2022 has had four product releases loaded with the many features you requested.
While it was challenging to pick only 5 features from the ever-growing list of functionalities, we have collated this list of the top features of 2022 based on the positive feedback we’ve received.
As you probably know, computed attributes are available starting from 4D v19 R3. A blog post is available that presents this great new feature.
As we always propose the best and complete user experience to our mobile app developers, computed attributes are compatible with all your iOS and Android projects.
It is often helpful or even essential that databases be adapted in a flexible and evolving way to users and their businesses in the computer world. The control of accessible data is also a recurrent and sensitive subject. From this point of view, developers use methods and formulas that are sometimes complex to give or restrict access to information, depending on the context or the access rights of the users.
Let’s take a simple example. In your application, you sometimes need to display a list of people. One of the columns displays their full names, but in your database, you have a first name field and a last name field. Currently, you write a formula in the list box column, and you have to manage the sorting on the column yourself. Wouldn’t it be great to have a computed field where you can define its calculation formula and sorting method, and have all the business logic inside the class and not in each interface?
Well, starting with 4D v19 R3, 4D provides a solution to this, with computed attributes.
