LogiQL: A Query Language for Smart Databases (Emerging Directions in Database Systems and Applications)

''This book introduces readers to programming in LogiQL which is a subset of Prolog, a general purpose logic programming language associated with AI and computational linguistics. The book shows how LogiQL deals with large data sets while avoiding low-level implementation details found in other relational database languages. It also explores the application of LogiQL programming in data warehousing, data mining, data quality, business rules, and more''-- Read more... Abstract: ''This book introduces readers to programming in LogiQL which is a subset of Prolog, a general purpose logic programming language associated with AI and computational linguistics. The book shows how LogiQL deals with large data sets while avoiding low-level implementation details found in other relational database languages. It also explores the application of LogiQL programming in data warehousing, data mining, data quality, business rules, and more'' LogiQL is a new state-of-the-art programming language based on Datalog. It can be used to build applications that combine transactional, analytical, graph, probabilistic, and mathematical programming. LogiQL makes it possible to build hybrid applications that previously required multiple programming languages and databases. In this first book to cover LogiQL, the authors explain how to design, implement, and query deductive databases using this new programming language. LogiQLs declarative approach enables complex data structures and business rules to be simply specified and then automatically executed. It is especially suited to business applications requiring complex rules to be implemented efficiently, for example predictive analytics and supply chain optimization. Suitable for both novices and experienced developers, the book is written in easy-to-understand language. It includes many examples and exercises throughout to illustrate the main concepts and consolidate understanding.
