Lycia Components Included in QPM

With Querix Package Manager, you can install the following Lycia components:

Runtime is an execution environment for Lycia applications.

4GL compiler is implemented in Lycia for working with 4GL code. Lycia compiler Digitally Transforms I4GL applications.

All 4GL programs compiled by Lycia automatically become web services with a REST API. It is up to the system manager how much of these services should be available to the outside. Also, all such programs can be hot-deployed, eliminating the need to ask people to log off before any update. They are containerized and can float around the cloud with no need to inform the clients / end users. Automatic/Manual Load Balancing is also easy to do using standard tools.

The front end can be enhanced using CSS as well as other extensions in the language.

All programs are Accessibility-enabled and run through any standard modern browser.

JSON, XML, Java integration, messaging, and Streaming are also part of the Lycia 4GL language. Other languages can easily interact with Lycia programs.

All programs are compiled to LLVM and use sophisticated optimization technique to achieve exceptional performance.
