It should be noted here that in the dependency diagram, the primary vital components are bold, underlined, and shaded in a different color. The arrows for the below entities indicate all desirable dependencies, i.e., dependencies based on PK. The arrows below the dependency diagram indicate less desirable dependencies: partial and transitive dependencies. As the below diagram suggests, Dependency Diagrams have no way to indicate multi-valued attributes, nor do they provide the means through which such attributes can be handled. Once again, a basic knowledge of modeling concepts indicates that normalization and design are part of the same process. As shown below, Education, Dependents, and Training are multi-valued attributes whose values are stored as strings.
