Part 1. Introduction to functional declarative design

The first part of this book will introduce you to the intricate and fascinating world of software design, exploring its principles, challenges, and methodologies. Software design transcends mere coding. It is the art and science of translating domain models and requirements into efficient, maintainable code structures. This section sheds light on the pivotal role of software design in managing complexity, the importance of choosing appropriate tools and approaches, and the nuances of different programming paradigms. We examine object-oriented design (OOD) and functional declarative design (FDD), discovering how these frameworks guide decision-making and shape the architecture of software projects.

As we venture further, the focus shifts to the engineering approach in software development, emphasizing systematic, educated, and conscious decision-making over haphazard coding practices. This part of the book underscores the importance of understanding software architecture, the art of making informed decisions at various levels, and the value of domain-specific languages in functional programming. The aim is to equip you with a broad understanding of methodologies, practices, and patterns essential for effective software design and architecture that will help you navigate the complexities of both object-oriented and functional paradigms with ease and proficiency.
