How Data Virtualization Works
Data virtualization works by creating a logical data layer between consumers and underlying sources, acting as an intermediary and masking the complexity of each dataset’s storage, formats, and locations. When users submit queries through data virtualization engines, relevant information from various sources is extracted, transformed, or joined as needed before being presented as one unified view.
An effective data virtualization solution typically comprises various components, including:
- Data Virtualization Server: This core engine handles query optimization, data access, and transformation operations.
- Data Sources: Repositories that house the data, such as databases, cloud platforms, or APIs.
- Metadata Repository: Stores metadata about underlying data sources, including their structure, relationships, and access permissions.
- Query Optimizer: Analyzes incoming queries to identify the most efficient means of retrieving and processing required information.
- Security and Access Control: Ensures that only authorized users can view specific data, supporting data governance policies.
Integration is a fundamental aspect of data virtualization. This process involves connecting to various data sources and comprehensively understanding their contents. This allows the data virtualization engine to convert user queries into the appropriate formats for each source, ensuring accurate and meaningful results.
