Queries not running fast enough? Wondering about the in-memory database features in 2014? Tired of phone calls from frustrated users? Grant Fritchey’s book SQL Server Query Performance Tuning is the answer to your SQL Server query performance problems. The book is revised to cover the very latest in performance optimization features and techniques, especially including the newly-added, in-memory database features formerly known under the code name Project Hekaton. This book provides the tools you need to approach your queries with performance in mind. SQL Server Query Performance Tuning leads you through understanding the causes of poor performance, how to identify them, and how to fix them. You’ll 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 Query Performance Tuning into practice today.

This book is a deep dive into perhaps the single-most important facet of good performance: indexes, and how to best use them. The book begins in the shallow waters with explanations of the types of indexes and how they are stored in databases. Moving deeper into the topic, and further into the book, you will look at the statistics that are accumulated both by indexes and on indexes. Youll better understand what indexes are doing in the database and what can be done to mitigate and improve their effect on performance. The final destination is a guided tour through a number of real life scenarios showing approaches you can take to investigate, mitigate, and improve the performance of your database. Defines the types of indexes and their implementation options Provides use cases and common patterns in applying indexing Describes and explain the index metadata and statistics Provides a framework of strategies and approaches for indexing databases Jason Strate is a database architect and administrator with more than 15 years of experience.

Doktorarbeit / Dissertation aus dem Jahr 2008 im Fachbereich Informatik - Wirtschaftsinformatik, Note: magna cum laude, Eberhard-Karls-Universität Tübingen (Wirtschaftswissenschaftlichen Fakultät), Sprache: Deutsch, Abstract: Die wissenschaftliche Auseinandersetzung mit Kennzahlen- und Informationssystemen sowie ihre Umsetzung in der Praxis unterlagen in den letzten Jahrzehnten in der Betriebswirtschaftslehre im Allgemeinen und innerhalb der Wirtschaftsinformatik sowie des Controllings im Speziellen wechselnder Aufmerksamkeit. Über den Zeitverlauf hinweg war zu beobachten, dass die den Kennzahlen- und Informationssystemen zugrunde liegenden betriebswirtschaftlichen Konzepte teils verworfen, häufig jedoch verbessert und weiterentwickelt wurden. Diese konzeptionellen Fortschritte führten - verstärkt durch innovative Entwicklungen unter Nutzung der informations- und kommunikationstechnologischen Potenziale - zum heute weitverbreiteten Einsatz. Die große Bedeutung der Auseinandersetzung mit dieser Art von Systemen für die Wissenschaft zeigt sich daran, dass die nachfolgende Arbeit dem ersten von fünf für die Wirtschaftsinformatik priorisierten Forschungszielen, der Schaffung eines verbesserten Wissens über die Beherrschung von Komplexität in Informations- und Kommunikationssystemen zugeordnet werden kann. Eine Begründung der bis heute andauernden und mehr und mehr an Bedeutung gewinnenden Beschäftigung mit Kennzahlen- und Informationssystemen kann in der Wahrnehmung der hohen Relevanz von Information und ihrer Einstufung als Wirtschaftsgut, Produktions- und Wettbewerbsfaktor in der gegenwärtigen Informationsgesellschaft gefunden werden. Aufgrund der Erkenntnis, dass das effektive und effiziente Management der Informationen in Zeiten schneller wirtschaftlicher, technischer, politischer und sozialer Änderungen einen entscheidenden Faktor für eine erfolgreiche Unternehmensentwicklung darstellt, muss sich das Informationsmanagement im Unternehmen neuen Herausforderungen stellen. Nur so kann es seiner zugewiesenen Aufgabe nachkommen, einen Beitrag zur Erreichung der Unternehmensziele zu leisten. [...] Zur Erfüllung der steigenden Anforderungen und zur Bewältigung der Aufgabenvielfalt durch den Anwender, auch unter Zeitdruck, werden in Unternehmen System(e) zur Beschaffung, Verarbeitung, Übertragung, Speicherung und/oder Bereitstellung von Informationen eingesetzt. Diese bestehen im weiteren Sinne aus den Komponenten Organisation, Mensch und Technologie und verfolgen das Ziel, den Entscheidungsträger mit relevanten Informationen so zu versorgen, dass er in die Lage versetzt wird, die zur Erreichung der Unternehmensziele richtigen Entscheidungen treffen zu können ...

Presents a new, effective methodology in software size measurement Software size measurement is an extremely important and highly specialized aspect of the software life cycle. It is used for determining the effort and cost estimations for project planning purposes of a software projects execution, and/or for other costing, charging, and productivity analysis purposes. Many software projects exceed their allocated budget limits because the methodologies currently available lack accuracy. The new software size measurement methodology presented in this book offers a complete procedure that overcomes the deficiencies of the current methodologies, allowing businesses to estimate the size and required effort correctly for all their software projects developed in high level languages. The Functional Software Size Measurement Methodology with Effort Estimation and Performance Indication (FSSM) allows for projects to be completed within the defined budget limits by obtaining accurate estimations. The methodology provides comprehensive and precise measurements of the complete software whereby factual software size determination, development effort estimation, and performance indications are obtained. The approach is elaborate, effective and accurate for software size measurement and development effort estimation, avoiding inaccurate project planning of software projects. Key features: Pinpoints one of the major, originating root causes of erroneous planning by disclosing hidden errors made in software size measurement, and consequently in effort estimates and project planning All the major relevant and important aspects of software size measurement are taken into consideration and clearly presented to the reader Functional Software Size Measurement Methodology with Effort Estimation and Performance Indication is a vital reference for software professionals and Master level students in software engineering.
