This book is about the Graph Database Modeling using a simple, straightforward scenario. There are plenty of opportunities throughout the upcoming guides to practice modeling domains and analyzing changes to the model that might need to be made.Neo4j is an open source NoSQL graph database. It is a fully transactional database (ACID) that stores data structured as graphs consisting of nodes, connected by relationships. Inspired by the structure of the real world, it allows for high query performance on complex data, while remaining intuitive and simple for the developer.Using this edition, you'll get to learn the theory of graph database and how to use Neo4j to build up recommendations, relationships, and calculate the shortest route between two locations. With example data models, best practices, use-cases, and an application putting everything together, this book will give you everything you need to really get started with Neo4j. Starting with a brief introduction to graph theory, this book will show you the advantages of using graph databases along with data modeling techniques for graph databases. You'll gain practical hands-on experience with commonly used and lesser known features for updating graph store with Neo4j's Cypher query language. This book includes a lot of background information, helps you grasp the fundamental concepts behind this radical new way of dealing with connected data, and will give you lots of examples of use cases and environments where a graph database would be a great interest.

As we stand at the precipice of the sixth generation of wireless technology, we find ourselves on the verge of a paradigm shift that will redefine our understanding of communication and propel us into a future that was once unimaginable. The advent of 6G heralds an era of boundless possibilities, where the very fabric of our interconnected world will be rewoven with unprecedented speed, capacity, and intelligence. In this book, we embark on a journey into the realm of 6G, exploring its potential, promises, and challenges. I invite you to delve into the intricacies of this groundbreaking technology, to discover its transformative impact on industries, societies, and individuals. From the Internet of Things (IoT) to artificial intelligence, from virtual and augmented reality to autonomous systems, 6G will revolutionize how we perceive and interact with the digital landscape. Building upon the foundations laid by its predecessors, 6G aims to overcome the limitations of its predecessors, pushing the boundaries of what is possible. With its ultra-high speeds and ultra-low latency, 6G will unlock a new level of real-time responsiveness, enabling applications that demand split-second decision-making and immersive experiences that blur the line between the physical and the digital. However, the pursuit of 6G is not without its challenges. As we journey deeper into this technological frontier, we must grapple with issues of privacy, security, and ethics. We must ensure that the benefits of 6G are accessible to all, bridging the digital divide and empowering marginalized communities. Moreover, we must address the environmental impact and sustainability concerns associated with the exponential growth of digital infrastructure. As I pen these words, the development of 6G is still ongoing, with researchers, engineers, and visionaries working tirelessly to shape the future of connectivity. By exploring the emerging trends, innovations, and visions in this book, I hope to contribute to the collective understanding of 6G and ignite conversations that will shape its trajectory.

● An important step in database implementation is the data modeling, because it facilitates the understanding of the project through key features that can prevent programming and operation errors.● In database technologies, some of the new issues increasingly debated arenon-conventional applications, including NoSQL (Not only SQL) databases, whichwere initially created in response to the needs for better scalability, lowerlatency and higher flexibility in an era of bigdata and cloud computing. Thesenon-functional aspects are the main reason for using NoSQL database.● Data modeling has an important role to play in NoSQL environments. The datamodeling process involves the creation of a diagram that represents the meaning of the data and the relationship between the data elements. Thus, understanding is a fundamental aspect of data modeling and a pattern for this kind of representation has few contributions for NoSQL databases.● This edition (3rd) explains a NoSQL data modeling standard, introducing modeling techniques that can be used on document-oriented databases. We have considered Cassandra and Riak NoSQL databases because of the heterogeneous characteristics of each NoSQL database classification so that to fill the knowledge gap by studying the available non-relational databases in order to develop a systematic approach for solving problems of data persistence using these technologies.Ajit.............
