A main goal of Statistics and Data Science for Teachers is to provide teacher educators with a resource to guide entire courses and professional development, or portions of courses and professional development when preparing teachers of all school level grade levels to teach the foundations of statistics and data science in their classrooms. In supporting the spirit of Pre-K–12 Guidelines for Assessment and Instruction in Statistics Education II (GAISE II): A Framework for Statistics and Data Science Education, this book presents statistical ideas through investigations and engagement with the statistical problem-solving process of formulating statistical investigative questions, collecting/considering data, analyzing data, and interpreting results. The book is organized into three sections: 1) “Statistics as a Problem-Solving Process”; 2) “Toward Data Science”; 3) “Probability Unpacked”. Within each of these sections, standard topics of descriptive statistics, associations and relationships, distributions, probability, and sampling distributions are all developed.

The past two decades have seen an explosion both in the volume of data we use, and our understanding of its management. However, while techniques and technology for manipulating data have advanced rapidly in this time, the concepts around the value of our data have not. This lack of progress has made it increasingly difficult for organisations to understand the value in their data, the value of their data and how exploit that value. Halo Data proposes a paradigm shift in methodology for organisations to properly appreciate and leverage the value of their data. Written by an author team with many years' experience in data strategy, management and technology, the book will first review the current state of our understanding of data. This opening will demonstrate the limitations of this status quo, including a discussion on metadata and its limitations, data monetisation and data-driven business models. Following this, the book will present a new concept and framework for understanding and quantifying value in an organisation's data and a practical methodology for using this in practice. Ideal for data leaders and executives who are looking to leverage the data at their fingertips.

Get onboard this journey into the land of streams. This is a complete hands-on book about Apache Flink, that follows real-life use cases and will help you learn how to create scalable end-to-end stream processing pipelines. This is a complete hands-on book about Apache Flink. The book follows real-life use cases and you will learn how to create end-to-end stream processing pipelines. We will be using Redpanda and Apache Kafka - along with other technologies - so an understanding of Apache Kafka and Redpanda concepts like topics/partitions and producers/consumers is nice to have. Apache Flink is the defacto solution when it comes to low-latency stream processing, but its unified API allows also for historic data processing with no code changes. Moreover, Flink is proven in production at an extremely large scale and it also has a rich ecosystem with a bright future ahead. The book is designed to teach you the theory and the practicals as fast as possible. The reader should be able to get from zero to production-ready applications fast with enough practice on the concepts introduced in the book, along with having enough knowledge to debug and troubleshoot when things go wrong.

Эта книга посвящена практическому взгляду на реляционную теорию и проектирование реляционных баз данных. Здесь не рассматриваются такие фундаментальные основы, как реляционная алгебра и реляционное счисление, но с множеством примеров и пояснений показаны основные понятия и подходы, необходимые для проектирования баз данных. Все схемы баз данных в этой книге приведены в нотации UML 2.1, созданы с использованием Sparx Enterprise Architect и (если речь идёт об уровнях проектирования, для которых это актуально) ориентированы на MySQL 8.0, Microsoft SQL Server 2019, Oracle 18c. Скорее всего, приведённые решения будут успешно работать на более новых версиях этих СУБД, но не на более старых.

Основное внимание в книге уделено практике использования SQL для решения типовых задач. В ней не рассматривается теория реляционных баз данных (предполагается, что вы с ней знакомы или сможете найти недостающую информацию), но представлено более 500 SQL-запросов: от базового выбора до использования представлений, триггеров, хранимых процедур и функций. Все примеры представлены в виде постановки и решения задач с использованием MySQL, MS SQL Server и Oracle, даны описания и анализ типичных ошибок. Все решения работают на MySQL Community Server 8.x, Microsoft SQL Server Express 2019 и Oracle 18c Express Edition и могут работать с более новыми версиями этих СУБД, но не будут работать со старыми версиями.
