SIMQIN
SIMQIN
Today, XML is a widespread standard in multi-media and cross-platform publishing of technical documentation. Many editing programs, management systems and publication tools, as well as many industry standards, are now based on XML. Nevertheless, XML has not yet been able to break through in all areas, because the format has a very clear separation between the structure and the layout of documents. Editors still prefer to work with word processors such as Microsoft Word: here, the text and the document layout are created almost simultaneously and can be immediately checked on screen. Working with XML, on the other hand, requires a sense of the abstract – the text flow is broken up by tags of the document structure. The layout only follows at a further stage in production. SimQin shows the document in layout mode from the outset. Additionally, however, the XML document structure and organisation are made visible.Starting Price: Free -

OrigoDB
Origo
OrigoDB enables you to build high quality, mission critical systems with real-time performance at a fraction of the time and cost. This is not marketing gibberish! Please read on for a no nonsense description of our features. Get in touch if you have questions or download and try it out today! In-memory operations are orders of magnitude faster than disk operations. A single OrigoDB engine can execute millions of read transactions per second and thousands of write transactions per second with synchronous command journaling to a local SSD. This is the #1 reason we built OrigoDB. A single object oriented domain model is far simpler than the full stack including a relational model, object/relational mapping, data access code, views and stored procedures. That's a lot of waste that can be eliminated! The OrigoDB engine is 100% ACID out of the box. Commands execute one at a time, transitioning the in-memory model from one consistent state to the next.Starting Price: €200 per GB RAM per server -

Nooku
Logic Labs Digital Solutions
Nooku is a low-code platform and desktop application designed for less technical designers or developers. It enables users to create web apps quickly. Nooku is similar to VS Code but is specifically designed for non-coders or those with minimal coding experience. Nooku not only lets users design their applications, but also allows them to add logic through its workflow builder. How Nooku works: Unlike other no-code tools on the market, Nooku operates directly on your system. While most no-code platforms store your app data in JSON format and render that data into the user interface, nooku interacts directly with your files. Each time you create, open, or edit a new file (page, component, etc.), Nooku reads that file directly from your filesystem. It then generates an Abstract Syntax Tree (AST) for that file and renders that AST in the Nooku editor.Starting Price: $15/month -
