Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

We want to process a set of organizations from different industries to perform various queries about them using concepts from the functional paradigm. For each organization we know its name, website and other important fields. The main goal is to focus on modeling the data types and writing the necessary functions to perform the required analysis.
