Chapter: Fundamentals of Database Systems - Introduction to Databases - Database System Concepts and Architecture In this section we specify an architecture for database systems, called the three-schema architecture,9 that was proposed to help achieve and visualize these characteristics. In relational databases, data is stored in tables (rows and columns) and data is extracted from them by selecting columns and rows that In existing business process management systems, process instances run independently from each other. A Distributed database is defined as a logically related collection of data that is shared which is physically distributed over a computer network on different sites.
