Overview

The Catalog Service is an application service that runs Enterprise Data Catalog in the Informatica domain. The Catalog Service manages the connections between service components and the users that have access to Enterprise Data Catalog search interface and Catalog Administrator.
The catalog represents an indexed inventory of all the configured data assets in an enterprise. You can find metadata and statistical information, such as profile statistics, data asset ratings, data domains, and data relationships, in the catalog.
Note: Ensure that you import the Hadoop cluster certificates to the domain trust store before you create a Catalog Service for a Hadoop cluster that uses SSL protocol.

Associated Services

The Catalog Service connects to other application services within the domain.
When you create the Catalog Service, you can associate it with the following application services:
Model Repository Service
The Catalog Service connects to the Model Repository Service to access resource configuration and data domain information from the Model repository. When you create the Catalog Service, you provide the name of the Model Repository Service.
Data Integration Service
The Catalog Service connects to the Data Integration Service to perform jobs, such as generating profile statistics for the resources. When you create the Catalog Service, you provide the name of the Data Integration Service.
Informatica Cluster Service
If you installed Enterprise Data Catalog on the internal cluster, the Catalog Service connects to Informatica Cluster Service to administer and manage all the internal Hadoop cluster services, Apache Ambari server, and Apache Ambari agents. When you create the Catalog Service for an internal cluster deployment, you need to provide the name of the Informatica Cluster Service.
Content Management Service
The Catalog Service uses the Content Management Service to fetch reference data for data domains that use reference tables. When you create the Catalog Service, you can optionally provide the name of the Content Management Service.
