While it is easy to learn and understand the Cypher declarative language for querying graph databases, it can be very difficult to master it. As graph databases are becoming more mainstream, there is a dearth of content and guidance for developers to leverage database capabilities fully. This book fills the information gap by describing graph traversal patterns in a simple and readable way.This book provides a guided tour of Cypher from understanding the syntax, building a graph data model, and loading the data into graphs to building queries and profiling the queries for best performance. It introduces APOC utilities that can augment Cypher queries to build complex queries. You’ll also be introduced to visualization tools such as Bloom to get the most out of the graph when presenting the results to the end users.After having worked through this book, you’ll have become a seasoned Cypher query developer with a good understanding of the query language and how to use it for the best performance.

Analiza danych z Hadoopem — i wszystko staje się prostsze! Podstawy Hadoopa i model MapReduce Praca z Hadoopem, budowa klastra i zarządzanie platformą Dodatki zwiększające funkcjonalność Hadoopa Platforma Apache Hadoop to jedno z zaawansowanych narzędzi informatycznych. Dzięki niej można przeprowadzać różne operacje na dużych ilościach danych i znacznie skrócić czas wykonywania tych działań. Wszędzie tam, gdzie potrzebne jest szybkie sortowanie, obliczanie i archiwizowanie danych — np. w dużych międzynarodowych sklepach internetowych, serwisach społecznościowych lub wyszukiwarkach, takich jak Amazon, Facebook, Yahoo!, Apache Hadoop sprawdza się znakomicie. Jeśli potrzebne Ci narzędzie do poważnej analizy dużych zbiorów danych, nie znajdziesz lepszego rozwiązania! Tę książkę napisał wytrawny znawca i współtwórca Hadoopa. Przedstawia w niej wszystkie istotne mechanizmy działania platformy i pokazuje, jak efektywnie jej używać. Dowiesz się stąd, do czego służą model MapReduce oraz systemy HDFS i YARN. Nauczysz się budować aplikacje oraz klastry. Poznasz dwa formaty danych, a także wykorzystasz narzędzia do ich pobierania i transferu. Sprawdzisz, jak wysokopoziomowe narzędzia do przetwarzania danych współdziałają z Hadoopem. Zorientujesz się, jak działa rozproszona baza danych i jak zarządzać konfiguracją w środowisku rozproszonym. Przeczytasz również o nowinkach w Hadoopie 2 i prześledzisz studia przypadków ilustrujące rolę Hadoopa w systemach służby zdrowia i przy przetwarzaniu danych o genomie.
