Idea

I would like to get experience in system design. I will resolve the fictional problem.

Business task

We want a system where a client can manage all their company info. Some company changes must have a document for this change. For example: if a client wants to up company paid-up capital then our system can do this task with all paperwork. The client must get it with minimum documents, questions and headaches.

Goal

I have a solution architecture for this business task. The solution's architecture is the core mechanism for this issue expressed as models and services in the code. I have test cases for validation product requirements.

Assumptions

I don't pick a language. Just a plain TS
I don't choose and design an infrastructure and data centre works. I have ultimate and magical AWS. It can do everything.

First step: questions for stakeholders

All answers from my mind I - I S - stakeholders

I: Do we only work with existing companies? S: No, We should create a new company for our clients.

I: What is the difference between an existing company and not existing? S: The main difference is a not existing company can change their data as a client wants.

I: Do we have any limits for a not existing company? S: Yes, we have. if a not registered company has a corporate charter then our system must create documents for changing a paid-up capital, shares, etc.

I: How do we can change a registered company attribute? S: By a process with documents.

I: What countries do we work in? S: For example, in the SG. However, you should think about the whole world.

I: Do you know country based requirements? S: Currently, no anyways we are totally sure each country has them.

I: As I know, sometimes regions or states have special rules and laws. Should we consider them? S: Right now, no. In future, of course, yes.

I: Do we have operation specialists? S: Yes, we have.

I: What tasks are they doing now? S: They collect company data, like principal activities, shareholders, a website, etc.

I: Which attributes does a company have? S: name, description, principal activities, paid-up capital, shares, company members, registration number.

Summary:

country based system
- region based system
each company attribute can be a lock if a company registered
company attribute can be changed only by a special document process
