Federation Layer
Intermediate layer responsible for coordinating and aggregating queries to multiple distributed data sources. Translates virtual queries into native queries specific to each data source.
Semantic Layer
Business abstraction that maps technical data models to concepts understandable by users. Enables intuitive querying of complex data without knowledge of underlying structures.
Query Engine
Execution engine that optimizes and distributes virtual queries to appropriate data sources. Manages parallelization and result aggregation to ensure optimal performance.
Virtual Data Lake
Logical abstraction unifying access to multiple data lakes and warehouses without physical duplication. Provides a single query interface for distributed and heterogeneous data.
Virtual Connector
Software component establishing an abstract connection to a specific data source. Automatically translates protocols and data formats between the virtual layer and native systems.
Data Abstraction
Process of hiding the technical complexity of underlying data sources behind a unified interface. Allows users to interact with data without worrying about their physical location or format.
Query Optimization
Process of automatically improving query performance on distributed virtual data. Uses statistics, costs, and heuristics to determine the optimal execution plan.
Virtual Cache
Intelligent buffer memory temporarily storing results of frequently used queries. Accelerates data access while maintaining consistency with original sources.
Data Middleware
Intermediate software facilitating communication and data management between applications and heterogeneous sources. Provides abstraction, transformation, and orchestration in the distributed data ecosystem.
Data Broker
Intelligent intermediary managing negotiation, authentication, and routing of requests between data consumers and providers. Applies governance and security policies in real-time.
Virtual Integration
Approach to unifying source data without physical ETL, creating dynamically integrated logical views. Allows maximum flexibility with minimal impact on existing systems.
Unified View
Consolidated logical representation of data from multiple heterogeneous sources presented as a single entity. Facilitates cross-system analysis and reporting without data duplication.
Data Gateway
Secure entry point controlling access to virtualized data and enforcing security policies. Manages authentication, authorization, and monitoring of data flows.
Data Orchestration
Automated coordination of data flows and transformation processes in the virtualized environment. Ensures sequential and parallel execution of complex operations.
Virtualization Platform
Complete software infrastructure supporting data virtualization with connectors, query engine, and management. Provides tools for designing, deploying, and monitoring virtual data services.
Data Virtualization Server
Centralized server hosting virtualization layers and managing the execution of distributed queries. Coordinates connections to data sources and maintains virtualization metadata.
