Report readability, including conciseness, grammar, and style	2 points

For each architecture below, find information online that would indicate that a system or organization follows that architecture and not the others. Explain in detail (in 1 – 2 paragraphs) why you think the example you have chosen fits that architecture (and not another one). If you do not find explicit information, you will need to argue that a corresponding (real-life) company employs one of the following architectures using any implicit information on their website:

1. 1 Data mart bus with linked dimensional data marts
2. 2 Hub and spoke architecture
3. 3 Centralized data warehouse architecture
4. 4 Federated Architecture
