We have a project from Software Engineering course where we act as a developer group that make an application for the customer group according to their needs. We wrote a SRS$($Software Requirements Specification$)$ document. Now, we are writing a SDD $($software design document$).$For context, we are doing an online grocery store. I am doing the Component Design part of the design document which is related to the System Architecture part of the SDD$.$ I will attach the part from SDD that corresponds to Component Design part. Here is the template: $3.$ System Architecture
