Full Database Insight Through the Lens of a Single Method – Bruno Raeymaekers

While the graphical interface of the 4D database structure is great for getting an overview of the existing tables and fields, once you get to over a hundred tables, it can be awkward to find out certain details like endpoints of relations and definitions of composite indices. Good thing we have the 4D language and flexible interface capabilities to add new perspective to complicated application data structures!

In this user group meeting, Bruno Raeymaekers will give us a fresh look at all the details of your database structure.

4D Info Report Component – Thomas Schlumberger

4D applications play a central role in supporting businesses and institutions around the world… around the clock. That makes it important to understand how the applications are performing in order to tune the code, hardware and networking accordingly for optimal operation.

Out of the box, 4D gives us the Administration Window, which offers an overall view of how the application is running at this very moment. But what if you are, perhaps, not around to look at the Administration Window when an anomaly happens? Maybe users are experiencing slow responses during specific times of the day? Some problems, like memory leaks, build up over days or weeks depending on the situation. What if you are called in to help with an application that you know nothing about?!?

Master Action Building with GitHub – Milan Adamov

Master Action Building with GitHub – Milan Adamov

Project mode in 4D gave us proper version control and was a tremendous step forward for the 4D development environment. Every slightest change in the design environment is reflected in various source files in the project folder, which can be more easily tracked to know what changed in the application when and see the history of such changes over the evolution of the codebase.

Many developers choose to use Git for distributed version control of their 4D projects and GitHub as a centralized site providing storage and management of their application source code. As your development efforts, team, and user base all increase in size, you may need to take advantage of Github’s more advanced features for Continuous Integration/ Continuous Delivery (CI/CD).

CI/CD means introducing more automation in building, testing and deployment, and with Github Actions and 4D you have a veritable toolset to streamline your application production! In this meeting, Milan Adamov will show off some of the master action building skills he has used to provide complex application building and deployment for large scale development projects.

A New Server in 4D v20: WebSocket Server – Speed Up Your Web Clients – Thomas Maul

As it was recently announced, the next LTS release of 4D will offer a very powerful new feature… “4D v20 now includes a built-in WebSocket server, allowing developers to build real-time web applications that can handle large volumes of data and provide a seamless user experience.”

WebSocket is a computer communications protocol that provides full-duplex communication channels (bidirectional flow of data simultaneously) over a single TCP connection. Different from an HTTP server, which only responds to requests, a WebSocket server can not only answer but also push data to a client. Examples of where web WebSockets are used today that you might already be familiar with include chat applications and live dashboards that show current chart or device information, such as temperature of a machine or throughput in a factory.
