The Pragmatic Programmers SQL Antipatterns
Book SynopsisYour database is the foundation of your application. Many programmers assume it's also the bottleneck of productive software development, but with the right techniques, this doesn't have to be true. SQL Antipatterns illustrates some of the most common misconceptions and pitfalls software developers face using relational databases. This book helps you to use a database to produce the most efficient results, and turn sluggish, inflexible code and thankless late-night hours into high-quality, reliable solutions and a job well done. The SQL database programming language is the core of most software in the world, but if you're like most software developers, you're self-taught in SQL, and you know just enough to get by. As a result, you might design fragile databases that cannot scale as the business grows, write queries that produce incorrect results and not know why, or deploy applications that are vulnerable to hackers. Don't reinvent the wheel to solve problems SQL was designed to solve--this book will teach you new SQL techniques for getting your job done. Whatever platform or programming language you use, whether you're a junior programmer or a Ph.D., SQL Antipatterns will show you how to design and build databases, how to write better database queries, and how to integrate SQL programming with your application like an expert. You'll also learn the best and most current technology for full-text search, how to design code that is resistant to SQL injection attacks, and other techniques for success.

His approach makes it both a useful primer for those new to Business Intelligence as well as a great reference for more seasoned pros." --Howard Dresner, Chief Research Officer Dresner Advisory Services "Anyone looking to rollout a business intelligence initiative or shore up a fledgling one can benefit from the BI Guidebook. Rick Sherman leaves no stone unturned and takes a deep dive into a complex and diverse field. Even a seasoned BI professional will enjoy having this book as a reference within arm's reach." --William McNight "One cannot manage a business or run any organization without measurement: knowing where you'v been, where you are and where you are going. But while BI is the key enabler for such quantitative enterprise management, it remains one of the more complicated areas of information technology. BI encompasses a wide range of expertise from the technical mastery of building data models to the psychological finesse of resolving conflicts between IT and business people.

Cambridge University Press Can We Be Wrong The Problem of Textual Evidence
Book SynopsisThis Element tackles the problem of generalization with respect to text-based evidence in the field of literary studies. When working with texts, how can we move, reliably and credibly, from individual observations to more general beliefs about the world? The onset of computational methods has highlighted major shortcomings of traditional approaches to texts when it comes to working with small samples of evidence. This Element combines a machine learning-based approach to detect the prevalence and nature of generalization across tens of thousands of sentences from different disciplines alongside a robust discussion of potential solutions to the problem of the generalizability of textual evidence. It exemplifies the way mixed methods can be used in complementary fashion to develop nuanced, evidence-based arguments about complex disciplinary issues in a data-driven research environment.Table of ContentsIntroduction, or What's Wrong with Literary Studies?; Part I.

Technics Publications LLC Logic and Relational Theory: Thoughts and Essays
Book SynopsisThis book is a revised, upgraded, and hugely improved version of an earlier one called Logic and Databases. Although its effectively a brand new book, therefore, the following remarks from that earlier book are still relevant here. First, logic and databases are inextricably intertwined. The relational model itself is essentially just elementary logic, tailored to database needs. Now, if youre a database professional, this wont be news to you -- but you still might not realize just how much everything we do in the database world is (or should be!) affected by logic. Logic is fundamental, and everywhere. As a database professional, therefore, you owe it to yourself to understand the basics of formal logic, and you ought to be able to explain (and perhaps defend) the connections between formal logic and database technology. And thats what this book is about. What it does is show, through a series of partly independent, partly interrelated essays, just how various crucial aspects of database technology -- some of them very familiar, others maybe less so -- are solidly grounded in formal logic. Overall, the goal is to help you realize the importance of logic in everything you do, and also, I hope, to help you see that logic can be fun.

Johny Morris’ style of writing is one I really adapt well too, a great mix of theory and experience with highlighted summary, risks and advice passages throughout.

Springer Nature Switzerland AG Data Warehousing and Analytics: Fueling the Data Engine
Book SynopsisThis textbook covers all central activities of data warehousing and analytics, including transformation, preparation, aggregation, integration, and analysis. It discusses the full spectrum of the journey of data from operational/transactional databases, to data warehouses and data analytics; as well as the role that data warehousing plays in the data processing lifecycle. It also explains in detail how data warehouses may be used by data engines, such as BI tools and analytics algorithms to produce reports, dashboards, patterns, and other useful information and knowledge.The book is divided into six parts, ranging from the basics of data warehouse design (Part I - Star Schema, Part II - Snowflake and Bridge Tables, Part III - Advanced Dimensions, and Part IV - Multi-Fact and Multi-Input), to more advanced data warehousing concepts (Part V - Data Warehousing and Evolution) and data analytics (Part VI - OLAP, BI, and Analytics).This textbook approaches data warehousing from the case study angle. Each chapter presents one or more case studies to thoroughly explain the concepts and has different levels of difficulty, hence learning is incremental. In addition, every chapter has also a section on further readings which give pointers and references to research papers related to the chapter. All these features make the book ideally suited for either introductory courses on data warehousing and data analytics, or even for self-studies by professionals. The book is accompanied by a web page that includes all the used datasets and codes as well as slides and solutions to exercises.Table of Contents1. Introduction.- Part I: Star Schema.- 2.
