Logical data base design: A management-oriented approach Academic Article uri icon

abstract

  • A logical data base consists of data definitions and data relationships. It is typically very large and complex even for a small organization, but it is generally designed in an ad hoc manner. However, several approaches have recently been proposed that allow for a systematic logical data base design. To make a data base more useful to the managers, it is imperative to encourage and obtain their involvement in the initial phase of the logical data base design. "Surface semantic models" are used in the logical data base design process to increase this involvement. A special type of this, called a "hierarchical external view model", is proposed. It has been successfully used to develop a logical data base for the Department of Aging in Pennsylvania. © 1982.
