The text discusses the creation of a single view of a business by aggregating data from various source systems. The authors outline a 10-step methodology for achieving this goal, which includes the development and deployment phases. They also introduce the concept of a "single view maturity model," which describes the evolution of a project as it moves from read-only to write-enabled views of the data. The required database capabilities to support the single view include a flexible data model, intelligent insights, predictable scalability with always-on availability, and an enterprise deployment model. Case studies are presented for MetLife and CERN, highlighting the use of MongoDB as a solution for their single view projects. The authors conclude by emphasizing the benefits of applying the proven methodologies, tools, and technologies to create a single view of a business.
