"RDF database systems is a cutting-edge guide that distills everything you need to know to effectively use or design an RDF database. This book starts with the basics of linked open data and covers the most recent research, practice, and technologies to help you leverage semantic technology. With an approach that combines technical detail with theoretical background, this book shows how to design and develop semantic web applications, data models, indexing and query processing solutions."

"This book learn to be proactive in establishing performance baselines using tools like performance monitor and extended events. You’ll learn to recognize bottlenecks and defuse them before the phone rings. You’ll learn some quick solutions too, but emphasis is on designing for performance and getting it right, and upon heading off trouble before it occurs. Delight your users. Silence that ringing phone. Put the principles and lessons from SQL Server 2012 Query Performance Tuning into practice today. Establish performance baselines and monitor against them. Troubleshoot and eliminate bottlenecks that frustrate users. Plan ahead to achieve the right level of performance."

"Penerapan dari pengolahan bahasa alami ini telah banyak dilaksanakan dengan tujuan tertentu. Salah satu tujuannya adalah aplikasi basis data yang dikembangkan oleh program ini. Pada dasarnya program ini akan mengolah bentuk dari kalimat-kalimat query dalam bahasa Indonesia dan merubahnya menjadi bentuk SQL standar. SQL standar inilah yang akan diinterpretasikan oleh suatu RDBMS (Oracle, Informix,dan sebagainya). Kelemahan utama dari pengolahan bahasa alami ini adalah keterbatasan dari semantik kalimat yang disebabkan oleh keterbatasan yang ada pada SQL ini sendiri. Suatu kalimat membutuhkan suatu bentuk tata bahasa. Bagaimanapun alaminya suatu kalimat bahasa, kalimat tersebut pasti akan mengikuti kaidah umum yang ada pada suatu struktur tata bahasa. Penyusunan dari tata bahasa inilah yang merupakan hal yang terpenting dalam pengolahan bahasa alami. Tata bahasa semantik adalah tata bahasa yang disusun bukan berdasarkan pada sintak kalimat, tetapi disusun berdasarkan pada arti kata penyusun kalimat. Kebutuhan akan pembentukan tata bahasa semantic ini membutuhkan penelitian tersendiri untuk memperoleh struktur umum dari kalimat-kalimat yang akan digunakan oleh pemakai."

"This book present a scalable framework that relies on data summaries that are distributed and maintained as multidimensional routing indices. Different types of data summaries enable efficient processing of a variety of advanced query operators."

"The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between Grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. This, the fifth issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains nine selected full-length papers, focusing on the topics of query processing, information extraction, management of dataspaces and contents, and mobile applications."

"Topics covered include skyline queries, probabilistic logics and reasoning, theory of conceptual modeling, prediction in networks of moving objects, validation of XML integrity constraints, management of loosely structured multi-dimensional data, data discovery in the presence of annotations, and quality ranking for Web articles."
