Nowadays, data analysis is a skill that is in high demand in order to develop indicators and metrics to monitor our information systems. In order to pursue this mission, several methods, techniques and tools have been developed to cover this need in various aspects.
Database Management Systems (DBMS), along with their querying language, Structured Query Language (SQL), are considered a very important path in data analysis. Based on analytic queries directly executed on the server side, a wide range of indicators can be developed without going through intermediate application layers.
This book, composed of four chapters, studies SQL as a tool for data management and analysis. Although the concepts of this language are standardized, this book presents them with the Microsoft SQL Server Database Management System (DBMS) and focuses primarily on the analytical aspect of this language.
Analytical processing, also known as OnLine Analytical Processing (OLAP), consists of interrogating the data in order to develop synthetic information that can be used as indicators for the decision-maker. Business Intelligence (BI) has emerged as a field which seeks to support managers in decision-making. It encompasses the techniques, methods and tools for conducting analytically-based IT solutions, which are referred to as OLAP (OnLine Analytical Processing). Within this field, SQL has a role as a leader and is continuously evolving to cover both transactional and analytical data management.
This book discusses the functions provided by Microsoft SQL Server 2014/2016 in terms of business intelligence. The analytic functions are considered as an enrichment of the SQL language. They combine a series of practical functions to answer complex analysis requests with all the simplicity, elegance and acquired performance of the SQL language.
Drawing on the wide experience of the author in teaching and research, as well as insights from contacts in the industry, this book focuses on the issues and difficulties faced by academics (students and teachers) and professionals engaged in data analysis with the SQL Server 2014/2016 database management system.
