Mastering dataclass search in your 4D application

Since the introduction of ORDA in 4D, many developers have become accustomed to writing database queries using a new syntax.

But do you really know what the 4D engine is capable of?

Starting with conventionally coded applications, we’ll see how to enhance and add functionality step by step to a search engine in the “4D spirit”. Our research will unlock the power of 4D for you as a developer as well as for your users – by taking full advantage of the .query() member function on data classes.
