Prologue
There is no shortage of hyperbolic metaphors for the role of data in our modern economy—a tsunami, the new oil, and so on. From an IT perspective, data flows might best be viewed as the circulatory system of the modern enterprise. We believe the beating heart is change data capture (CDC) software, which identifies, copies, and sends live data to its various users.
Although many enterprises are modernizing their businesses by adopting CDC, there remains a dearth of information about how this critical technology works, why modern data integration needs it, and how leading enterprises are using it. This book seeks to close that gap. We hope it serves as a practical guide for enterprise architects, data managers, and CIOs as they build modern data architectures.
Generally, this book focuses on structured data, which, loosely speaking, refers to data that is highly organized; for example, using the rows and columns of relational databases for easy querying, searching, and retrieval. This includes data from the Internet of Things (IoT) and social media sources that is collected into structured repositories.
