What are Groovy and Grails primarily used for?
Being a general purpose programming language, Groovy has a wide range of uses. However, Groovy’s strength really shows in its ability to easily define internal Domain Specific Languages (DSLs). Many organizations have adopted Groovy as an abstraction layer for defining business rules using DSLs. Grails is a web framework that is used in a variety of contexts from early stage pro-totyping, to being the platform that organizations base their entire web infrastructure on. Grails is particularly appropriate for building content-centric web applications such as custom Content Management Systems (CMS).
