Introduction to Scanners
A scanner is a pluggable component of Enterprise Data Catalog that extracts specific metadata, such as source metadata or profile metadata, from external data sources and stores the metadata in the catalog. A scanner typically maps to a single resource type. However, there can be more than one scanner for a resource type.
A scanner performs a scan job on the metadata sources to fetch metadata into the catalog. When Informatica releases newer resource types for specific data sources, you can plug in those scanners to the current installation of Enterprise Data Catalog without having to upgrade the installation.
