The conceptual solution overview section provides an abstract-level diagram that captures a big-picture view of the whole solution, which includes both business and technical aspects. It provides a basis for analyses and trade-off studies that can help refine and optimize the solution architecture in sufficient detail, to support solution design and implementation. The following diagram illustrates a conceptual architecture diagram of an e-commerce platform:

The preceding diagram shows an abstract view of significant modules and information flow between them. The conceptual architecture provides a good understanding of the overall architecture for both business and technical users. However, technical users need further architectural depth. Let's dive deeper into the solution architecture, in the next section.
