Informatica Abbreviations and Definitions
Abbreviation Term Definition
  Application Services Application services represent server-based functionality. Application services include services that can have multiple instances in the domain and system services that can have a single instance in the domain. System services are created for you when you create the domain. Application services include the following services: The service process is the runtime representation of a service running on a node. The service type determines how many service processes can run at a time.
  connection A connection is a repository object that defines a connection in the domain configuration repository.

Create a connection to import data objects, preview data, profile data, and run mappings. The Developer tool uses the connection when you import a data object. The Data Integration Service uses the connection when you preview data, run mappings, or consume web services.

The Developer tool stores connections in the domain configuration repository. Any connection that you create in the Developer tool is available in the Administrator tool.
  Data Integration Service The Data Integration Service is an application service that performs data integration tasks for Informatica Developer. Data integration tasks include previewing data and running profiles and mappings.
  domain An Informatica domain is a collection of nodes and services. A node is the logical representation of a machine in a domain. Services for the domain include the Service Manager that manages all domain operations and a set of Application Services that represent server-based functionality.

The domain requires a relational database to store configuration information and user account privileges and permissions. The first time that you install the Informatica services, you must create the domain configuration repository in a relational database.

You use Informatica clients to access underlying Informatica functionality in the domain. The clients make requests to the Service Manager or to application services.
  Domain Configuration Repository The domain configuration repository is a set of domain metadata tables stored in a relational database. Each time an administrator makes a change to the domain, the Service Manager writes the change to the domain configuration repository.
  mapping A mapping is a set of inputs and outputs that represent the data flow between sources and targets.
  Model Repository The Model repository is a relational database that stores the metadata for projects. The Model repository also stores run-time and configuration information for applications that are deployed to a Data Integration Service.
  Model Repository Service The Model Repository Service is an application service that manages the Model repository. The Model repository is a relational database that stores the metadata for projects created in Informatica Developer. The Model repository also stores run-time and configuration information for applications that are deployed to a Data Integration Service.
  node A node is a logical representation of a physical machine in the domain. The node acts as a gateway to receive service requests from clients and route them to the appropriate service. Services and processes run on the node in a domain. The availability of a service or process on a node depends on how you configure the service and the node.

A single node installation consists of a domain with one node. The node hosts the domain. The Service Manager and all Informatica application services run on the node.

An installation on multiple nodes consists of a gateway node, which hosts the domain, and additional nodes that run Informatica application services. The Service Manager runs on all nodes in the domain.
  node type The node type determines whether the node can serve as a gateway or worker node and determines the domain functions that the node performs.
  node role The node role defines the purpose of the node. A node with the service role can run application services. A node with the compute role can perform computations requested by remote application services. A node with both roles can run application services and locally perform computations for those services. By default, each gateway and worker node has both the service and compute roles enabled.
  physical data object A physical data object is the representation of data that is based on a flat file, relational database, social media, or WSDL resource.
  profile Profiles determine the characteristics of columns in a data source, such as value frequency, percentages, and patterns.

You can create a profile for one or more columns in a data object and store the profile object in the Model repository.
  project A project is the top-level container that you use to store folders and objects in the Developer tool. Use projects to organize and manage the objects that you want to use for data integration solutions. You manage and view projects in the Object Explorer view. When you create a project, the Developer tool stores the project in the Model repository.
  Service Manager The Service Manager in the Informatica domain supports the domain and the application services. The Service Manager runs on each node in the domain.

It runs as a service on Windows and as a daemon on UNIX. When you start Informatica services, you start the Service Manager.

The Service Manager (and application services) control security.

The Service Manager manages users and groups that can log in to application clients and authenticates the users who log in to the application clients.

The Service Manager (and application services) authorize user requests from application clients.
  workflow A workflow is a graphical representation of a set of events, tasks, and decisions that define a business process. You use the Developer tool to add objects to a workflow and to connect the objects with sequence flows. The Data Integration Service uses the instructions configured in the workflow to run the objects.

A workflow object is an event, task, or gateway. An event starts or ends the workflow. A task is an activity that runs a single unit of work in the workflow, such as running a mapping, sending an email, or running a shell command. A gateway makes a decision to split and merge paths in the workflow.

A sequence flow connects workflow objects to specify the order that the Data Integration Service runs the objects. You can create a conditional sequence flow to determine whether the Data Integration Service runs the next object.
WSDL Web Service Definition Language The Web Service Definition Language, or WSDL, is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint.
