| Abstract: | Today's users want to access their data through fourth-generation languages, or 4GLs, and microcomputers. More flexible data bases are required to satisfy this growing need. These data bases must be based on the data as perceived by users, not as viewed by a system—the normalized approach to data base design provides for this. Data bases can be built that satisfy user needs and establish a logical design done only once regardless of the DBMS or computer system that will subsequently use the data. |
