What database should a FinTech company use to capture new customer profiles and link existing profiles while maintaining security requirements?

A FinTech company requires a database solution that not only supports the capture and linking of customer profiles but also adheres to strict security requirements. Amazon DynamoDB is particularly suited for this scenario due to its design as a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.

DynamoDB allows for flexible data modeling, which means that the company can easily create and modify the structure needed to accommodate various attributes of customer profiles without downtime. Its ability to handle high-velocity workloads is essential for capturing new information quickly, especially in a sector where customer data is continuously updated and linked to existing profiles.

Moreover, DynamoDB includes built-in security features such as encryption at rest and in transit, fine-grained access controls through AWS Identity and Access Management (IAM), and logging capabilities via AWS CloudTrail. These features ensure that sensitive financial data is protected and that the company can comply with regulatory requirements related to customer data security.

The other options, while valuable for certain use cases, do not align as closely with the need for flexibility, speed, and stringent security measures as DynamoDB. For instance, Amazon RDS and Amazon Aurora are relational databases that may not be as flexible as a NoSQL solution when it comes to rapidly evolving data
