This is an important question for people, who just started the way in Information Technology: what are the most important skills that are in demand today and will be in a bigger demand tomorrow?
We used to have a simple answer: a software developer must know programming languages and tools.
With the shift to Service-oriented architecture (SOA), we added another important skill: a developer should understand business, so s/he can develop meaningful services that reflect business needs.
Under SOA umbrella, professionals are engaged today in Microservices, REST API Modeling Language (RAML), and the Metadata tools, such as DataSense by MuleSoft, and others that extend software semantic evolution.
