1 logical design
"A design process that details the elements of the solution and how they interrelate with each other. This design does not provide technical implementation details, and thus is prior to making specific technology decisions." -
2 physical design
"The third major stage in the design process, in which the project team determines how to specifically implement the logical design. Physical design addresses the technology that will be used by the end user. The goal is to apply real-world technology constraints to the logical design, such as implementation and performance considerations. Physical design corresponds to a contractor's blueprints for the physical elements of a structure-wiring, plumbing, heating, and ventilation. The contractor's plans add detail to the architect's plans and reflect real-world construction constraints." -
3 analysis
"In conceptual design, the breaking down and examination of business and user information into use cases and scenarios documenting work processes. In logical design, the identification of services, objects, attributes, and relationships from scenarios. In physical design, the examination of physical constraints of the infrastructure and the physical requirements of the application to select candidate implementation technologies and to draft a preliminary deployment model."
