## Review checklist

- [ ] Define control in practical terms: Control means knowing who administers the account, where data is stored, how access is granted, and how records can be exported or deleted.
- [ ] Choose the smallest suitable architecture: A warehouse may support large analytical workloads while a simpler database or reporting store better suits a narrow workflow.
- [ ] Include the operating costs: Hosting, storage, APIs, monitoring, connector maintenance, and technical support can continue after a build.
