Getting Started with the Graph Query Language (GQL): A complete guide to designing, querying, and managing graph databases with GQL

Learn how to build and query graph databases with this first comprehensive guide to ISO-standard GQL, featuring 50+ hands-on examples and a real-world case study that will change the way you work with connected dataFree with your book: DRM-free PDF version + access to Packt's next-gen Reader*Key FeaturesGo beyond theory and apply key concepts and syntax through interactive tutorials and practical examples via the GQL PlaygroundLeverage advanced features of GQL to manipulate graph data efficientlyExplore GQL applications in data analytics and discover how to leverage graph knowledge in real-world scenariosPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionGraph Query Language is becoming the go-to standard for graph databases, especially with its support for interconnected analytics and GenAI capabilities. This book comes from a team of industry veterans who know exactly how to break down the fundamental GQL concepts, graph terms, definitions, catalog systems, and everything that matters in actual work.You’ll get to grips with graph data types, value expressions, graph matching patterns, and modifying statements through practical GQL examples. Once you've got the basics down, you’ll tackle advanced GQL topics such as path modes, complex path matching patterns, shortest path queries, composite statements, session and transaction commands, and procedures. You’ll also learn to create extensions and understand the design of graph databases to solve industry issues. The authors cover techniques like property graphs to help you optimize your graph queries and offer insights into the future of GQL and graph technology.By the end of this book, you’ll confidently query and update graph data, run graph algorithms, create visualizations, and apply your learnings to a real-world use case of money flow analysis for assessing bank client behaviors and detecting transaction risks.*Email sign-up and proof of purchase requiredWhat you will learnExperiment with GQL syntax on GQL Playground, including MATCH, RETURN, INSERT, UPDATE, and DELETEWork with operators, functions, and variables in an organized fashionBecome familiar with complex topics such as varying path matching modes, repeated variables, shortest path, procedures, and transactionsEnhance execution speed through indexing or caching systemsUnderstand how to manage access control effectivelyTackle real-world issues with a case study focused on money transaction analyticsWho this book is forThis book is for graph database developers, DBAs, programmers, data engineers, and analysts who want to learn the new graph database standard GQL. A basic understanding of graph and relational databases, data models, knowledge of SQL basics, and programming will make the content easy to grasp. While it is designed to be accessible even if you don’t have a background in graph theory, familiarity with concepts like nodes, edges, relationships, and the distinction between directed and undirected graphs will enhance your learning experience.Table of ContentsEvolution Towards Graph DatabasesKey Concepts of GQLGetting StartedBasic GQL StatementsOperators and Logical ControlFunctionsAdvanced ClausesTransaction ManagementSessions ManagementConformance to GQL StandardBeyond the GQL StandardA Case StudyThe Evolving Landscape of GQLGlossary and Resources Read more
