The UML . Designing Real-Time Systems, Parallel and Distributed Applications" is a fascinating and deep dive into the world of designing complex software systems, written by a team of authors with extensive experience in software development. This publication will become an indispensable assistant for students, graduate students, as well as practicing developers and system architects seeking to expand their knowledge in the field of UML (Unified Modeling Language) and its application in real projects. From the first pages, the book captures the reader's attention, offering not just theoretical calculations, but also practical examples that help to better understand how to apply UML to the design of real-time systems, parallel and distributed applications. The reader is immersed in a world of complex algorithms, interactions and architectural solutions that become the basis for the creation of effective and reliable software systems. One of the key themes of the book is the use of UML to describe dynamic systems that require a high degree of reliability and speed. The authors examine in detail how various UML diagrams from class diagrams to sequence diagrams can be used to visualize and analyze the behavior of systems, which is especially true in conditions of parallel and distributed data processing. This makes the book particularly valuable for those working in software development for mission-critical applications, such as management systems, financial platforms, and telecommunications solutions. The book will be of interest not only to professional developers, but also to technical students who want to understand more deeply how modern software systems are designed. It can be an excellent addition to training courses in software engineering, systems analysis, and software architecture. Readers interested in new technologies, development methodologies and current trends in the field of IT will also find a lot of useful information in it. The style of the authors is characterized by accessibility and clarity of presentation, which allows even complex concepts to be explained in simple and understandable language. This makes the book an excellent choice for both beginners and experienced professionals. The team of authors includes experts with many years of experience in software development, which adds additional value and authority to the book. In addition to the main content, the book touches on important aspects of design, such as change management, testing and system validation, as well as issues related to the integration of various components into a single architecture. These topics make the publication relevant not only for the development of new systems, but also for the support and modernization of existing solutions.
