One paragraph explaining the functionality which is represented by this graph. What the main flow is and what is its purpose.
API Gateway [Expand]
Acts as the single entry point for all client requests, routing them to the appropriate microservices, handling authentication, rate limiting, and load balancing.
Related Classes/Methods: None
Identity and Access Management (IAM) Service [Expand]
Manages user identities, authentication (e.g., OAuth2, JWT), and authorization policies across all services.
Related Classes/Methods: None
Questionnaire Management Service [Expand]
Provides functionalities for designing, versioning, publishing, and managing statistical questionnaires. It interacts with the Metadata Service to store questionnaire definitions.
Related Classes/Methods: None
A specialized component (likely a frontend application or a dedicated backend service) focused on creating and managing Data Definition Interface (DDI) specifications, which are then used by other services like the Integration Service.
Related Classes/Methods: None
Data Collection Service [Expand]
Manages the process of data collection, including survey administration, data entry, and initial validation based on published questionnaires. It stores collected raw data.
Related Classes/Methods: None
Metadata Service [Expand]
Central repository for all metadata, including DDI definitions, questionnaire structures, data schemas, and integration configurations. It provides metadata to other services.
Related Classes/Methods: None
Data Management Service [Expand]
Responsible for the long-term storage, retrieval, transformation, and quality assurance of collected statistical data. It provides APIs for data access and analysis.
Related Classes/Methods: None
Integration Service [Expand]
Manages external integrations, enabling seamless data import from and export to other systems and platforms. It handles data format conversions, communication protocols, and relies on DDI definitions for structured data exchange.
