The book is organized as follows. In the beginning of this book (chapters 1 through 6), you learn how to build a data warehouse, for example, defining the architecture, understanding the methodology, gathering the requirements, designing the data models, and creating the databases. Then in chapters 7 through 10, you learn how to populate the data warehouse, for example, extracting from source systems, loading the data stores, maintaining data quality, and utilizing the metadata. After you populate the data warehouse, in chapters 11 through 15, you explore how to present data to users using reports and multidimensional databases and how to use the data in the data warehouse for business intelligence, customer relationship management, and other purposes. Chapters 16 and 17 wrap up the book: After you have built your data warehouse, before it can be released to production, you need to test it thoroughly. After your application is in production, you need to understand how to administer data warehouse operation. |
| ssis performance tuning interview questions: Geographic Citizen Science Design Artemis Skarlatidou, Muki Haklay, 2021-02-04 Little did Isaac Newton, Charles Darwin and other ‘gentlemen scientists’ know, when they were making their scientific discoveries, that some centuries later they would inspire a new field of scientific practice and innovation, called citizen science. The current growth and availability of citizen science projects and relevant applications to support citizen involvement is massive; every citizen has an opportunity to become a scientist and contribute to a scientific discipline, without having any professional qualifications. With geographic interfaces being the common approach to support collection, analysis and dissemination of data contributed by participants, ‘geographic citizen science’ is being approached from different angles. Geographic Citizen Science Design takes an anthropological and Human-Computer Interaction (HCI) stance to provide the theoretical and methodological foundations to support the design, development and evaluation of citizen science projects and their user-friendly applications. Through a careful selection of case studies in the urban and non-urban contexts of the Global North and South, the chapters provide insights into the design and interaction barriers, as well as on the lessons learned from the engagement of a diverse set of participants; for example, literate and non-literate people with a range of technical skills, and with different cultural backgrounds. Looking at the field through the lenses of specific case studies, the book captures the current state of the art in research and development of geographic citizen science and provides critical insight to inform technological innovation and future research in this area. |

| ssis performance tuning interview questions: SQL Server Interview Questions and Answers Vinod Kumar, Pinal Dave, 2021-03 As representatives from the IT community, all of us have had our own experiences of attending interviews - clearing or close to clearing and sometimes with tons of questions and doubts failing miserably. These stories are in the most pleasant or not so pleasant memories of our mind and we will assure you this book will kindle those memories for sure. We have taken tons of interviews and most of the interviews are not revolving around how deep technical and internals you know about the subject - but it revolves around how good you are with the basics.To clear an interview, one doesn't need to know inside-out of a subject, and subjects like SQL Server so vast that every single day we learn something new with this product, and even a complete lifetime will fly off if we keep doing this. Again, the various roles one can get into for products like SQL Server are from Database Developer, Database Modelers, Database Architect, Database Administrator and many more. Hence, this book is geared towards demystifying and a refresher for memories on the fundamentals which sometimes are the most important things to clear any type of interview for any role. Some of the concepts discussed are generic and are not tied to any specific version of SQL Server, but most of it the new features introduced with SQL Server have been included in this book.This book is not a shortcut or a sure to crack interview guide but this book gets you prepared in an organized manner. Let us also assure you this is neither a completely comprehensive guide but surely is a great starter nevertheless. Use this to guide you and be mentally prepared for the big day. When faced with this big day, we get overwhelmed and confused about where to start our preparation. And this book is just that secret recipe in your arsenal to get geared up. Sometimes these basics will help you narrow to a solution quickly when given a scenario.Now this book's flow is Question & Answer mode from start till the end to help you grasp the concepts faster and to the point. Once you get an understanding of concepts, then if we are twisted with the concept in a scenario it becomes easy to solve them. Most companies have a typical way to do interviews which are based on the scenario as per their environment and these are just combinations of the concepts to fit their need and SLA.Though each of these chapters is bucketed for convenience we highly recommend reading each of the sections nevertheless irrespective of the roles you might be doing as each of the sections have some interesting trivia's working with SQL Server. In the industry, the role of accidental DBA's especially with SQL Server is so common. Hence if you have performed the role of DBA for a short stink and want to brush-up your fundamentals then the respective sections will be a great skim. |

