Data management is the crucial aspect for Data Centric Web applications. So far you learnt how to create, read, update and delete data, but data is meant to be shown in so many different ways.
Reading data through View Component is not the only option you have in WebRatio Platform.
Imagine that y...
Usually Web applications are not standalone; they need to integrate with external systems and other applications in the company intranet. The best way to make different applications communicate with one another is to use a Web service infrastructure. That’s why it is important to know how you can ea...

Domain-Specific Modeling (DSM) is the latest approach to software development, promising to greatly increase the speed and ease of software creation. Early adopters of DSM have been enjoying productivity increases of 500–1000% in production for over a decade. This book introduces DSM and offers exam...
When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks. In Domain-Specific Languages , noted software development expert Martin Fowler first provides the in...
