This book is intended for developers working on applications that use a database server. The book speci cally addresses the PostgreSQL RDBMS: it actually is the world’s most advanced Open Source database, just like it says in the tagline on the official website. By the end of this book you’ll know why, and you’ll agree! I wanted to write this book af er having worked with many customers who were making use of only a fraction of what SQL and PostgreSQL are capable of delivering. In most cases, developers I met with didn’t know what’s possible to achieve in SQL. As soon as they realized — or more exactly, as soon as they were shown what’s possible to achieve —, replacing hundreds of lines of application code with a small and e cient SQL query, then in some cases they would nonetheless not know how to integrate a raw SQL query in their code base. The introduction of this book intends to convince application developers such as you, dear reader, that there’s more to SQL than you might think. It begins with a very simple data set and simple enough queries, that we compare to their equivalent Python code. Then we expand from there with a very important trick that’s not well known, and a pretty advanced variation of it. A simple Python application is introduced as a practical example illustrating the different answers provided. In particular, this part insists on when to use SQL to implement business logic.

The ability to produce visualizations has become critical, increasingly sought-after. Data visualization simplifies the process of analyzing data by presenting it in a format that's easier for human brains to understand. Since our eyes are more drawn to colors and patterns than words and numbers, this tool helps communicate information much faster and efficiently using graphical representations such as charts, tables, and maps. For example, an organization can represent its sales data with a map on top of using words and numbers. This visual map, color-coded based on the sales numbers, would help people understand how these sales increase or decrease or how the trend moves over a certain period. Data visualization is a helpful tool for every field in which data plays an important role: industries ranging from marketing to finance to tech. As a result, the ability to produce visualizations has become an important, increasingly sought-after skill for coding in today’s data analysis. This skill has also led to the rise of visualization tools, such as PowerBI, Tableau, and Looker. This book introduces the basic concepts behind visualizations and provides examples of each in Tableau. Tableau offers step-by-step tutorials on how to create each visualization.

Давным-давно, в середине 90-х гг. прошлого века при появлении на свет самой первой версии Delphi (в те времена ещё принадлежащей компании Borland) о новой среде проектирования в первую очередь говорили как о превосходной платформе для разработки настольных и клиент-серверных приложений для баз данных. Спустя почти 20 лет Delphi не только не утратила своих позиций в этом сегменте компьютерного рынка, но и существенно нарастила свои возможности.

Evolving technological advances in Artificial Intelligence-empowered Software present significant potential to lead e-Government towards more collective efforts, exchange of experiences on best practices both at national and international levels and dissemination of secluded administrative knowledge. In this book, novel semantic web-based and linked open data-based approaches are developed for the modelling and management of the huge volume of administrative data and the procedures followed by public sector bodies and for the production and management of relevant administrative knowledge. Knowledge in Semantic Web is in the form of triplets RDF, to which specific languages are focused. Their main object is the recovery of results upon submission of tailored questions in the form of triplets. Such languages are RQL and SPARQL.

Mathematical Methods in Data Science introduces a new approach based on network analysis to integrate Big Data into the framework of ordinary and partial differential equations for data analysis and prediction. The mathematics is accompanied with examples and problems arising in Data Science to demonstrate advanced mathematics, in particular, data-driven differential equations used. Chapters also cover network analysis, ordinary and partial differential equations based on recent published and unpublished results. Finally, the book introduces a new approach based on network analysis to integrate Big Data into the framework of ordinary and partial differential equations for data analysis and prediction. There are a number of books on mathematical methods in Data Science. Currently, all these related books primarily focus on linear algebra, optimization and statistical methods. However, network analysis, ordinary and partial differential equation models play an increasingly important role in Data Science.
