SQL on Hadoop für praktikables BI auf Big Datainovex GmbH
Nachdem in den letzten Jahren NoSQL ein beherrschendes Thema im Kontext von Big Data war, gewinnt SQL als Anfragesprache wieder große Bedeutung im Hadoop-Umfeld. Dabei steht mit Hive ein SQL-Dialekt zur Verfügung, mit dem zwar leicht Batch-orientierte ETL-Strecken für Hadoop gebaut werden können, der aber bisher für interaktive Analysen nicht geeignet war Mit Impala, Presto, Spark SQL und dem Stinger-Projekt ändert sich das nun rapide. Schnelle verteilte Query Engines erlauben interaktive analytische Anfragen auf großen Datenmengen. Dazu kommen neue Speicherformate wie Parquet und ORC, die effizientere Repräsentation und schnelleren Zugriff versprechen. In dieser Session geben wir einen Überblick über Stärken und Schwächen der verschiedenen Ansätze und berichten praktische Erfahrungen aus Projekten zur Integration mit Open Source und kommerziellen BI-Lösungen.
Speaker: Hans-Peter Zorn und Dominik Benz, inovex GmbH, Karlsruhe

Fusion der Welten: Hadoop als DWH-Backend bei ProSiebeninovex GmbH
Klassische BI-Tools integrieren mit Big Data-Technologien, wie geht das am geschicktesten?
Wir stellen ein Projekt bei ProSiebenSat.1 vor, in dem wir klassische open-source ETL-Tools zur DWH-Bewirtschaftung mit Hadoop-Werkzeugen mischen. Das relationale DWH wird mit Hadoop-aggregierten Daten aus heterogenen Quellen befüllt.
Wie das alles funktioniert und welche Rolle Hadoop, das DWH, Pig und Hive dabei spielen, möchten wir in diesem Vortrag erklären.
Die Oracle Datenbank und Apache Hadoop
DOAG -Big Data für Oracle Entwickler: Zweitagesveranstaltung mit Hands-On - 25.09.2014 in Köln
DOAG 2014 -Die größte Anwenderkonferenz rund um alle Oracle Themen, vom 18.11.2014 - 20.11.2014 in Nürnberg
Die Oracle Datenbank in die Welt von Hadoop und NoSQL integrieren
Wie lassen sich die beiden Welten, Oracle RDBMS und der NoSQL Ansatz sinnvoll für die Archivierung und das Datensammeln einsetzen?
Ziel des Vortrags ist es aufzuzeigen, wie die Kombinationen aus den Vorteilen der beiden Welten für die Analyse und Archivierung von Daten eingesetzt werden kann.
Hadoop, mit einer entsprechen Container Datenbank Lösung, eignet sich gut, um im ersten Schritt Daten zu sammeln und/oder im letzten Schritt Daten zu archivieren.
Die eigentliche Oracle RDBMS Datenbank kann dabei schnell und schlank gehalten werden, um Hardware und damit Lizenzkosten einzusparen.
Es werden Architekturansätze aufgezeigt, wie die Integration der Oracle RDBMS und NoSQL Datenbank in das Hadoop Ökosystem dabei erfolgen kann.
Mit den kostenpflichtigen Adaptern der Oracle RDBMS lässt sich zwar einfacher eine tiefe Integration mit Hadoop erreichen, aber auch mit den freien Lösungen kann bereits eine umfangreiche Lösung implementiert werden.
OSMC 2011 | Monitoring "wer kennt wen" mit free and open source software by J...NETWAYS
Die Überwachung einer der größten deutschen Communitys hält eine Reihe von Herausforderungen und Problemen bereit. Aus einer Struktur heraus gewachsen, war das alte Monitoringsystem unterwegs in eine Sackgasse. Diesen Prozess galt es aufzuhalten und das vertraute System mit mehr Features auszustatten, es skalierbar und robust zu machen. Der Vortrag behandelt die besondere Entstehungsgeschichte und welche Möglichkeiten Grocksta, ein verteiltes, asynchrones Monitoring-, Graphing- und Aggregations-System, bietet."
Der Vortrag beschreibt die Architektur eines serviceorientierten, modular erweiterbaren DWH-Modells und dem dazu gehörigen Berichtswesens. Er soll außerdem zeigen, wie ein solches Modell in ein bereits existierendes, stark heterogenes Umfeld eingebunden werden kann.
Die verschiedenen Schichten des DWH-Modells sowie die Einbindung in das Umfeld werden dabei detailliert beschrieben. Auf die Vor- und Nachteile der verschiedenen Modellierungsmöglichkeiten (3NF, Stern, Cube), sowie Aspekte der zukünftigen Erweiterung und Veränderung wird ebenfalls eingegangen. Eine kurze Übersicht über Tuning und Sicherheitsaspekte beendet den ersten Teil.
Der zweite Teil besteht aus einer Übersicht über die Einbindung des Berichtswesens in die Gesamtarchitektur. Verschiedene Ansatzmöglichkeiten für die Bedienung der Anforderungen verschiedener Nutzergruppen werden erarbeitet. Zuletzt werden Ideen zur Konsolidierung und Ablösung eines stark zerklüfteten, sich widersprechenden Berichtswesens gegeben.
Der Vortrag soll damit DWH-Architekten Möglichkeiten aufzeigen, wie man ein DWH zukunftssicher und flexibel modellieren und in ein heterogenes Umfeld einbetten kann. OPITZ CONSULTING Berater Arno Tigges hielt diesen Vortrag am 29.06.2010 bei der DOAG SIG BI/DWH in Köln.
Analytics meets Big Data – R/Python auf der Hadoop/Spark-PlattformRising Media Ltd.
Big Data verändert nicht nur die Unternehmens-IT fundamental, sondern auch die Arbeit des Analysten. Die klassischen Analysten sehen sich im Zuge des Wandels zu einer datengetriebenen Unternehmenskultur mit neuen Anforderungen und ungewohnten technologischen Plattformen konfrontiert. Sie müssen als Data Scientist fachliche Fragestellungen unter dem Aspekt der Big Data-Technologien umsetzen, visualisieren und aus den Daten Werte generieren. Anhand eines konkreten Use Cases, der Programmierung eines Recommender-Systems, zeigen wir Ansätze, wie sich die gewohnten Vorgehensweisen und Werkzeuge eines Analysten (namentlich R und Python) mit einer Big Data-Technologie (Spark) kombinieren lassen. Ziel ist es, dem Analysten den Einstieg in die Big Data-Welt zu erleichtern. Wir demonstrieren die Arbeit mit diesem Toolset an anschaulichen Beispielen in einem interaktiven Workshop-Format und laden zur Diskussion und Nachahmung dieser Vorgehensweise ein. Der Workshop richtet sich an Teilnehmer mit Grundkenntnissen aus den Bereichen analytische Methoden und Machine Learning sowie R oder Python. Der Workshop wird auf der Spark-Plattform durchgeführt. Zu Spark werden keine Kenntnisse vorausgesetzt.
