This book is prepared to answer the demands for the practical guidance of systems analysis and design methods. The author hopes that after reading this book, the reader can understand the concepts and techniques to analyze and design the systems. 

In general, there are 2 (two) main methods that most often used in system development: structured and object-oriented methods. The book explains a significant paradigm difference between the two methods of analyzing and designing the systems. The author expects the readers can distinguish that paradigm as well as analyze and design using both methods. 

The book structure starts from the concept to technical. The author uses the Unified Modeling Language (UML), which is widely used, for documenting object-oriented modeling. The UML has proven its ability to document and model the systems on a large, medium, and small scale.
