Application Services and Repositories

Application Services and Repositories

Enterprise Data Preparation
requires application services and repositories to complete operations.
Use the
Administrator tool
to create and manage the application services and configure connections to repositories. Application services can use the Secure Sockets Layer (SSL) protocol to connect securely to other services and to repository databases.
Enterprise Data Preparation
requires the following application services:
Enterprise Data Preparation Service
The
Enterprise Data Preparation Service
is an application service that runs the
Enterprise Data Preparation
application in the Informatica domain. When an analyst publishes prepared data, the
Enterprise Data Preparation Service
converts each recipe into a mapping.
When an analyst uploads data, the
Enterprise Data Preparation Service
connects to the HDFS system in the Hadoop cluster to temporarily stage the data. When an analyst previews data, the
Enterprise Data Preparation Service
connects to the Hadoop cluster to read from the Hive table.
Interactive Data Preparation Service
The
Interactive Data Preparation Service
is an application service that manages data preparation within
Enterprise Data Preparation
. When an analyst prepares data in a project, the
Interactive Data Preparation Service
connects to the Data Preparation repository to store worksheet metadata. The service connects to the Hadoop cluster to read sample data or all data from the Hive table, depending on the size of the data. The service connects to the HDFS system in the Hadoop cluster to store the sample data being prepared in the worksheet.
When you create the
Enterprise Data Preparation Service
, you must associate it with a
Interactive Data Preparation Service
.
Data Preparation repository
When an analyst prepares data in a project, the
Interactive Data Preparation Service
stores worksheet metadata in the Data Preparation repository.
Catalog Service
The Catalog Service is an application service that runs
Enterprise Data Catalog
in the Informatica domain. The Catalog Service manages the catalog of information assets in the Hadoop cluster.
When an analyst searches for assets in
Enterprise Data Preparation
, the
Enterprise Data Preparation Service
connects to the Catalog Service to return search results from the metadata stored in the catalog.
When you create the
Enterprise Data Preparation Service
, you must associate it with a Catalog Service.
Model Repository Service
The Model Repository Service is an application service that manages the Model repository. When an analyst creates projects, the
Enterprise Data Preparation Service
connects to the Model Repository Service to store the project metadata in the Model repository. When an analyst publishes prepared data, the
Enterprise Data Preparation Service
connects to the Model Repository Service to store the converted mappings in the Model repository.
You must associate the
Enterprise Data Preparation Service
with a Model Repository Service. Informatica recommends that you create a dedicated Model Repository Service and Model repository for use by
Enterprise Data Preparation
.
If you configure
Enterprise Data Preparation
to use rules, you must associate the Model Repository Service that manages the Model repository in which rule objects and metadata are stored with the
Interactive Data Preparation Service
.
Model repository
When an analyst creates a project, the
Enterprise Data Preparation Service
connects to the Model Repository Service to store the project metadata in the Model repository. When an analyst publishes prepared data, the
Enterprise Data Preparation Service
converts each recipe to a mapping. The
Enterprise Data Preparation Service
connects to the Model Repository Service to store the converted mappings in the Model repository.
Data Integration Service
The Data Integration Service is an application service that performs data integration tasks for
Enterprise Data Preparation
. When an analyst uploads data or publishes prepared data, the
Enterprise Data Preparation Service
connects to the Data Integration Service to write the data to a Hive table in the Hadoop cluster.
You must associate the
Enterprise Data Preparation Service
with a Data Integration Service. Informatica recommends that you create a dedicated Data Integration Service for use by
Enterprise Data Preparation
e.
If you configure
Enterprise Data Preparation
to use rules, you must associate a Data Integration Service with the
Interactive Data Preparation Service
. The Data Integration Service is required to run rules during data preparation.
