Projektarbeit aus dem Jahr 2017 im Fachbereich Informatik - Programmierung, Note: 1,7, FOM Hochschule für Oekonomie & Management gemeinnützige GmbH, Stuttgart, Sprache: Deutsch, Abstract: Das Ziel der vorliegenden Projektarbeit ist es, dem Leser einen Überblick über die SAP HANA-Datenbank sowie die In-Memory-Plattform als Ganzes und deren wesentliche Merkmale, Bestandteile und Funktionen zu verschaffen. Dabei soll auch einem Leser, der keinen Bezug zu Datenbanktechnologien hat, anschaulich gemacht werden, wie eine SAP HANA-Datenbank funktioniert, welchem Datenbankmodell es zugrunde liegt und welche Voraussetzungen das System erfüllen muss, damit die SAP HANA-Datenbank in Betrieb genommen werden kann.Mit der Einführung von Personal Computer ist das digitale Datenaufkommen rasant gestiegen, seien es nun Unternehmensdaten oder Daten, die ihren Ursprung im Internet haben. Daher stehen die Unternehmen vor der großen Herausforderung, die eintreffenden großen Datenmengen effizient zu verarbeiten. Für die die Bewältigung dieser Herausforderung steht der Begriff Big Data. Die klassischen rationalen Datenbanken sind nicht mehr in der Lage, eine so große Datenmenge in Echtzeit zu verarbeiten. Daher müssen andere Ansätze für eine Datenverarbeitung erforscht werden. Durch den Preisverfall für Arbeitsspeicher wurde es für die Unternehmen finanziell möglich, die Server mit einer großen Arbeitsspeichergröße auszustatten, sodass der Datenzugriff auf die Daten nicht mehr über Festplatten stattfinden muss, sondern direkt aus dem Arbeitsspeicher gelesen werden kann. Diese Art der Datenhaltung wird auch In-Memory genannt. Diesen Trend hat auch der weltweit führende Anbieter für Standardsoftware, die SAP, erkannt und eine In-Memory-Datenbank namens SAP HANA entwickelt. Da es eine relativ neue Technologie ist, ist es nicht jedem bekannt, wie sie funktioniert und welche technischen Grundlagen hinter dieser Technologie verborgen sind.Um den Überblick über SAP HANA In-Memory-Plattform besser darzustellen, ist der Aufbau dieser Projektarbeit in zwei große Teilbereiche aufgeteilt. Zum Verständnis darüber, auf welchen allgemeinen Datenbankmodellen die In-Memory-Technologie und die SAP HANA-Datenbank aufbauen, wird in den ersten Kapiteln der Fokus auf allgemeine Datenbanktechnologien gelegt. Hier werden zum einen die technologischen Grundsätze, aber auch die Geschichte der SAP, das Wie und Warum dargelegt. Der zweite Teil der Arbeit beschreibt die In-Memory-Technologie, die technologischen Wegbereiter für diese sowie den Aufbau einer In-Memory-Datenbank.

Recent spectacular achievements in wireless, mobile, and sensor networks have dramatically changed our lives in many ways. However, the rapid evolution of wireless systems not only promises increased functionality, reliability, availability, and security, as well as putting a wide variety of new services at the users' disposal ? it also creates a number of design challenges that our research community is now facing. Scientists and engineers need to come up with, and promptly implement, novel wireless network architectures, while system operators and planners rethink their business models and attend to the growing expectations of their customer base. To provide a suitable forum for discussion between researchers, practitioners, and industry representatives interested in new developments in the respective research area, IFIP WG 6. 8 launched three separate series of conferences: MWCN (Mobile and Wireless Communications Networks), PWC (Personal Wireless Communications), and WSAN (Wireless Sensor and Actors Networks). In 2008, MWCN and PWC were merged into the IFIP Wireless and Mobile Networking Conference (WMNC 2008), held in Toulouse, France, from September 30 to October 2, 2008. MWNC 2008 and PWC 2008 topics were subsequently revised with a view to covering the whole spectrum of hot issues in wireless and mobile networking. As a result, IFIP WG 6. 8 decided to add WSAN as another WMNC track.

Diese Einführung in die Oracle Datenbankadministration bietet einen schnellen Einstieg in die Installation, den Betrieb und das Backup einer Oracle 19c Datenbank. Dabei liegt der Fokus auf Datenbanken, die nicht in der Cloud, sondern auf eigenen Servern (on premise) betrieben werden. Es wird gezeigt, wie eine Einzelinstanz als herkömmliche Non-CDB oder als Multitenant-Containerdatenbank aufgesetzt werden kann und wie beim Aufbau eines Real Application Clusters vorgegangen werden muss. Erläutert werden die Komponenten, aus denen eine Datenbank und ihre Instanz bestehen, die Bedeutung von Speicherbereichen und Schemaobjekten. Die Besonderheiten einer Containerdatenbank gegenüber der älteren Non-CDB Architektur werden beschrieben. Hinweise werden gegeben, welche Initialisierungsparameter besser auf ihren Vorgabewerten belassen und welche unbedingt angepasst werden sollten. Besonderen Raum wurde dem Thema Backup und Recovery eingeräumt. Es wird gezeigt, welche Befehle in einem Sicherungsskript nicht fehlen sollten und wie Schäden an einer Oracle Datenbank erkannt und repariert werden können. Nach der Lektüre sollten sich Leserinnen und Leser nicht mehr orientierungslos gegenüber einer Oracle Datenbank fühlen.  Der InhaltEinführung (Geschichte und Versionsentwicklung von Oracle)Installation (Editionen, Einzelinstanz, RAC, Non-CDB, Containerdatenbank)Datenbank Grundlagen (Aufbau von Datenbank und Instanz, Schemaobjekte, Containerarchitektur)Backup und Recovery (Aufsetzen einer soliden Datenbanksicherung, Wiederherstellungsszenarien)Die ZielgruppenNeueinsteiger in das Thema Oracle DatenbankadministrationWiederkehrer, deren Oracle Wissensstand vor einigen Versionen auf Eis gelegt wurdeMySQL-Administratoren, die neu mit der Betreuung von Oracle Datenbanken beauftragt worden sindDer AutorThorsten Grebeberät und betreut seit über 15 Jahren Organisationen aus Wirtschaft und öffentlichem Dienst zur Oracle Datenbank.
