Data Integration Service Architecture Overview

Data Integration Service Architecture Overview

The Data Integration Service receives requests to run data transformation jobs from client tools. Data transformation jobs include mappings, previews, profiles, SQL queries to an SQL data service, web service operation mappings, and workflows. The Data Integration Service connects to other application services, databases, and third-party applications to access and transform the data.
To perform data transformation jobs, the Data Integration Service starts the following components:
Data Integration Service process
The Data Integration Service starts one or more Data Integration Service processes to manage requests to run jobs, application deployment, job optimizations, and data caches. Multiple service components run within a Data Integration Service process. Each service component performs a specific function to complete a data transformation job.
DTM instance
The Data Integration Service starts a DTM instance to run each job. A DTM instance is a specific, logical representation of the execution Data Transformation Manager (DTM). The DTM is the compute component of the Data Integration Service that runs jobs.
The Data Integration Service can run on a single node or on a grid. A grid is an alias assigned to a group of nodes that run jobs. When you run a job on a grid, you improve scalability and performance by distributing jobs to processes running on multiple nodes in the grid.
