Informatica

 Informatica can handle a large amount of data. This tool will give a complete data integration solution for the data management system. This tool can be used for extracting required data from all systems and transforming the same data on its server and loading it in the data warehouse.

Informatica is used as an integration tool. This tool is based on the ETL architecture. It provides data integration software and also services for different industries, businesses, and government organizations as well as telecommunication, health care, insurance, and also financial services. It also integrates the data into another system.

Typical use cases of the Informatica tool

• An organization travels from an existing legacy system like a mainframe to a new database system. So that it will be existing data into a system that will be performed.
• Enterprises will set up their data warehouse which would require an ETL tool that moves data from the production system to the warehouse.
• Integration of data from many heterogeneous systems like multiple databases and file-based systems will be done using Informatica.
• Informatica will be used as a data cleansing tool.

Informatica ETL tool is better than its competitors as they offer a large range of product editions. Most of the popular platforms use Informatica technology. It also offers cloud-based services so that with minimal setup an industry will be using this tool. Informatica offers real-time data integration like business-to-business integration, Big data edition, Master data management, and connectors for social media and salesforce.

Why do we need this Informatica tool?

Informatica is seen as the picture wherever we have a data system available and at the backend, we want to perform certain operations on the data. It will be like cleaning up data, modifying the data which is based on a certain set of rules, or maybe simply loading bulk data from one system to another. Informatica software is going to offer a rich set of features like operations at a row level on data, integration of data from multiple structured, semi-structured, or maybe unstructured systems, and scheduling of data operations. It also has the feature of metadata, so the information about processing the data operations is served.

Informatica Power center Architecture

This Informatica PowerCenter has a service-oriented architecture. The Informatica ETL tool Architecture has 

1. Repository service- Responsible for maintaining Informatica metadata and also providing access to the same to other services.
2. Integration Service- Responsible for the movement of data from the source targets
3. Reporting Service- Enables the generation of reports.
4. Nodes- Computing platforms where the above services will be executed.
5. Informatica Designer- which is used for the creation of mappings between source and target.
6. Workflow manager- which is used to create the workflows and also other tasks and also their execution.
7. Workflow monitor- This is used to monitor the execution of workflows.
8. Repository manager- which is used to manage objects in a repository.

Informatica Domain

The Informatica domain is a basic administrative unit in Informatica tools. It is a collection of nodes and services. These nodes and services will be divided into folders and subfolders which are based on the administration requirement.

Node is a logical representation of a machine inside the domain. The node will be required to run services and processes for Informatica. The gateway node is responsible for receiving requests from different client tools and routing those requests to different nodes and services.

We have two types of services in the domain.

1. Application services- Here the application service represents the server-specific services like integration service, repository service, and reporting service. These services will run on different nodes based on the configuration.
2. Service Manager- The Service Manager manages domain operations like authentication, authorization, and logging. It also runs the application services on the nodes as well as manages users and groups.
