Integration of multiple data sources

Definition

Integration of multiple data sources refers to the process of combining and synthesizing information from various databases and datasets to create a cohesive and comprehensive view. This approach is crucial in understanding complex biological interactions, as it allows researchers to gain insights that are not possible from a single source, enabling a more complete understanding of molecular functions and relationships.
