Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book presents a comprehensive overview of fundamental issues and recent advances in graph data management. Its aim is to provide beginning researchers in the area of graph data management, or in fields that require graph data management, an overview of the latest developments in this area, both in applied and in fundamental subdomains. The topics covered range from a general introduction to graph data management, to more specialized topics like graph visualization, flexible queries of graph data, parallel processing, and benchmarking. The book will help researchers put their work in perspective and show them which types of tools, techniques and technologies are available, which ones could best suit their needs, and where there are still open issues and future research directions. The chapters are contributed by leading experts in the relevant areas, presenting a coherent overview of the state of the art in the field. Readers should have a basic knowledge of data management techniques as they are taught in computer science MSc programs.

In Defending Humanity, internationally acclaimed legal scholar George P. Fletcher and Jens David Ohlin, a leading expert on international criminal law, tackle one of the most important and controversial questions of our time: When is war justified? When a nation is attacked, few would deny that it has the right to respond with force. But what about preemptive and preventive wars, or crossing another state's border to stop genocide? Was Israel justified in initiating the Six Day War, and was NATO's intervention in Kosovo legal? What about the U.S. invasion of Iraq?
In their provocative new book, Fletcher and Ohlin offer a groundbreaking theory on the legality of war with clear guidelines for evaluating these interventions. The authors argue that much of the confusion on the subject stems from a persistent misunderstanding of the United Nations Charter. The Charter appears to be very clear on the use of military force: it is only allowed when authorized by the Security Council or in self-defense. Unfortunately, this has led to the problem of justifying force when the Security Council refuses to act or when self-defense is thought not to apply--and to the difficult dilemma of declaring such interventions illegal or ignoring the UN Charter altogether.
Fletcher and Ohlin suggest that the answer lies in going back to the domestic criminal law concepts upon which the UN Charter was originally based, in particular, the concept of "legitimate defense," which encompasses not only self-defense but defense of others. Lost in the English-language version of the Charter but a vital part of the French and other non-English versions, the concept of legitimate defense will enable politicalleaders, courts, and scholars to see the solid basis under international law for states to intervene with force--not just to protect themselves against an imminent attack but also to defend other national groups.

This book constitutes selected papers presented at the 5th International Workshop on Software Foundations for Data Interoperability, SFDI 2021, held in Copenhagen, Denmark, in August 2021. The 4 full papers and one short paper were thorougly reviewed and selected from 8 submissions. They present discussions in research and development in software foundations for data interoperability as well as the applications in real-world systems such as data markets.

Graph data modeling and querying arises in many practical application domains such as social and biological networks where the primary focus is on concepts and their relationships and the rich patterns in these complex webs of interconnectivity. In this book, we present a concise unified view on the basic challenges which arise over the complete life cycle of formulating and processing queries on graph databases. To that purpose, we present all major concepts relevant to this life cycle, formulated in terms of a common and unifying ground: the property graph data model-the pre-dominant data model adopted by modern graph database systems. We aim especially to give a coherent and in-depth perspective on current graph querying and an outlook for future developments. Our presentation is self-contained, covering the relevant topics from: graph data models, graph query languages and graph query specification, graph constraints, and graph query processing. We conclude by indicating major open research challenges towards the next generation of graph data management systems.
