The ultimate objective of database analysis, design, and implementation is to establish an electronic repository that faithfully represents the conceptual and logical model of the manageable aspects of a user’s information domain. Enterprise and Web-enabled databases must satisfy a wide set of demands and constituents. Software engineering in general and database development in particular can be a complex, complicated process. There is probably no other product development process that faces the same amount of uncertainty, which may account for the high failure rate of software projects. This chapter expands on the growing body of literature in the area of data quality by proposing additions to a hierarchy of database quality dimensions that include model and behavioral factors in addition to the process and data factors.
