Elements of Database Systems

Read chapter 2, which continues the top-down discussion on DBMSes. It describes the elements of a DBMS, functional requirements and necessary characteristics (which corresponds to the external view of the 3-level schema architecture perspective), design (which corresponds to the conceptual model view), and implementation (which corresponds to the internal/physical model view). It also gives an overview of database and DBMS processes, including planning, development techniques and methods, roles and responsibilities, stakeholders, and database and DBMS maintenance and configuration control (which is how to control changes to the database or DBMS).
