How well do you know Microsoft Office? Many students can follow specific step-by-step directions to re-create a document, spreadsheet, presentation, or database, but do they truly understand the skills it takes to create these on their own? Just as simply following a recipe does not make you a professional chef, re-creating a project step by step does not make you an Office expert. The purpose of this book is to teach you the skills to master Microsoft Office 365 in a straightforward and easy-to-follow manner. But Microsoft® Office 365: A Skills Approach goes beyond the how and equips you with a deeper understanding of the what and the why. Too many times books have little value beyond the classroom. The Skills Approach series has been designed to be not only a complete textbook but also a reference tool for you to use as you move beyond academics and into the workplace.

SPSS Statistics: A Practical Guide gives students step-by-step guidance through the process of using SPSS software to analyse, interpret and report on data. IBM SPSS Statistics is a flexible set of data analytic tools used throughout many disciplines. With SPSS Statistics: A Practical Guide we aim to introduce readers to a range of commonly used statistical procedures that can be performed with SPSS Statistics, and are typically included in the curricula of undergraduate applied statistics and research methodology units. Our approach is unashamedly practical, and highly visual. We take a hands-on approach to our subject matter, and work through each procedure in an illustrated, step-by-step fashion. Beyond the necessary focus on “doing”, we emphasise interpretation and reporting throughout this text, which contains hundreds of tables of tightly annotated SPSS Statistics output, and dozens of examples of how specific research findings can be communicated clearly and concisely.

The goal of this book is to introduce readers to three powerful command line utilities that can be combined to create simple yet powerful shell scripts for performing a multitude of tasks. The code samples and scripts use the bash shell, and typically involve very small text files so that you can focus on understanding the features of grep, sed, and awk. In the simplest terms, grep (global regular expression print) will search input files in data for certain words or word patterns and print the lines that match it. sed is useful for changing or modifying data. Awk is a programming language also used for searching a data file for certain patterns, but can also perform certain tasks on the pattern matches it finds. Aimed at a reader relatively new to working in a bash environment, the book is comprehensive enough to be a good reference and teach a few new tricks to those who already have some experience with these command line utilities.

This book is for those who will not settle for a black-box approach when working with a database. If you are eager to learn, prefer not to take expert advice for granted, and would like to figure out everything yourself, follow along. I assume that the reader has already tried using PostgreSQL and has at least some general understanding of how it works. Entry-level users may find the text a bit difficult. For example, I will not tell anything about how to install the server, enter psql commands, or set configuration parameters. I hope that the book will also be useful for those who are familiar with another database system, but switch over to PostgreSQL and would like to understand how they differ. A book like this would have saved me a lot of time several years ago. And that’s exactly why I finally wrote it. In the introductory chapter, I briefly touch upon the main database concepts that will serve as the foundation for all the further narration. I do not expect you to get much new information from this chapter but still include it to complete the big picture. Besides, this overview can be found useful by those who are migrating from other database systems.

The book will review how new and old privacy-preserving techniques can provide practical protection for data in transit, use, and rest. We will position techniques like Data Integrity, and Ledger. This book will use practical lessons in Data Integrity, and Trust, and data's business utility. This book is based on a good understanding and experience of new and old technologies, emerging trends, and a broad experience from many projects in this domain. This book will provide unique context about the WHY (requirements and drivers), WHAT (what to do), and HOW (how to implement), and review current state and major forces representing challenges or driving change, what you should be trying to achieve, how do you do it, including discussions of different options. We will also discuss WHERE (in systems) and WHEN (roadmap). Unlike other general or academic texts, this book is being written to offer practical general advice, outline actionable strategies, and include templates for immediate use. The book contains diagrams needed to describe the topics and Use Cases.
