Manages node configuration metadata. Registers license information and verifies license information when you run application services. Provides accumulated log events from each service in the domain. You can view logs in the Administrator tool and the Workflow Monitor. Manages users, groups, roles, and privileges.
Application Services When you install Informatica, the installation program installs the following application services: Manages the connections to Informatica Analyst. Performs data integration tasks for Informatica Analyst, Informatica Developer, and external clients.
Manages connections to the PowerCenter repository. Runs PowerCenter sessions and workflows. Exposes PowerCenter functionality to external clients through web services.
Runs the Data Analyzer application. Runs the JasperReports application. Runs the Metadata Manager application. The repository stores information required to extract, transform, and load data. It also stores administrative information such as permissions and privileges for users and groups that have access to the repository. You administer the repository through Informatica Administrator and command line programs.
You can develop global and local repositories to share metadata: The global repository is the hub of the repository domain. Use the global repository to store common objects that multiple developers can use through shortcuts. These objects may include operational or application source definitions, reusable transformations, mapplets, and mappings.
A local repository is any repository within the domain that is not the global repository. Use local repositories for development. From a local repository, you can create shortcuts to objects in shared folders in the global repository. These objects include source definitions, common dimensions and lookups, and enterprise standard transformations. You can also create copies of objects in non-shared folders. You can view repository metadata in the Repository Manager.
You can also create a Reporting and Dashboards Service in the Administrator tool and run the PowerCenter Repository Reports to view repository metadata. When you work with a mapping template, you use the following main areas:.
In the Workflow Manager, you define a set of instructions to execute tasks such as sessions, emails, and shell commands. This set of instructions is called a workflow. The Workflow Manager has the following tools to help you develop a workflow:.
Create tasks you want to accomplish in the workflow. Create a worklet in the Worklet Designer.
A worklet is an object that groups a set of tasks. A worklet is similar to a workflow, but without scheduling information. You can nest worklets inside a workflow. Create a workflow by connecting tasks with links in the Workflow Designer. You can also create tasks in the Workflow Designer as you develop the workflow.
When you create a workflow in the Workflow Designer, you add tasks to the workflow. The Workflow. Manager includes tasks, such as the Session task, the Command task, and the Email task so you can design a workflow. The Session task is based on a mapping you build in the Designer. You then connect tasks with links to specify the order of execution for the tasks you created. Use conditional links and workflow variables to create branches in the workflow. When the workflow start time arrives, the Integration Service retrieves the metadata from the repository to execute the tasks in the workflow.
You can monitor the workflow status in the Workflow Monitor. You can monitor workflows and tasks in the Workflow Monitor. You can view details about a workflow or task in Gantt Chart view or Task view. You can run, stop, abort, and resume workflows from the Workflow Monitor.
You can view sessions and workflow log events in the Workflow Monitor Log Viewer. The Workflow Monitor displays workflows that have run at least once.
It also fetches information from the repository to display historic information. Displays monitored repositories, servers, and repositories objects.
Displays messages from the Integration Service and Repository Service.
Displays details about workflow runs in chronological format. Displays details about workflow runs in a report format. The following figure shows the Workflow Monitor interface:. A repository client is any PowerCenter component that connects to the repository.
The Repository Service is a separate, multi-threaded process that retrieves, inserts, and updates metadata in the repository database tables. The Repository Service ensures the consistency of metadata in the repository. The Repository Service accepts connection requests from the following PowerCenter components:. Create and store mapping metadata and connection object information in the repository with the PowerCenter Designer and Workflow Manager.
Retrieve workflow run status information and session logs with the Workflow Monitor. You will learn why Informatica is such a popular ETL tool. Informatica from Intellipaat Informatica Certification course and fast-track your career.

Informatica is the most widely used data integration tool and there are very goods for this as listed below: Informatica is an extremely feature rich tool that lets you do a lot of operations including row level operations on data, integrating all types of data including structured, unstructured and semi-structured and it also lets you store metadata which is the data of all the data processes and operations.
Repository Service — It maintains the Informatica metadata and offers access to other services. Integration Service — it lets you move the data from various sources onto the target. Informatica Designer —This is used for creating the mapping between the source and the target. Workflow Manager — This is used for creating the workflow and other tasks along with their execution.
Informatica is being extensively used across the world in organizations that want to stay on top of their data. Along with that Informatica is your gateway into the world of big data. Thus there are organizations that are offering top-notch salaries for professionals who are well-versed in this top ETL tool.
This has led to an increase in the demand for certified Informatica professional. This data needs to be processed to give insightful information for making business decisions. They would be available in multiple databases and many unstructured files.
This data must be collated, combined, compared, and made to work as a seamless whole. Many organisations have implemented interfaces between these databases, but they faced the following challenges: Every pair of databases requires a unique interface.
If you change one database, many interfaces may have to be upgraded. Below you can see the various databases of an organisation and their interactions: Various Databases used by different departments of an organization Different Interactions of the Databases in an Organisation As seen above, an organisation may have various databases in its various departments and the interaction between them becomes hard to implement as various interaction interfaces have to be created for them.
To overcome these challenges, the best possible solution is by using the concepts of Data Integration which would allow data from different databases and formats to communicate with each other.
Various Databases connected via Data Integration But there are different processes available to perform Data Integration.
Among these processes, ETL is the most optimal, efficient and reliable process. Through ETL, the user can not only bring in the data from various sources, but they can perform the various operations on the data before storing this data on to the end target. Let us now understand the steps involved in the Informatica ETL process.
In ETL, Extraction is where data is extracted from homogeneous or heterogeneous data sources, Transformation where the data is transformed for storing in the proper format or structure for the purposes of querying and analysis and Loading where the data is loaded into the final target database, operational data store, data mart, or data warehouse. The below image will help you understand how the Informatica ETL process takes place.
Now, let us look at the steps involved in the Informatica ETL process. It is the process of obtaining a snapshot of the chosen subset of data from the source, which has to be loaded into the data warehouse. A snapshot is a read-only static view of the data in the database. Phase 1: Extract or Capture 2. As seen in the image below, this is the second step of Informatica ETL process.
Phase 2: Scrubbing or Cleaning of data 3. Transform: As seen in the image below, this is the third and most essential step of Informatica ETL process. Transformations is the operation of converting data from the format of the source system to the skeleton of Data Warehouse. A Transformation is basically used to represent a set of rules, which define the data flow and how the data is loaded into the targets. Phase 3: Transformation 4.
In this stage, we place the transformed data into the warehouse and create indexes for the data. Incremental load or Refresh load: The modified data alone will be updated in target followed by full load. The changes will be captured by comparing created or modified date against the last run date of the job.
