Data Integration

Data integration refers to the process of consolidating data from multiple heterogeneous data sources into a single, unified dataset (entity integration) or data view (virtual integration). The data integration workflow encompasses subtasks such as schema matching, table annotation, entity resolution, value normalization, data cleaning, and data fusion. This technology is widely applied in areas like data warehouses, data lakes, and knowledge base integration, aiming to enhance the availability and consistency of data to support complex data analysis and decision-making.
