Even though the 4D Data Explorer is still in Preview version (there are certainly more features to come in the next versions), we thought we’d show you the product in action and let you discover its capabilities.
This is a web browser interface usable by the administrator as well as the developer, remotely (in a secure way with an HTTPS connection) or locally on the same machine as your opened database.
Need to check your data during development? Need to find data that could cause bugs? The Data Explorer, with its powerful query engine and intuitive web interface, is made for you!
Let’s watch the video:
Nowadays, web applications are essential modern tools. As machines and processors become more and more powerful, your web applications must constantly meet performance requirements. This is why with 4D v18 R6, the 4D Web Server offers a new kind of web session: the scalable Web session.
Let’s find out more!
As a 4D developer, you may have dreamed of visualizing your data immediately and easily while you update/create it. Or maybe you’re a 4D administrator and you need to quickly find a record that causes an error due to inappropriate data. This has been possible with 4D’s built-in query interface and output form, but it can take time to customize this form and you may need a more responsive tool.
How about a modern and user-friendly web interface to view your data? And for a cherry on the top, what if this interface comes with a powerful query engine? Dream no more! All this is now a reality thanks to Data Explorer, a new tool provided as a Preview for you to evaluate it and give us your feedback.
Of course, it will be enhanced in future versions.
Let’s discover it now!
In this blog post, you discovered the power that shareable entity selections can offer. 4D focuses on data sharing because, in the long run, it leads to performance.
But we’re aware that this strategy might not be your current strategy. We’ve followed the discussions on the forum and understood your comments and feelings.
To soften this step and give you more flexibility and tools, we’ve made some enhancements regarding the nature (shareable or non-shareable) of entity selections.
4D v16 R6 introduced a new concept of communication between processes: shared object and shared collection variables! Thanks to this, you’re able to easily share information between processes.
Until now, entity selections weren’t shareable between processes. However, that has changed … we’re pleased to announce that in 4D v18 R5 entity selections are shareable!
Gone are the days of building a list of primary keys to move a selection of entities to another process. Enhance your multi-processes code by including ORDA entity selections as shared objects.

4D v18 R4 and ORDA made it possible for you to create high-level class functions above the data model. This allows you to write business-oriented code to hide complexity, reduce errors, and speed up the development process.
With 4D v18 R5, we’re bringing even more features to help you optimize and organize your code. For example, you might need to run a function locally on the client to improve performance when working in client/server mode. It’s now possible! Or if you expose your database as a REST server, you might want some functions to be available on the server-side but hidden for your REST clients. This is also possible!
By now you’re aware of the availability of ORDA classes. In this blog post, you’ll learn a few handy tips to get the most out of them!
Let’s see it in action!
In a previous blog post, we introduced you to the world of ORDA data model classes. Now it’s time to get our hands dirty and learn more!
You already know that ORDA’s structure (datastore, dataclass, entity, entity selection) is made up of objects. But they’re not just objects, they’re strongly-typed objects linked to specific ORDA classes. This means that you can write functions to hide the complexity of your data’s physical implementation.
