After learning how you can create, update, and delete data, here is a new entry in the ORDA series. In this post, you will see how you can query your datastore in an object-oriented mode. With ORDA, queries are lighter, more readable, and you can navigate through the whole data model using object-oriented concepts !
On top of that, ORDA makes it possible to very easily query several related tables, manage recursive relations on the same table, and use several logical operators in a single query. Plus, you don’t have to worry about setting relations between tables … manually or automatically !
After introducing Perfect Forward Secrecy, the security level of 4D Web server has been increased again with the support of HTTP Strict transport Security (HSTS). Henceforth, 4D Web server is compliant with the very latest security protocols. Simply upgrade to 4D v17 and enable HSTS to get the A+ ranking (the highest level) from SSL Labs for your web sites!
Sometimes the information you include in your document is best displayed in columns. Not only can columns help improve readability, but some types of documents – newspaper articles, newsletters, flyers, etc. – are often written in column format. The good news is that with 4D v17, you can henceforth create multi-column documents with 4D Write Pro! And beyond document creation, you can also convert your existing 4D Write documents containing multiple columns.
As in the 4D Write plugin, it’s possible to define the number of columns for an entire document. But here’s a good example where 4D Write Pro exceeds 4D Write: you can also set a different number of columns … per section!
4D v17 introduces ORDA, a major evolution in 4D which is opening a world of new possibilities for 4D developers. To learn more about ORDA and its benefits, check out this post to see how ORDA will change the way you work. In order to guide you through the ORDA exploration, we’ve prepared a series of blog posts fully dedicated to the core concepts and related features. This blog post will detail how you can perform CRUD operations on your database with ORDA. CRUD is an acronym for the four basic operations you can perform on data: Create, Read, Update, and Delete.
Imagine a way of using your database with an object-oriented approach, without worrying about its physical structure. Imagine that you could maintain multiple current selections at the same time or that you could perform recursive queries in a single line of code. Well, this is now a reality thanks to ORDA! With 4D v17, your code can be written in an object-oriented mode, and you can easily navigate through your entire data model.
ORDA was one of the major announcements of 4D Summit 2018, opening a world of new possibilities in 4D. It’s now time to give you more details about the ORDA features available with 4D v17. To do so, we’ve prepared a series of blog posts dedicated specifically to ORDA core concepts and related features. And we’ll release them, one after another, day after day.
We are thrilled to announce the launch of beta testing for 4D v17! This major release is chock-full of enhancements and new features that one blog post is not enough to cover them!
With that being said, 4D v17 Beta introduces more than +60 advances including improvements to existing functionalities as well as new ones. And if you’re eager to see 4D v17 Beta in action, check out this extensive library of examples (HDIs) to have an overall idea on this release full potential.
So, let’s take a look and discover some of what 4D v17 Beta has in store for you:
- ORDA: a revolutionary concept, making it possible to use your database in an object-oriented approach.
- 4D language: major enhancements to help you boost your productivity with fewer lines of code.

All of this, and more awaits you!
As a developer, you often need to know whether a specified item already exists in a collection, or to find all the items corresponding to particular criteria. 4D collection methods offer many different ways to look up specific items.
