Diagrams in the Documentation & Implementation style help people understand the technical details of an implementation or a product at all levels of depth.
The images in the following templates show how a made-up Salesforce B2C Commerce application might look. The examples start with a system map, which is a picture of the whole answer. At each level after the first, the example images zoom in on a more specific part of the system or application.
As you move from a higher level to a lower level, the example images show more specific details and focus on smaller and smaller places. In the finished image, the finest elements are shown.
Level 1: An overview
At this stage, maps show a bigger picture of a solution or system layout. Diagrams at this level are best at showing the goods or technologies used in a specific solution or application, but they don’t show many details. The goal of these images is to show the “big picture” without giving too much information.
The sample system map below shows a picture of a B2C business solution, showing how Salesforce goods and other technologies are used.
Level 2: Part Of The Entire
Diagrams at Level 2 show parts of a solution picture or system layout, just like diagrams at the level above. But at this level, people wouldn’t be able to see the whole system or solution environment.
These diagrams show a subset of the goods or technologies that make up a solution in more depth than a higher-level diagram can. At this level, you might see things like the general direction of data flows or the key interaction places.
Using our B2C commerce solution as an example again, the level 2 image shows the design of the shop storefront solution. In this layer, we only see the goods and tech that are directly involved. We also get more information about how the integration works and what its key functions are.
We don’t see any exchanges or data flows that depend on time. Diagrams in the levels below are the best way to show that level of depth.
Level 3: View of a Process or Interaction
designs at this level have more fine details than designs at the two levels above. These images only show a small part of the goods or technologies that make up a solution.
This is done so that more complicated details can be shown clearly. Diagrams at Level 3 might show interactions that depend on time, data flow, or interactions between systems that are needed to help a process work.
In our case of B2C trade, the order on behalf of the procedure is shown in the Level 3 image. Only goods or technologies that have an immediate role in the process are shown, along with more information about the steps and how the flow works.
Level 4: Clicking twice
At this stage, diagrams show the most detailed information about a part of a method or system. This level is the best way to show technology standards or specs that are very exact. Level 4 images should be the most limiting in terms of what they show or how they show it so that even though they show more information, it is still easy to understand.
Keeping with our B2C business example, the Level 4 graphic shows how a chat-based order-on-behalf method flows. In the image below, you can see the parts of this part of the whole “order on behalf” process, down to the smallest grain.
