Systems Analysis and Synthesis: Bridging Computer Science and Information Technology (Paperback)

Systems Analysis and Synthesis: Bridging Computer Science and Information Technology presents several new graph-theoretical methods that relate system design to core computer science concepts, and enable correct systems to be synthesized from specifications. Based on material refined in the author’s university courses, the book has immediate applicability for working system engineers or recent graduates who understand computer technology, but have the unfamiliar task of applying their knowledge to a real business problem.

Starting with a comparison of synthesis and analysis, the book explains the fundamental building blocks of systems―atoms and events―and takes a graph-theoretical approach to database design to encourage a well-designed schema. The author explains how database systems work―useful both when working with a commercial database management system and when hand-crafting data structures―and how events control the way data flows through a system. Later chapters deal with system dynamics and modelling, rule-based systems, user psychology, and project management, to round out readers’ ability to understand and solve business problems.

• Bridges computer science theory with practical business problems to lead readers from requirements to a working system without error or backtracking
• Explains use-definition analysis to derive process graphs and avoid large-scale designs that don’t quite work
• Demonstrates functional dependency graphs to allow databases to be designed without painful iteration
• Includes chapters on system dynamics and modeling, rule-based systems, user psychology, and project management

《系統分析與綜合：連結計算機科學與資訊技術》介紹了幾種將系統設計與核心計算機科學概念相關聯的新圖論方法，並能根據規格合成正確的系統。本書基於作者在大學課程中精煉的材料，對於了解計算機技術但對於將知識應用於實際業務問題感到陌生的系統工程師或最近畢業的學生具有即時的應用價值。

從合成和分析的比較開始，本書解釋了系統的基本構建塊-原子和事件-並採用圖論方法進行數據庫設計，以鼓勵設計良好的模式。作者解釋了數據庫系統的工作原理-在使用商業數據庫管理系統和手工創建數據結構時都很有用-以及事件如何控制數據在系統中的流動方式。後面的章節涉及系統動態和建模、基於規則的系統、用戶心理學和項目管理，以提高讀者理解和解決業務問題的能力。

本書將計算機科學理論與實際業務問題相結合，引導讀者從需求到一個無誤或無需回溯的工作系統。它解釋了使用定義分析來推導過程圖，避免不完全正確的大規模設計。演示了功能依賴圖，使得可以無需痛苦的迭代設計數據庫。還包括有關系統動態和建模、基於規則的系統、用戶心理學和項目管理的章節。
