Slides for the lowcode-book.com - Chapter 1: Basic Low-code questions and answers.

The Low-code handbook -> Learn how to unlock faster and better software development with low-code solutions.

Low-code development represents a paradigm shift in software creation, aiming to expedite application delivery by minimizing manual coding. In a time when software demand is escalating across all sectors and the availability of skilled programmers is limited, low-code emerges as a potential solution to deliver high-quality software more efficiently.

This book seeks to unravel the intricacies of low-code development. It addresses questions such as: Who is it for? What types of applications can be developed using low-code? How can one optimize the quality and volume of the code produced? How does one select the most suitable tool, or even create your own, tailor-made, solution?

Providing pragmatic and comprehensive answers to these questions, this book equips readers with the necessary knowledge to understand and navigate the low-code landscape. It is structured into ten chapters that delve into both the technical and societal aspects of low-code, its relationship with other software development paradigms, and the potential role of Artificial Intelligence within the low-code movement. Furthermore, it explores how low-code methodologies can be utilized to develop intelligent software applications.

As low-code development continues to gain mainstream acceptance and market share, this book serves as a highly valuable resource for anyone looking to understand and leverage this emerging approach to software development.
