Enterprise Data Catalog Concepts Overview
Enterprise Data Catalog helps you analyze and understand large volumes of metadata in the enterprise. You can extract physical and operational metadata for a large number of objects, organize the metadata based on business concepts, and view the data lineage and relationship information for each object.
The key concepts in Enterprise Data Catalog include catalog, resource, resource type, scanner, and schedule. Catalog stores all the metadata extracted from sources. Resource type represents different metadata source systems. Resource is a representation of a resource type, such as Oracle, SQL Server, or PowerCenter. Scanners fetch the metadata and save it in the catalog. Schedules determine the intervals at which scanners extract metadata from the source systems and save the metadata in the catalog.
