Data warehousing is a technique for integrating data from multiple sources into a single, consistent data store, typically used for business intelligence and reporting.

Data federation is a technique that allows users to access data from multiple sources without physically moving the data, providing a unified view of the data.

Extract, Transform, Load (ETL) is a technique for integrating data from multiple sources by extracting the data, transforming it into a consistent format, and loading it into a target system.

Data migration is a technique for moving data from one system to another, typically used when replacing an old system with a new one.

Data federation creates a virtual layer that integrates data from multiple sources, allowing users to query the data as if it were stored in a single location.

Extract, Transform, Load (ETL) is often used for real-time data integration and processing, as it allows for the continuous extraction, transformation, and loading of data into a target system.

Data federation is often used for integrating data from structured and unstructured sources, as it allows for the integration of data from various sources without requiring a common data model.

Data warehousing involves creating a central repository of data that is used to support decision-making, typically used for business intelligence and reporting.

Data warehousing involves using a common data model to integrate data from multiple sources, allowing for the consistent storage and analysis of data.

Data federation involves using a mediator to translate queries and access data from multiple sources, allowing users to access data from various sources without requiring a common data model.

Data migration involves using a data bus to transfer data between different systems, typically used when replacing an old system with a new one.

Data lake is a technique for storing and processing large volumes of data in its raw format, typically used for big data analytics.

Data mesh is a technique for distributing data across multiple domains and services, allowing for decentralized data management and governance.

Hybrid data integration involves using a combination of multiple data integration techniques to achieve the desired level of data integration.

AI-Driven Data Integration involves using artificial intelligence and machine learning to automate and optimize data integration processes, improving the efficiency and accuracy of data integration.
