    Outputs
      Main Description
      • Fully identify entities, relationships, and attributes for each entity needed to support the requirements
      • Detail each entity's attributes and keys
      • Normalize the data
      • Take into account for both static and dynamic data behaviors
      Key Considerations
      • Data design and application logic design are highly dependent on and related to one another. Achieving good data design requires strong, ongoing teaming with application logic designers throughout the development cycle.
      • Physical implementation considerations are not factored in to logical database design. Independence from these concerns enables flexible yet stable data designs.
