Primary Breadth-First Development (PBFD): An Approach to Full Stack Software Development

Abstract

Full stack software applications are often simplified to basic CRUD operations, which can overlook the intricate principles of computer science necessary for addressing complex development challenges. Current methodologies frequently fall short in efficiency when managing these complexities. This paper presents an innovative approach that leverages foundational computer science principles, specifically using Directed Acyclic Graphs (DAGs), to model sophisticated business problems. We introduce Breadth-First Development (BFD), Depth-First Development (DFD), Cyclic Directed Development (CDD), Directed Acyclic Development (DAD), Primary BFD (PBFD), and Primary DFD (PDFD), to enhance application development. By employing bitmaps, this approach eliminates junction tables, resulting in more compact and efficient data processing within relational databases. Rigorous testing and over eight years of production deployment for tens of thousands of users have yielded remarkable results: zero bugs, development speed improvements of up to twenty times, performance gains of seven to eight times, and storage requirements reduced to one-eleventh compared to traditional methods.
