Informatica Domain

The Informatica domain is a server component that hosts application services, such as the Model Repository Service and the Data Integration Service. These services, together with domain clients, enable you to create and run mappings and other objects to extract, transform, and write data.

Application Services

Model Repository Service: The Model Repository Service is an application service that manages the Model repository. The Model repository stores metadata created by Informatica products in a relational database to enable collaboration among the products. Informatica Developer, the Data Integration Service, and the Administrator tool store metadata in the Model repository.
Data Integration Service: The Data Integration Service is an application service in the Informatica domain that performs data integration tasks for the Developer tool and for external clients.
Metadata Access Service: The Metadata Access Service is an application service that allows the Developer tool to access Hadoop connection information to import and preview metadata.

The Informatica domain can run other application services. For more information about Informatica services, see the Informatica Application Service Guide.

Domain Repositories

Informatica repositories, posted on SQL databases, store metadata about domain objects. Informatica repositories include the following:

Domain configuration repository: The domain configuration repository stores configuration metadata about the Informatica domain. It also stores user privileges and permissions.
Model repository: The Model repository stores metadata for projects and folders and their contents, including all repository objects such as mappings and workflows.
Monitoring Model repository: The monitoring Model repository stores statistics for Data Integration Service jobs. You configure the monitoring Model Repository Service in the domain properties.

In addition to these domain repositories, the Informatica deployment also requires a repository for Hive metadata. This repository is hosted on an SQL database. It stores Hive table metadata to enable Hadoop operations.

For more information about domain repositories, see the

Informatica Application Service Guide.
