Peter Bailis, Joseph M. Hellerstein, and Michael Stonebraker wrote:In the ten years since the previous edition of Readings in Database Systems, the field of data management has exploded. Database and data-intensive systems today operate over unprecedented volumes of data, fueled in large part by the rise of “Big Data” and massive decreases in the cost of storage and computation. Cloud computing and microarchitectural trends have made distribution and parallelism nearly ubiquitous concerns. Data is collected from an increasing variety of heterogeneous formats and sources in increasing volume, and utilized for an ever increasing range of tasks. As a result, commodity database systems have evolved considerably along several dimensions, from the use of new storage media and processor designs, up through query processing architectures, programming interfaces, and emerging application requirements in both transaction processing and analytics. It is an exciting time, with considerable churn in the marketplace and many new ideas from research.

In this time of rapid change, our update to the traditional “Red Book” is intended to provide both a grounding in the core concepts of the field as well as a commentary on selected trends. Some new technologies bear striking resemblance to predecessors of decades past, and we think it’s useful for our readers to be familiar with the primary sources. At the same time, technology trends are necessitating a re-evaluation of almost all dimensions of database systems, and many classic designs are in need of revision. Our goal in this collection is to surface important long-term lessons and foundational designs, and highlight the new ideas we believe are most novel and relevant.
