Hands-On SQL Server 2019 Analysis Services. Design and query tabular and multi-dimensional models using Microsoft's SQL Server Analysis Services

Steve Hughes, Adam Jorgensen

SQL Server Analysis Services (SSAS) continues to be a leading enterprise-scale toolset, enabling customers to deliver data and analytics across large datasets with great performance. This book will help you understand MS SQL Server 2019’s new features and improvements, especially when it comes to SSAS.First, you’ll cover a quick overview of SQL Server 2019, learn how to choose the right analytical model to use, and understand their key differences. You’ll then explore how to create a multi-dimensional model with SSAS and expand on that model with MDX. Next, you’ll create and deploy a tabular model using Microsoft Visual Studio and Management Studio. You'll learn when and how to use both tabular and multi-dimensional model types, how to deploy and configure your servers to support them, and design principles that are relevant to each model. The book comes packed with tips and tricks to build measures, optimize your design, and interact with models using Excel and Power BI. All this will help you visualize data to gain useful insights and make better decisions. Finally, you’ll discover practices and tools for securing and maintaining your models once they are deployed.By the end of this MS SQL Server book, you’ll be able to choose the right model and build and deploy it to support the analytical needs of your business.

Vue.js 3 Design Patterns and Best Practices. Develop scalable and robust applications with Vite, Pinia, and Vue Router

Pablo David Garaguso, Olaf Zander

If you’re familiar with the progressive Vue framework for creating responsive user interfaces, you’ll be impressed with its latest iteration, Vue 3, which introduces new concepts and approaches design patterns that are uncommon in other libraries or frameworks. By building on your foundational knowledge of Vue 3 and software engineering principles, this book will enable you to evaluate the trade-offs of different approaches to building robust applications.This book covers Vue 3 from the basics, including components and directives, and progressively moves on to more advanced topics such as routing, state management, web workers, and offline storage. Starting with a simple page, you’ll gradually build a fully functional multithreaded, offline, and installable progressive web application.By the time you finish reading this Vue book, not only will you have learned how to build applications, but you’ll also understand how to solve common problems efficiently by applying existing design patterns. With this knowledge, you’ll avoid reinventing the wheel for every project, saving time and creating software that’s adaptable to future changes.

Platform and Model Design for Responsible AI. Design and build resilient, private, fair, and transparent machine learning models

Amita Kapoor, Sharmistha Chatterjee

AI algorithms are ubiquitous and used for tasks, from recruiting to deciding who will get a loan. With such widespread use of AI in the decision-making process, it’s necessary to build an explainable, responsible, transparent, and trustworthy AI-enabled system. With Platform and Model Design for Responsible AI, you’ll be able to make existing black box models transparent.You’ll be able to identify and eliminate bias in your models, deal with uncertainty arising from both data and model limitations, and provide a responsible AI solution. You’ll start by designing ethical models for traditional and deep learning ML models, as well as deploying them in a sustainable production setup. After that, you’ll learn how to set up data pipelines, validate datasets, and set up component microservices in a secure and private way in any cloud-agnostic framework. You’ll then build a fair and private ML model with proper constraints, tune the hyperparameters, and evaluate the model metrics.By the end of this book, you’ll know the best practices to comply with data privacy and ethics laws, in addition to the techniques needed for data anonymization. You’ll be able to develop models with explainability, store them in feature stores, and handle uncertainty in model predictions.
