.process and apex.event.trigger.

Mastering universal themeRoel Hartman

One of the most important features of Oracle Application Express 5 is the Universal Theme. This theme allows every database developer to create great looking applications without knowing any JavaScript, HTML or CSS. But how do you make changes to comply to your company branding in such a way you don't break anything else? And how do you add new templates and template options? In this session you will learn how the Universal Theme works, what the components are and what you should and shouldn't do when you make your changes.

APEX Developers : Do More With LESS !Roel Hartman

As an APEX Developer you might have experienced that conventional CSS has its drawbacks. And you might have heard about LESS, SCSS, SASS and other weird acronyms. So what do these acronyms mean to you and why should you care? In this session you will learn how to bring your CSS skill set to the next level using the opportunities brought to you by these new techniques. Although these skills can be applied to any web project, in this session we will be targeting APEX applications.

This document discusses automatic testing of APEX applications. It describes different types of tests including acceptance tests, integration tests, and unit tests. It advocates for automating these tests using tools like Selenium to reduce time to market, find defects early, and improve test coverage. Automating unit tests in PL/SQL, integration tests using APIs and components, and acceptance tests using criteria like performance and functionality are proposed. Testing APEX applications with Selenium is demonstrated.

Striving for Perfection: The Ultimate APEX Application ArchitectureRoel Hartman

APEX supports a flexible architecture. That means that there are multiple ways of solving problems like: separation of data and logic, security issues, re-use, including javascript and CSS, etc. etc. In this session I'll give the pro's and cons of each available option. As this is aimed to be an interactive session, the attendees are encouraged to put forward their own ideas - and concerns. So, maybe, in the end, we'll reach the "Ultimate APEX Application Architecture"!

Done in 60 seconds - Creating Web 2.0 applications made easyRoel Hartman

This document discusses how to create Web 2.0 applications using declarative definitions in APEX 4.0 without needing to know JavaScript. It provides examples of specifications that define client-side behaviors using events, actions, and targets. The specifications control behaviors like conditionally hiding/showing fields and changing colors. It also discusses debugging dynamic actions and learning HTML, JavaScript, jQuery, CSS, and the DOM to understand how dynamic actions work.

Tales from a Parallel Universe: Using Oracle 11gR2's Edition Based Redefiniti...Roel Hartman

This document discusses using Edition-Based Redefinitions (EBR) in Oracle Database 11gR2 to perform live application upgrades without downtime. It explains how EBR allows creating parallel application versions or "editions" that contain different objects and code. Sessions can then be switched between editions to test upgrades before cutting over. The document provides examples of renaming tables, creating editioning views, rerouting privileges, and recompiling PL/SQL between editions to perform an upgrade. It also discusses challenges of using EBR with APEX applications and best practices for parallel application versions using EBR.
