How Informatica Works and Architecture?

Informatica is a leading data integration and management platform used to extract, transform, and load (ETL) data from various sources into a unified and consistent format. It provides a range of tools and services to support data integration, data quality, data governance, and more. Let’s explore how Informatica works and its architecture:

Informatica Architecture:
Informatica’s architecture is based on a client-server model and consists of the following main components:

1. Informatica PowerCenter Services:

• Integration Service: The Integration Service is the core component responsible for executing the ETL processes. It reads data from source systems, applies transformations, and loads the data into target systems. It also manages workflow execution and session management.
• Repository Service: The Repository Service manages the metadata, which includes information about mappings, transformations, workflows, and sessions. It stores this metadata in a relational database called the Informatica repository.
• Web Services Hub: The Web Services Hub enables web service interactions between Informatica and external applications.

2. Informatica PowerCenter Clients:

• Designer: The Designer is a graphical tool used to create and manage metadata objects like mappings, transformations, and mapplets.
• Workflow Manager: The Workflow Manager is used to create, schedule, and monitor workflows. It allows you to define the flow of tasks and sessions to be executed.
• Workflow Monitor: The Workflow Monitor provides real-time monitoring and management of workflows and sessions. It gives visibility into job execution and performance statistics.
• Repository Manager: The Repository Manager is used to administer the Informatica repository. It allows you to perform tasks like creating folders, managing users, and controlling access to metadata.
• PowerCenter Administrator Console: This web-based tool is used to manage and monitor the Informatica domain, including services, resources, and security.

3. Informatica Repository:
The Informatica repository is a relational database that stores metadata about mappings, transformations, workflows, sessions, and other Informatica objects. It acts as a central metadata repository that allows different Informatica clients and services to share and access the metadata.

How Informatica Works:
The data integration process in Informatica involves the following steps:

1. Design Phase:

• Developers use the Informatica Designer to create metadata objects such as source definitions (representing source data structures), target definitions (representing target data structures), transformations (defining data manipulations), and mappings (defining the flow of data from sources to targets).
• Mapplets, reusable transformations, and other objects can also be created to enhance reusability and maintainability.

2. Metadata Registration:

• The metadata objects created in the Design phase are saved to the Informatica repository using the Repository Manager.

3. Workflow and Task Creation:

• In the Workflow Manager, developers define workflows that represent the order of task execution, such as loading data from sources, applying transformations, and writing to targets.
• Sessions are created within workflows to represent the individual ETL tasks.

4. Workflow Execution:

• The Workflow Monitor allows administrators to schedule and monitor the execution of workflows and sessions.
• The Integration Service reads workflow information from the repository, fetches metadata, and executes the tasks as defined in the workflow.

5. Data Extraction, Transformation, and Loading:

• The Integration Service reads data from the specified source systems, applies transformations (if any), and loads the transformed data into the target systems.

6. Error Handling and Monitoring:

• The Workflow Monitor provides real-time monitoring of workflow and session execution. It also helps in identifying and resolving errors or performance bottlenecks.

Informatica’s scalable and flexible architecture allows it to handle various data integration scenarios, from simple data transfers to complex ETL processes involving large volumes of data and multiple sources and targets. Its ability to handle data quality, data governance, and data profiling tasks makes it a comprehensive data integration platform for enterprises of all sizes.
