Описание: Get started on mastering the one language binding the entire database industry. That language is SQL, and how it works is must-have knowledge for anyone involved with relational databases, and surprisingly also for anyone involved with NoSQL databases. SQL is universally used in querying and reporting on large data sets in order to generate knowledge to drive business decisions.Good knowledge of SQL is crucial to anyone working with databases, because it is with SQL that you retrieve data, manipulate data, and generate business results. Every relational database supports SQL for its expressiveness in writing queries underlying reports and business intelligence dashboards. Knowing how to write good queries is the foundation for all work done in SQL, and it is a foundation that Clare Churcher's book, Beginning SQL Queries, 2nd Edition, lays well.

What You Will Learn
Write simple queries to extract data from a single tableCombine data from many tables into one business result using set operationsTranslate natural language questions into database queries providing meaningful information to the businessAvoid errors associated with duplicated and null valuesSummarize data with amazing ease using the newly-added feature of window functionsTackle tricky queries with confidence that you are generating correct resultsInvestigate and understand the effects of indexes on the efficiency of queries
Who This Book Is For
Beginning SQL Queries, 2nd Edition is aimed at intelligent laypeople who need to extract information from a database, and at developers and other IT professionals who are new to SQL. The book is especially useful for business intelligence analysts who must ask more complex questions of their database than their GUI–based reporting software supports. Such people might be business owners wanting to target specific customers, scientists and students needing to extract subsets of their research data, or end users wanting to make the best use of databases for their clubs and societies.

Описание:

The OECD's Programme for International Student Assessment (PISA) is gaining increasing attention among education authorities of the world. The number of participating economies almost doubled in the past one and a half decades, increasing from 43 in 2000 when it first started to 74 in 2015. PISA assesses the performance in Reading, Mathematics, and Science of 15-year-olds with different emphases rotating among the three subjects in different exercises.

The attention of the participating economies has been focused almost exclusively on the ranking results which are used to evaluate the standings and progress of their education systems, although PISA does cover many background conditions which might have influenced the performance. Interestingly, East Asian economies have been consistently in the leading positions, and Finland has been frequently cited as a model for the Western economies and even the world to emulate.

This monograph contains many secondary analyses of PISA data. It presents results of comparisons of Singapore, East Asian economies, and the world. It also points up some influencing factors such as time in and after school, test-language effect, administrative styles, and school environment. Statistical and measurement issues are also raised and demonstrated. Moreover, cultural differences are evoked as a plausible explanation of the differences observed between the East and the West.

This monograph, using mainly simple and layman language, equips educational administrators and policy makers with in-depth insights into some of the intricacies inherent in the PISA data for a more appropriate understanding. It is readily appreciated that such an understanding is needed to prevent misinterpretation and avoid unsound policy or wasteful action.

They stand between the sophistication of developed, states and the relative simplicity of most hunter-gatherer groups and early agriculturalists.
