Book Description
Analyze data like a pro, even if you’re a beginner. Practical SQL is an approachable and fast-paced guide to SQL (Structured Query Language), the standard programming language for defining, organizing, and exploring data in relational databases. Anthony DeBarros, a journalist and data analyst, focuses on using SQL to find the story within your data. The examples and code use the open-source database PostgreSQL and its companion pgAdmin interface, and the concepts you learn will apply to most database management systems, including MySQL, Oracle, SQLite, and others.* You’ll first cover the fundamentals of databases and the SQL language, then build skills by analyzing data from real-world datasets such as US Census demographics, New York City taxi rides, and earthquakes from US Geological Survey. Each chapter includes exercises and examples that teach even those who have never programmed before all the tools necessary to build powerful databases and access information quickly and efficiently. You’ll learn how to: • Create databases and related tables using your own data • Aggregate, sort, and filter data to find patterns • Use functions for basic math and advanced statistical operations • Identify errors in data and clean them up • Analyze spatial data with a geographic information system (PostGIS) • Create advanced queries and automate tasks This updated second edition has been thoroughly revised to reflect the latest in SQL features, including additional advanced query techniques for wrangling data. This edition also has two new chapters: an expanded set of instructions on for setting up your system plus a chapter on using PostgreSQL with the popular JSON data interchange format. Learning SQL doesn’t have to be dry and complicated. Practical SQL delivers clear examples with an easy-to-follow approach to teach you the tools you need to build and manage your own databases. * Microsoft SQL Server employs a variant of the language called T-SQL, which is not covered by Practical SQL.

Book Description
Why buy this book? Like many people, I also ask this question before spending my hard-earned bucks. In the existence of free web material and many well-written comprehensive books, this question gets more weight. SQL is older than most of us, so I can't claim to be conveying some extraordinary stuff through this book. What makes this title unique is its slender size. If you are looking for a real compact practical guide on SQL, then this book is for you. For beginners, I have tried to confine an ocean to a bucket in order to equip them with SQL knowledge in the shortest time possible. SQL language is too voluminous and exposure of every aspect of this huge language is a very tedious task. Keeping aside the least utilized features, this book is rolled out to focus on the more operational areas of the language. It is meant to help you learn SQL quickly by yourself. It follows a tutorial approach wherein hundreds of hands-on exercises are provided, augmented with illustrations, to teach you SQL in a short period of time. Without any exaggeration, the book will expose SQL in record time. The book explicitly covers a free platform of the world's number 1 DBMS to expose SQL: Oracle Database Express Edition. I have chosen Oracle XE because it is free to develop, deploy, and distribute; fast to download; and simple to administer. The second important reason, that might attract you as well, is that it comes bundled with Oracle Application Express (APEX), a rapid application development tool for creating internet facing applications that can be accessed via desktops, laptops, and mobile devices (such as smart phones and tablets). Once you have become proficient with the SQL language on this platform, you can easily explore other platforms on your own. In addition to Oracle, the following renowned database management systems are also covered: - MySQL - SQLite - Microsoft SQL Server - IBM DB2 - Microsoft Access - PostgreSQL - MariaDB This book is ideal for self-study, and it can also be used as a guide for instructor-led classroom training. This book is designed in such a way that you can learn SQL even if you do not have access to your PC. At the end of each chapter in this book, a section named "Test Your Skill" is provided, which evaluates the knowledge you gained in each chapter. This work is an attempt to cram the most useful information about SQL into a compact guide to put your exploration vehicle in the top gear.

Book Description
Bridge the gap between theory and reality by implementing real-world examples using the Sparx EA tool and ArchiMate® 3.1 specification to develop sophisticated enterprise architecture models serving every unit in your organization Key Features • Discover the various artifacts that enterprise architects need to develop for stakeholders to make sound decisions • Build a functional enterprise architecture repository that is rich in information, references, and metamodels • Learn how to use Sparx Enterprise Architect from scratch Book Description Most organizations face challenges in defining and achieving evolved enterprise architecture practices, which can be a very lengthy process even if implemented correctly. Developers, for example, can build better solutions only if they receive the necessary design information from architects, and decision-makers can make appropriate changes within the organization only if they know the implications of doing so. The book starts by addressing the problems faced by enterprise architecture practitioners and provides solutions based on an agile approach to enterprise architecture, using ArchiMate® 3.1 as an industry standard and Sparx EA as the modeling tool. You'll learn with the help of a fictional organization that has three business units, each expecting something different from you as the enterprise architect. You'll build the practice, satisfy the different requirements of each business unit, and share the knowledge with others so they can follow your steps. Toward the end, you'll learn how to put the diagrams and the content that you have developed into documents, presentations, and web pages that can be published and shared with any stakeholder. By the end of this book, you'll be able to build a functional enterprise architecture practice that supports every part of your organization. You'll also have developed the necessary skills to populate your enterprise architecture repository with references and artifacts. What you will learn • Discover how enterprise architects can contribute to projects and departments within organizations • Use Sparx Enterprise Architect to build a rich architecture repository • Learn about the ArchiMate® 3.1 specification as you apply it in real-world projects • Use the focused metamodel technique to build the information necessary for maintaining your repository's consistency and accuracy • Understand the importance of keeping architectural artifacts simple yet eye-catching • Define an operational model that fits your initial needs and expands as required Who this book is for This book is for enterprise architects at all architectural layers and practices of any maturity level. Many of the artifacts suggested in this book are inspired by The Open Group Architecture Framework (TOGAF®); however, familiarity with TOGAF® is not required. Whether you work within the business, applications, data, or technology layers, this book covers examples that apply to your work. Although not mandatory, experience modeling in Sparx Systems Enterprise Architect using any modeling language will be helpful. No prior knowledge of ArchiMate® is required to get started with this book.
