Hybrid architecture in data management is a method that combines two different approaches to handle information efficiently: federated and centralized. In these architectures, data remains within its original, secure environment, managed by its original controllers, a characteristic of federated systems. Simultaneously, the architecture standardizes data across different sources for consistency and interoperability, akin to centralized systems.
According to the Preface of Hybrid Architectures for Intelligent Systems, “Hybrid architecture for intelligent systems is a new field of artificial intelligence concerned with the development of the next generation of intelligent systems.”
Hybrid architecture operates by synergistically combining the decentralized control of federated systems with the uniformity and efficiency of centralized data models. This approach is based on a secure environment under the management of local data controllers, a key aspect of federated systems. It allows healthcare providers and researchers to maintain control over their data.
The hybrid architecture applies standardized formats and protocols for data processing across different sources, akin to centralized systems. This standardization enables the consistent and interoperable use of healthcare data from diverse sources, facilitating seamless data integration and analysis.

Hybrid architecture in the context of data management, particularly in sectors like healthcare, combines the features of both federated and centralized systems. This blend aims to maximize the advantages of each while minimizing their drawbacks. Key aspects of hybrid architecture include:

Start by identifying various healthcare data sources such as hospitals, clinics, research institutions, and labs. Understand the nature of data each source holds, its format, and how it's currently managed. Assess the requirements for data privacy, security, and compliance with regulations like HIPAA.
Implement a federated system where each data source retains control over its data. This involves ensuring that data remains within its local environment and under the management of the original data custodians. This approach is for maintaining privacy and adhering to local data governance policies.
Develop or adopt standardized data formats and protocols for data sharing and integration. One common approach in healthcare is mapping data to a standardized model like OMOP CDM. This ensures consistency and facilitates data interoperability among disparate systems.
Create secure data sharing mechanisms that allow data to be shared or accessed without moving it from its original location. This can be achieved through APIs, secure data gateways, or other technologies that enable access to data under strict privacy and security protocols.
While keeping the data decentralized, implement a centralized querying system that allows researchers and healthcare professionals to access and analyze data from multiple sources in aggregate form. This system should be able to send queries to local databases, receive responses, and aggregate the results without compromising patient identity.
Implement robust security measures such as encryption, access controls, and audit trails to protect data during storage and transmission. Compliance with healthcare regulations for data protection is a must.
Leverage advanced analytics and AI tools that can operate on the aggregated data to extract meaningful insights. These tools can help in predictive modeling, patient care improvement, and research.
Educate all stakeholders, including IT staff, healthcare providers, and researchers, on how the hybrid architecture works, its benefits, and the necessity of maintaining data privacy and security.

It's necessary for healthcare providers to maintain control and privacy over their patient data, while still enabling the larger healthcare community to access vital aggregated data for research, analysis, and public health monitoring, especially in situations like the COVID-19 pandemic.
No, it actually enhances data security. By allowing data to stay in its original, secure environment and using secure methods for aggregate data sharing, hybrid architecture maintains high standards of data privacy and security.
Yes, one of the strengths of hybrid architecture is its scalability. It can accommodate the addition of new data sources and can adapt to changing data types and regulatory requirements, making it well-suited for large, dynamic healthcare systems.
Absolutely. While particularly beneficial in healthcare, hybrid architecture can be applied in any sector where there's a need to balance local data control with the benefits of centralized data analysis, such as finance, education, and government services.
