The Question for Our ShopWhich modules make up the shop, and where does the payment provider begin?
Here you get the overview: structure, interaction and decisions in the software architecture.
7 Building blocks
Starting hereSoftware architectureWhat is the system, and where does it end?
The shop consists of seven modules in one application; the payment provider is outside the system boundary.
Why is it designed this way?
The prescribed provider and the status clarification for payment P-731 shape the adapter; asynchronous invoice R-882 adds further situations.
Who sees and owns which parts?
Fault analysis needs the runtime view of the payment; the platform team connects the payment provider.
Known names – and where they are
Software architecture organises the load-bearing parts of a system. The context sets the scope, drivers shape the choice of structure, views make it understandable, and clear roles keep decisions and implementation connected.
Here you clarify which modules make up the shop and where the payment provider begins. From this you derive the system boundary, well-founded decisions, suitable views and clear responsibilities. Each building block shows its theme at our shop.
This is what you learnYou can explain the seven modules of the shop, the external payment provider and their directed relationships as an architecture overview.
In the shopThe shop is a modular monolith: a single application, internally divided into seven modules – catalogue, shopping cart, order, payment, warehouse, shipping and invoice. The payment provider is a foreign system outside the shop.
Software architecture OpenThis is what you learnYou can distinguish the system boundary of the shop from external people and neighboring systems.
In the shopThe shop accepts orders from customers and exchanges information with payment providers, shipping service providers and warehouse team. The internal shipping module prepares deliveries; the external transport partner transports them. The warehouse team also maintains the floor from the outside, while the warehouse module in the shop manages the reservations. All internal shop modules are within a single system boundary.
System context & system boundary OpenThis is what you learnYou can prioritize requirements, quality goals and constraints as concrete architecture drivers.
In the shopThe shop must accept orders, clarify payments reliably and work with a prescribed payment provider. The team prioritizes these influences over detailed decisions.
Architecture drivers OpenThis is what you learnYou can identify an architectural decision based on its effect on structure, interfaces and later changes.
In the shopThe shop team has made five decisions that go far beyond a single module: from system style to communication and data storage to patterns that multiple modules rely on.
Architecture decision OpenThis is what you learnYou can choose the right view for an architectural question and limit its scope of information.
In the shopAt the shop, the department, development, error analysis and operation need different images. All four show the same architecture, but each answers a different question and leaves out different ones.
Architecture views OpenThis is what you learnYou can distinguish technically necessary complexity from additionally introduced technical complexity.
In the shopDiscount rules and reservation periods are part of the shop business. Every technical decision adds situations that the business did not demand. Turn it on and see how the order B-1042 It becomes more complex.
Complexity OpenThis is what you learnYou can clearly assign the preparation, decision, implementation and examination of an architectural decision.
In the shopIn the payment integration of the shop, four roles work together. Each leads exactly one station and works on others – as in a squadron.
Architecture ownership OpenThese areas are technically directly related to Fundamentals & orientation together.
