   A: QuickSight provides an embedding SDK that enables you to embed interactive dashboards within your applications. This feature allows you to integrate QuickSight’s BI capabilities into your custom applications, providing users with seamless access to data insights.

9. Q: How does QuickSight ensure data security and compliance?
   A: AWS QuickSight adheres to AWS security best practices and compliances, such as encryption at rest and in transit, identity and access management, and regular security audits. Additionally, QuickSight is compliant with various industry standards like HIPAA, GDPR, and FedRAMP.

10. Q: How does AWS QuickSight handle data refresh and caching?
    A: QuickSight provides options to schedule data refreshes for datasets sourced from supported data sources. You can configure the refresh frequency depending on your data source and business requirements. QuickSight also caches query results and SPICE data to improve the performance of visualizations and reduce the load on data sources. This caching mechanism ensures faster data retrieval and minimizes latency. You can configure cache settings and data retention policies as needed.
