Would require information from each of these silos. Indeed, whenever you move from one database paradigm to another, there is an inherent, and often unknown, cost. A simple example might be the process of moving from a relational database to a key–value database. Already managed data must be migrated, software must be installed, and new engineering skills must be developed. Making smart choices at the beginning of the design process may mitigate these problems. In Chapter 3, “Building a NoSQL-Based Web App to Collect Crowd-Sourced Data,” we will discuss the process of using a NoSQL database to build an application that expects a high level of volume from users.
Is the list of parties concatenated into a single string and stored in a field all by itself?

Among these was none other than Larry Ellison, who helped found a company with the inauspicious name Software Development Laboratories. This company later evolved into Oracle, and Ellison’s commercial success made him one of the richest people in the world.
