Centralized data system

« Back to Glossary Index

Definition: In this type of data system, all participating source systems copy their data to a single, centrally-located data repository where they are organized, integrated, and stored using a common data standard. Data in a centralized Statewide Longitudinal Data System (SLDS) are periodically matched, integrated, and loaded into a central repository. Users query the system and can access the data to which they have been authorized to view and use.