| ssis performance tuning interview questions: Modeling the Interplay Between Human Behavior and the Spread of Infectious Diseases Piero Manfredi, Alberto D'Onofrio, 2013-01-03 This volume summarizes the state-of-the-art in the fast growing research area of modeling the influence of information-driven human behavior on the spread and control of infectious diseases. In particular, it features the two main and inter-related “core” topics: behavioral changes in response to global threats, for example, pandemic influenza, and the pseudo-rational opposition to vaccines. In order to make realistic predictions, modelers need to go beyond classical mathematical epidemiology to take these dynamic effects into account. With contributions from experts in this field, the book fills a void in the literature. It goes beyond classical texts, yet preserves the rationale of many of them by sticking to the underlying biology without compromising on scientific rigor. Epidemiologists, theoretical biologists, biophysicists, applied mathematicians, and PhD students will benefit from this book. However, it is also written for Public Health professionals interested in understanding models, and to advanced undergraduate students, since it only requires a working knowledge of mathematical epidemiology. |

| ssis performance tuning interview questions: Java Application Frameworks Darren Govoni, 1999-06-25 A complete guide to designing and using frameworks for Java applications. Java(TM) Application Frameworks. Application frameworks are a major leap forward in systems design and software reusability. Java has provided an enormous foundation upon which highly reusable components and applications can be built successfully. Building object-oriented systems is complex. Building highly reusable frameworks and components is even more challenging. This book substantially reduces the application frameworks' learning curve. Expert Darren Govoni follows a natural progression, from concept, to practice, to implementation. Building on examples of existing frameworks, he walks you through all the steps involved in designing frameworks, and provides guidelines on how to use frameworks within large architectures and systems. Important topics covered include: * Basic framework concepts and design techniques. * Using 8 design patterns-illustrated with UML-for framework design and implementation. * Constructing JavaBean components as the building blocks for a reusableframework . * A complete discussion of two powerful Java frameworks-Java Foundation Classes (JFC/Swing) and InfoBus-and how they adhere to the important traits found in good frameworks: proper use of abstraction through interfaces and abstract classes, substitution of application objects, extension or enhancement of key objects within the framework through abstract and default implementations. * How to manage complexity and reusability with abstracted foundations. * A complete methodology and architecture-Composite Foundation Architecture-for organizing and developing frameworks, components, and subsystems within a larger complex system. * Key considerations for developing frameworks within distributed architectures, including data access, GUIs, business objects, and distributed objects using JDBC, JFC, and RMI. * How to use enterprise frameworks such as Enterprise JavaBeans and CORBA (via Java IDL) to access, retrieve, and store information across a network. Visit the Companion Web site at www.wiley.com/compbooks/govoni/ for: * Source code from the application objects presented in this book. * Links to more information on frameworks. |

| ssis performance tuning interview questions: Next Generation Databases Guy Harrison, 2015 It's not easy to find such a generous book on big data and databases. Fortunately, this book is the one. Feng Yu. Computing Reviews. June 28, 2016. This is a book for enterprise architects, database administrators, and developers who need to understand the latest developments in database technologies. It is the book to help you choose the correct database technology at a time when concepts such as Big Data, NoSQL and NewSQL are making what used to be an easy choice into a complex decision with significant implications. The relational database (RDBMS) model completely dominated database technology for over 20 years. Today this one size fits all stability has been disrupted by a relatively recent explosion of new database technologies. These paradigm-busting technologies are powering the Big Data and NoSQL revolutions, as well as forcing fundamental changes in databases across the board. Deciding to use a relational database was once truly a no-brainer, and the various commercial relational databases competed on price, performance, reliability, and ease of use rather than on fundamental architectures. Today we are faced with choices between radically different database technologies. Choosing the right database today is a complex undertaking, with serious economic and technological consequences. Next Generation Databases demystifies today's new database technologies. The book describes what each technology was designed to solve. It shows how each technology can be used to solve real word application and business problems. Most importantly, this book highlights the architectural differences between technologies that are the critical factors to consider when choosing a database platform for new and upcoming projects. Introduces the new technologies that have revolutionized the database landscape Describes how each technology can be used to solve specific application or business challenges Reviews the most popular new wave databases and how they use these new database technologies. |
