This vertical 3-layer architecture diagram template is designed to help teams visualize the stacked hierarchy of a software system in a clear, top-to-bottom format. The primary target users are software architects, developers, and product teams needing to document system tiers and data dependencies. Users will begin by identifying user interface elements in the top Presentation Layer, then move down to specify business logic within the central Application Layer. Finally, they map out storage and information sources in the bottom Data Layer to complete the technical stack. This process allows teams to achieve a professional roadmap that clarifies system infrastructure.
