     • Advanced data integration capabilities, including ETL, data quality, and data governance

3. How does Informatica Cloud differ from Informatica PowerCenter?

   • Informatica PowerCenter is an on-premises data integration solution, while Informatica Cloud is a cloud-based platform.
   • Informatica Cloud offers a more modern, cloud-native architecture and a user-friendly interface.
   • Informatica Cloud provides faster deployment, automatic updates, and seamless scalability compared to PowerCenter.

4. What are the key components of Informatica Cloud?

   • The key components of Informatica Cloud include:
     • Data Integration Hub: A centralized platform for designing, executing, and monitoring data integration tasks.
     • Application Integration Hub: Enables integration between cloud applications and on-premises systems.
     • Data Quality and Governance: Ensures data accuracy, consistency, and adherence to governance policies.
     • Intelligent Cloud Services: Provides advanced capabilities like machine learning and artificial intelligence for data integration.

Data Integration Tasks and Transformations

1. What is a Synchronization task in Informatica Cloud?

   • A Synchronization task in Informatica Cloud assists in integrating data between a source and a target. It allows users to apply transformations, filter data, and retrieve data from other objects.

2. Explain the Replication task in Informatica Cloud.

   • The Replication task enables users to replicate data from a database table or an on-premises application to a target. It supports incremental processing, allowing for efficient data replication.

3. What is the difference between a Synchronization task and a Replication task?

   • A Synchronization task is focused on integrating data between a source and a target, while a Replication task is specifically designed for replicating data from a source to a target.
   • Replication tasks offer built-in incremental processing capabilities, while Synchronization tasks require manual handling of incremental data processing.

4. What is a Mapping Configuration task in Informatica Cloud?

   • A Mapping Configuration task in Informatica Cloud is similar to a mapping in Informatica PowerCenter. It allows users to define parameters, pre-and post-processing commands, and advanced session parameters for optimized performance.

5. How do you handle incremental loading in Informatica Cloud?

   • Informatica Cloud provides system variables like $LastRunTime and $LastRunDate that can be used as data filter variables to filter recently inserted or updated records, enabling incremental loading.

6. What is Dynamic Linking in Informatica Cloud?

   • Dynamic Linking in Informatica Cloud allows users to generate new target files or tables at runtime during mapping execution. This feature enables flexibility in target file naming and creation.

7. How do you read JSON source files in Informatica Cloud?

   • In Informatica Cloud, JSON files can be read using the Hierarchy Parser transformation. Users need to define a Hierarchical Schema that describes the structure of the expected output data, and the Hierarchy Parser transformation will parse the JSON file based on this schema.

8. Explain Partitioning in Informatica Cloud.

   • Partitioning in Informatica Cloud enables parallel processing of data by dividing it into multiple partitions. It supports two partitioning strategies:
     • Key Range Partitioning: Distributes data based on a partition key and value ranges.
     • Fixed Partitioning: Suitable for non-relational sources, allowing users to specify a fixed number of partitions.

Data Quality and Governance

1. How does Informatica Cloud ensure data quality?

   • Informatica Cloud offers a comprehensive Data Quality and Governance module that provides features like:
     • Data profiling and data quality rules
     • Data cleansing and standardization
     • Address verification and geocoding
     • Reference data management

2. What is the role of Data Governance in Informatica Cloud?

   • Data Governance in Informatica Cloud helps organizations implement policies and processes to ensure data accuracy, consistency, and compliance with regulatory and business requirements.
   • It includes features like data lineage, data cataloging, and data masking for sensitive data protection.

3. How can Informatica Cloud help with data migration and consolidation?

   • Informatica Cloud simplifies data migration and consolidation by providing:
     • Broad connectivity to various data sources and targets
     • Advanced data transformation and mapping capabilities
     • Automated data quality checks and cleansing
     • Support for batch and real-time data integration
