This book introduces the problems facing Internet of Things developers and explores current technologies and techniques to help you manage, mine, and make sense of the data being collected through the use of the worlds most popular database on the Internet - MySQL. The IoT is poised to change how we interact with and perceive the world around us, and the possibilities are nearly boundless. As more and more connected devices generate data, we will need to solve the problem of how to collect, store, and make sense of IoT data by leveraging the power of database systems. The book begins with an introduction of the MySQL database system and storage of sensor data. Detailed instructions and examples are provided to show how to add database nodes to IoT solutions including how to leverage MySQL high availability, including examples of how to protect data from node outages using advanced features of MySQL. The book closes with a comparison of raw and transformed data showing how transformed data can improve understandability and help you cut through a clutter of superfluous data toward the goal of mining nuggets of useful knowledge. In this book, youll learn to: Understand the crisis of vast volumes of data from connected devices Transform data to improve reporting and reduce storage volume Store and aggregate your IoT data across multiple database servers Build localized, low-cost MySQL database servers using small and inexpensive computers Connect Arduino boards and other devices directly to MySQL database servers Build high availability MySQL solutions among low-power computing devices Charles Bell conducts research in emerging technologies. He is a member of the Oracle MySQL Development team and is the team lead for the MySQL Utilities team. He lives in a small town in rural Virginia with his loving wife. He received his Doctor of Philosophy in Engineering from Virginia Commonwealth University in 2005. Dr. Bell is an expert in the database field and has extensive knowledge and experience in software development and systems engineering.

Walk away from old-fashioned and cumbersome query approaches and answer your business intelligence questions through simple and powerful queries built on common table expressions (CTEs) and window functions. These new features in MariaDB and MySQL help you to write queries without having to wade through a quagmire of brittle self-joins and other crazy techniques from the past. Your queries will generate correct results, be more readable and less brittle in the face of unexpected data, and youll be able to adapt them quickly in the face of changing business requirements. MariaDB and MySQL Common Table Expressions and Window Functions Revealed introduces and explains CTEs and window functions, newly available in MariaDB 10.2 and MySQL 8.0, and helps you understand why and how every MariaDB and MySQL database programmer should learn and apply these features in their daily work. CTEs and especially window functions enable easy solutions to many query challenges that in prior releases have been difficult and sometimes impossible to surmount. Mastering these features opens the door to query solutions that are more robust, execute faster, and are easier to maintain over time than prior solutions using older techniques. The book: Takes you step-by-step through the workings of common table expressions and window functions Provides easy-to-follow examples of the new syntax Helps you answer business questions faster and easier than ever What Youll Learn Answer business questions using simple queries that dont break in the face of unexpected data Avoid writing queries that are a difficult-to-maintain quagmire of self-joins and nested subqueries Recognize situations that call for window functions, and learn when to use these features Reduce the need for performance-robbing self-joins Simplify and speed the execution of analytical queries Create queries that finish in seconds instead of hours Who This Book Is For Database administrators and application developers who want to quickly get up to speed on important features in MariaDB and MySQL for writing business intelligence queries. Any developer writing SQL against MariaDB and MySQL databases will benefit tremendously from the knowledge and techniques this book provides. Daniel Bartholomew has been using Linux since 1997 and databases since 1998. In addition to this book, he has written MariaDB Cookbook and Getting Started with MariaDB (1st and 2nd editions), and dozens of articles for various magazines, including The Linux Journal, Linux Pro, Ubuntu User, and Tux.

Bachelorarbeit aus dem Jahr 2010 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1, Ferdinand Porsche FernFH, Sprache: Deutsch, Abstract: Datenbanken sind aus einem Unternehmen nicht mehr wegzudenken. In beinahe allen Gescha?ftsbereichen werden Daten zur vielfa?ltigen Weiterverwendung gespeichert. Daher stellt die Auswahl einer passenden Datenbank eine essentielle Frage dar, da die Anforderungen, die vom Unternehmen an ein Datenbanksystem gestellt werden, sich immer komplexer gestalten. Zusa?tzlich weisen die unterschiedlichen Datenbanksysteme umfangreiche Featurelisten bei unterschiedlicher Performance und Skalierung auf, was die Auswahl erschwert, da ein gro?ßeres Know-How seitens den Entscheidungstra?gern vorausgesetzt wird. In dieser Arbeit werden vier Datenbanken (Microsoft SQL Server, MySQL, Oracle und PostgreSQL) einer Analyse im Hinblick auf die oben genannten Faktoren unterzogen. Diese vollzieht sich in zwei Schritten. Im ersten Schritt wird auf den Hintergrund der Datenbank eingegangen; Supportleistungen, Lizenzierung sowie Administrationswerkzeuge werden eingehend behandelt, gegenu?bergestellt und kritisch gepru?ft. Im zweiten Schritt werden Datenbankfeatures erhoben und die Funktionalita?t dieser Anforderungen mithilfe verschiedener Testunternehmensdatenbanken tatsa?chlichen Anforderungen gegenu?bergestellt. Eine Entscheidungsmatrix fasst die Ergebnisse objektiv zusammen, die als inhaltliche und wertfreie Entscheidungsgrundlage gesehen werden ko?nnen. contact.hpzach.at

This book is a complete guide to setting up and maintaining maintenance plans for SQL Server Database Administrators. Maintenance plans too often consist of a backup task and thats it, but there is so much more that can and must be done to ensure the integrity of your most important company resource - the data you are tasked to manage and safeguard. This book walks even the newest of users through creating a powerful, automated maintenance plan. Automate your job using SQL Server Agent to leverage the power of Maintenance Plans to deliver real, proactive solutions to common issues. Schedule common tasks such as backups and index rebuilds to run automatically, and get early-warning notifications of impending problems relating to resource usage and query performance. By the time your boss knows to call you about a problem, youll have already called him to describe your solution. The large majority of books never really cover the topic of inheriting a database server with multiple live databases; the common thread is that the databases will be created and maintained by the reader forever and ever. In the real world, that scenario rarely happens. Practical Maintenance Plans in SQL Server covers that scenario and provides you with the knowledge and tools needed to get comfortable writing your own maintenance plans for any SQL Server database, whether created by you or inherited. Shows the different tasks that can be run in a maintenance plan. Explains how and why those tasks can be implemented. Provides a roadmap to creating your own custom maintenance plan.
