Learn the most important SQL skills and apply them in your job - quickly and efficiently! SQL (Structured Query Language) is the modern language that almost every relational database system supports for adding data, retrieving data, and modifying data in a database. Although basic visual tools are available to help end-users input common commands, data scientists, business intelligence analysts, Cloud engineers, Machine Learning programmers, and other professionals routinely need to query a database using SQL. Job Ready SQL provides readers with an understanding of relational databases and Structured Query Language (SQL). SQL is a domain‐specific language designed for managing data held in a relational database management system. This book contains a full‐fledged SQL course that is used by the Wiley Edge Global Academy and the Software Guild to train our alumni in SQL and other topics, such as data analysis and Data Science.

Written for students in undergraduate and graduate statistics courses, as well as for the practitioner who wants to make better decisions from data and models, this updated and expanded third edition of Fundamentals of Predictive Analytics with JMP bridges the gap between courses on basic statistics, which focus on univariate and bivariate analysis, and courses on data mining and predictive analytics. Going beyond the theoretical foundation, this book gives you the technical knowledge and problem-solving skills that you need to perform real-world multivariate data analysis. The software used in many initial statistics courses is Microsoft Excel, which is easily accessible and provides some basic statistical capabilities. However, as you advance through the course, because of Excel’s statistical limitations, you might also use some nonprofessional, textbook-specific statistical software or perhaps some professional statistical software. Excel is not a professional statistics software application; it is a spreadsheet. Using JMP 17, this book discusses the following new and enhanced features in an example-driven format.

Gain deep insight into real-time analytics, including the features of these systems and the problems they solve. With this practical book, data engineers at organizations that use event-processing systems such as Kafka, Google Pub/Sub, and AWS Kinesis will learn how to analyze data streams in real time. The faster you derive insights, the quicker you can spot changes in your business and act accordingly. The term “streaming” describes a continuous, never-ending flow of data with no beginning or end. The data is made available incrementally over time, which means that you can act upon it without needing to download everything in one go. A data stream consists of a series of data points ordered in time. Each data point represents an “event” or a change in state that has occurred in the business. For example, a customer purchasing a product becomes an event, which captures facts about the person, product, price, and transaction time.

The modern data stack has evolved rapidly in the past decade. Yet, as enterprises migrate vast amounts of data from on-premises platforms to the cloud, data teams continue to face limitations executing data transformation at scale. Data transformation is an integral part of the analytics workflow–but it's also the most time-consuming, expensive, and error-prone part of the process. Today, integrating data into business operations is table stakes. Winning organizations will have the most performant and scalable architectures, prioritize the value of their outputs, and place the greatest emphasis on results. We’ve seen this pattern in other operational groups: engineering, sales, and marketing, to name a few. From workplace wikis to a slew of Slack apps, automation and tooling drive process improvement, which multiplies the value-add of passionate, curious employees—this is the premise of the modern data stack (MDS).

Most existing companies struggle currently because they lack the tools and strategies to move product departments into independent platforms that can be retrofitted to form dynamic new products based on consumer demands. This book provides managers and professionals with the necessary approaches for designing software and hardware architectures to support data platform organizations. Specifically, it demonstrates how to automate the decomposition of existing platforms into smaller parts that can be reused to form new variations. This task requires significant analysis and design methodologies and procedures to create an infrastructure based on data as opposed to products. These new knowledge bases allow data-centric professionals to pursue actions that can better predict and respond to the unexpected. Data orchestration is a process where software that accesses siloed data from multiple sources and systems combines it into a common formatted repository for general access. DataOps, short for data operations, is the practice that applies agile engineering techniques with DevOps best practices to the field of data management.

Do you know what happens to your personal data when you are browsing, buying, or using apps? Discover how your data is harvested and exploited, and what you can do to access, delete, and monetize it. Data for All empowers everyone—from tech experts to the general public—to control how third parties use personal data. The data you generate every day is the lifeblood of many large companies—and they make billions of dollars using it. In Data for All, bestselling author John K. Thompson outlines how this one-sided data economy is about to undergo a dramatic change. Thompson pulls back the curtain to reveal the true nature of data ownership, and how you can turn your data from a revenue stream for companies into a financial asset for your benefit. Descriptive statistics are the statistical methods that we learned in high school and college. These are statistical techniques like averages—means, modes, and Gaussian distributions. Data scientists use these tools to create an exploratory data analysis (EDA).

You want the very best application performance and you don't want to be limited by the capabilities of your infrastructure. That starts with application design. In this report, you'll discover how to build distributed transactional applications that deliver reliability, scalability, resilience, and elasticity. Kubernetes controls, or orchestrates, the containers that comprise a distributed application. A Kubernetes cluster consists of a number of nodes, each of which hosts one or more containers. Kubernetes provides a high-level abstraction called a Pod. A Pod consists of one or more containers with shared storage, networking, and namespaces. Although it might be possible to implement a microservice entirely in a single container, modularity is improved by allowing for containers that implement shared services across multiple Pods. Pods also often include sidecar containers. The sidecar typically provides common services across a range of Pods, such as monitoring, alerting, logging, and network abstraction. This report is for software developers, architects, and operational staff who want to understand the benefits and challenges of distributed transactional software architecture.
