The Logical View in Software Architecture

INTRODUCTION The 4+1 view model was designed to describe the system in different views, for different stakeholders, being separated in ‘logical’, ‘development’, ‘process’ and ‘physical’ views, which helps in graphically representing and describing the architectural solution designed (Kruchten, 1995). The idea of the 4+1 view model was to come up with a representational graphical manner [...]
