Preface
The sources and forms of data, along with the demand for acquiring, processing, and analyzing that data are increasing at a prodigious rate. From a curricular perspective, majors, programs, and courses are being designed to enable interested students to understand these topics and prepare themselves for the practice of these associated data skills. As the sources and forms of data increase, with a commensurate increase in the data providers and interfaces for accessing data, our interpretation of what constitutes a data system must keep pace. An understanding of these forms and sources of data is exactly what is needed in a broad introduction to data systems. Data systems encompasses the study of forms and sources of data, an increasingly important topic for both computer scientists and data scientists. This book covers data acquisition, wrangl
