The driving force behind any web application is the users of the appli- cation and the developers creating the application. During development, however, the interests and needs of the user can often fall behind, in favor of what the developer thinks they need. This development style of- ten leads to complicated user interfaces, poor design choices, and content overload. To mitigate against this, the daily interaction a user can have with an application and their overall opinion should be considered paramount during development. This book aims to provide the tools and knowledge required for the collection and analysis of data, irrespective of the format or source. This book places a dividing line between the types of data that can be collected from users. Active data is defined as data that is collected by providing the user with the means to enter their opinion, and sen- timent, toward a feature or topic. These solutions can often be seen on websites in the form of rating systems, feedback boxes, and user surveys. In contrast to this, passive data is defined as the data that is collected in the background without any direct user interactions. This data takes the form of browser fingerprinting, IP addresses, geolocation data, time spent on pages, and the location of the mouse during interactions with an application. With the advent of cloud storage solutions, more data is being re- tained than before. Sales data, transaction logs, and user surveys all become sources for data analysis. Data can come from a number of dif- ferent sources, some of which may have existed before an application has been developed. Emphasis is placed on collecting this data and placing it in a usable format for analysis. After this data has been collected, the analysis process can begin. sualizations can be generated. This book provides the foundations for creating meaningful insights and visualizations from the data that are relevant to both business and developer needs.
