Ein in Zukunft an Bedeutung stark zunehmender Bereich der Computernetze ist die automatisierte mobile Datenerfassung mittels Sensorknoten, welche batteriebetrieben und völlig autark in einem drahtlosen Sensornetz zu verschiedenen Zwecken eingesetzt werden können. Das Fraunhofer Institut für Integrierte Schaltungen arbeitet selbst an einer proprietären Implementierung solcher Sensorknoten und der dazugehörigen Software. Wie in den meisten Bereichen der Informatik steigt mit zunehmenden Möglichkeiten die Komplexität der Software auf den Geräten, was zwangsläufig dazu führt, dass in der Software verstärkt Fehler auftreten können. Im Rahmen dieser Diplomarbeit wurde ein Konzept und eine Implementierung eines Bootloaders entwickelt, welcher eine Aktualisierung der Software dieser Sensorknoten ermöglicht. Dabei wurde auf die Anforderung, größtmögliche Ausfallsicherheit beim Installationsvorgang eines Firmware-Images zu gewährleisten, eingegangen. Das Konzept sieht vor, dass verschiedene Sicherungsmechanismen einen unbenutzbaren Sensorknoten verhindern sollen und mehrere Firmware-Images auf dem Sensorknoten verwaltet werden können. Die prototypische Implementierung realisiert die Teile des Konzepts, welche ohne ohne Kenntnis des endgültigen Aktualisierungsmechanismus (in Bezug auf Teilaktualisierungsverfahren und Übertragungsmethodik) implementiert werden konnten.

Das Internet of Things ist mittlerweile gar nicht mehr so neu, Zeit also für einen Blick zurück und für einen aktuellen Stand der Dinge. In diesem shortcut wird nach einem kurzen Rückblick besonders auf das Thema Microcontroller eingegangen. Dabei nimmt der Autor zuerst den 16-Bit-Microcontroller von Texas Instruments (TI MSP430) unter Eclipse in Betrieb. Anschließend widmet er sich der STM32-Microcontrollerfamilie und bespricht die Grundlagen der Embedded-Programmierung; auch RTOS wird miteinbezogen. Abschließend befasst sich der shortcut mit der Umsetzung vollgrafischer User Interfaces. Tam Hanna befasst sich seit der Zeit des Palm IIIc mit der Programmierung und Anwendung von Handcomputern. Er entwickelt Programme für diverse Plattformen, betreibt Onlinenewsdienste zum Thema und steht unter email@example.com für Fragen, Trainings und Vorträge gern zur Verfügung.
Performance problems are rarely problems per se. They are more often crises during which youre pressured for results by a manager standing outside your cubicle while your phone rings with queries from the help desk. You wont have the time for a leisurely perusal of the manuals, nor to lean back and read a book on theory. What you need in that situation is a book of solutions, and solutions are precisely what Oracle Database 12c Performance Tuning Recipes delivers. Oracle Database 12c Performance Tuning Recipes is a ready reference for database administrators in need of immediate help with performance issues relating to Oracle Database. The book takes an example-based approach, wherein each chapter covers a specific problem domain. Within each chapter are recipes, showing by example how to perform common tasks in that chapters domain. Solutions in the recipes are backed by clear explanations of background and theory from the author team. Whatever the task, if its performance-related, youll probably find a recipe and a solution in this book. Provides proven solutions to real-life Oracle performance problems Offers relevant background and theory to support each solution Gets straight to the point for when youre under pressure for results Sam R.

Speed up the execution of important database queries by making good choices about which indexes to create. Choose correct index types for different scenarios. Avoid indexing pitfalls that can actually have indexes hurting performance rather than helping. Maintain indexes so as to provide consistent and predictable query response over the lifetime of an application. Expert Oracle Indexing and Access Paths is about the one database structure at the heart of almost all performance concerns: the index. Database system performance is one of the top concerns in information technology today. Administrators struggle to keep up with the explosion of access and activity driven by the proliferation of computing into everything from phones to tablets to PCs in our increasingly connected world. At the heart of any good-performing database lies a sound indexing strategy that makes appropriate use of indexing, and especially of the vendor-specific indexing features on offer. Few databases fully exploit the wealth of data access mechanisms provided by Oracle. Expert Oracle Indexing and Access Paths helps by bringing together information on indexing and how to use it into one blissfully short volume that you can read quickly and have at your fingertips for reference. Learn the different types of indexes available and when each is best applied. Recognize when queries arent using indexes as you intend. Manage your indexing for maximum performance. Confidently use the In Memory column store feature as an alternate access path to improve performance. Let Expert Indexing in Oracle Database 12c be your guide to deep mastery of the most fundamental performance optimization structure in Oracle Database. Explains how indexes help performance, and sometimes hinder it too Demystifies the various index choices so that you can chose rightly Describes the database administration chores associated with indexes Demonstrates the use of the In Memory column store as an alternate access path to the data What You Will Learn Create an overall indexing strategy to guide your decisions Choose the correct indexing mechanisms for your applications Manage and maintain indices to avoid degradation and preserve efficiency Take better advantage of underused index types such as index-organized tables Choose the appropriate columns to index, with confidence Blend partitioning and materialized views into your indexing strategy Who This Book Is For Expert Oracle Indexing and Access Paths is for all levels of database administrators and application developers who are struggling with the database performance and scalability challenge. Any database administrator involved with indexing, which is any database administrator period, will appreciate the wealth of advice packed into this gem of a book.

SQL for Smarties was hailed as the first book devoted explicitly to the advanced techniques needed to transform an experienced SQL programmer into an expert. Now, 20 years later and in its fifth edition, this classic reference still reigns supreme as the only book written by a SQL master that teaches programmers and practitioners to become SQL masters themselves! These are not just tips and techniques; also offered are the best solutions to old and new challenges. Joe Celko conveys the way you need to think in order to get the most out of SQL programming efforts for both correctness and performance. New to the fifth edition, Joe features new examples to reflect the ANSI/ISO Standards so anyone can use it. He also updates data element names to meet new ISO-11179 rules with the same experience-based teaching style that made the previous editions the classics they are today. You will learn new ways to write common queries, such as finding coverings, partitions, runs in data, auctions and inventory, relational divisions and so forth. SQL for Smarties explains some of the principles of SQL programming as well as the code. A new chapter discusses design flaws in DDL, such as attribute splitting, non-normal forum redundancies and tibbling. There is a look at the traditional acid versus base transaction models, now popular in NoSQL products. Youll learn about computed columns and the DEFERRABLE options in constraints. An overview of the bi-temporal model is new to this edition and there is a longer discussion about descriptive statistic aggregate functions. The book finishes with an overview of SQL/PSM that is applicable to proprietary 4GL vendor extensions. New to the 5 th Edition: Downloadable data sets, code samples, and vendor-specific implementations! Overview of the bitemporal model Extended coverage of descriptive statistic aggregate functions New chapter covers flaws in DDL Examination of traditional acid versus base transaction models Reorganized to help you navigate related topics with ease Expert advice from a noted SQL authority and award-winning columnist Joe Celko, who served on the ANSI SQL standards committee for over a decade Teaches scores of advanced techniques that can be used with any product, in any SQL environment, whether it is SQL 92 or SQL 2011 Offers tips for working around deficiencies and gives insight into real-world challenges Joe Celko served 10 years on ANSI/ISO SQL Standards Committee and contributed to the SQL-89 and SQL-92 Standards.
