A Data Lake is a centralized repository of structured, semi- structured, and unstructured data, upon which you can run insightful analytics. This is my ultra-short version of the definition. While in the past we referred to a data lake strictly as the facility where all of our data was stored, nowadays the definition has extended to include all of the possible data stores that can be linked to the centralized data storage, in a kind of hybrid data lake that comprises flat-file storage, data warehouses, and operational data stores.

This book examines the recent trend of extending data dependencies to adapt to rich data types in order to address variety and veracity issues in Big Data. Readers will be guided through the full range of rich data types where data dependencies have been successfully applied, including categorical data with equality relationships, heterogeneous data with similarity relationships, numerical data with order relationships, sequential data with timestamps, and graph data with complicated structures. The text will also discuss interesting constraints on ordering or similarity relationships contained in novel classes of data dependencies in addition to those in equality relationships, e.g., considered in functional dependencies (FDs). In addition to exploring the concepts of these data dependency notations, the book investigates the extension relationships between data dependencies, such as conditional functional dependencies (CFDs) that extend conventional functional dependencies (FDs). Graph data have been widely observed in real-world applications, e.g., knowledge bases and social networks can be modeled as graphs. In such scenarios, entities are represented by the vertexes in the graphs, each of which has one class tag such as persons, attribute values and connections with other entities. With the consideration over three main components, class, relation and attribute, metalanguage for graph models is introduced to define how graph data is serialized and compiled in files or databases, e.g., eXtensible Markup Language (XML) and Resource Description Frameworks (RDFs).

This book sets out to address some of the issues that a smart city needs to overcome to make use of both the data currently available to them and how this can be enhanced by using emerging technology enabling a citizen to share their personal data, adding value. It provides answers for those within a smart city, advising their mayors or leaders on introducing new technology. We will cover the topic so as to enable many different public officials to be able to understand the situation from their own perspective, be they lawyers, financial people, service providers, those looking at governance structures, policy makers, etc. When “Big Data” first appeared on the scene, there was a strong interest developed regarding how it may be of benefit to a smart city. However, an issue was that there was a lack of good examples of Big Data in use, shown in an easily recognisable way for those running a city.

This book closes the gap between what people think Excel can do and what they can achieve in the tool. Over the past few years, recognition of the importance of effectively visualizing data has led to an explosion of data analysis and visualization software tools. But for many people, Microsoft Excel continues to be the workhorse for their data visualization needs, not to mention the only tool that many data workers have access to. Although Excel is not a specialist data visualization platform, it does have strong capabilities. The default chart types do not need to be the limit of the tool’s data visualization capabilities, and users can extend its features by understanding some key elements and strategies. Data Visualization in Excel provides a step-by-step guide to creating more advanced and often more effective data visualizations in Excel and is the perfect guide for anyone who wants to create better, more effective, and more engaging data visualizations. I stick with Excel because for my purposes (and for many other data practitioners like me), Excel is all I need. Hopefully my approach to Excel in this book will demonstrate that you can create great, effective visualizations without having to lean on an entire suite of data visualization tools.
