Workflows in Informatica PowerCenter are created by...
- Workflow creator
- Workflow monitor
- Workflow manager
- Workflow administrator
Correct Answer

A. Workflow manager

How does PowerCenter read data in a table?
- Column by column
- Row by row
- Column by row
- Row by Column
Correct Answer

A. Row by row

Explanation

PowerCenter reads data in a table row by row. This means that it will process each row of data individually before moving on to the next row. This method allows for efficient and accurate data retrieval and transformation, as it ensures that each row is processed in the correct order and any necessary calculations or transformations are applied to the data in a sequential manner. Reading the data row by row also allows PowerCenter to easily handle large datasets without overwhelming system resources.

- Data monitor
- Workflow
- Mapping
- Path
Correct Answer

A. Mapping

Explanation

Mapping can be described as the pictorial representation of data flow from source to target. It visually represents how data is transformed and transferred from one system or database to another. It shows the connections and transformations between different data elements, providing a clear picture of the flow of data from its origin to its destination.

6.

Which of these tasks is not performed by ETL?
- Extraction of data from sources
- Updating of warehouses
- Creation of data
- Summarizing data
Correct Answer

A. Creation of data

Explanation

ETL stands for Extract, Transform, and Load, which are the three main processes involved in data integration and management. The extraction of data from sources, updating of warehouses, and summarizing data are all tasks performed by ETL. However, the creation of data is not typically a task performed by ETL. ETL is primarily focused on extracting data from various sources, transforming it into a suitable format, and loading it into a target data warehouse or database. The creation of data usually falls under the responsibility of data entry or data generation processes, rather than ETL.

PowerCenter is the _________-driven data integration platform.
- Prodata
- Metadata
- Microdata
- Data
Correct Answer

A. Metadata

Explanation

PowerCenter is the metadata-driven data integration platform because it uses metadata to define and manage the data integration processes. Metadata is the information about the data, such as its structure, format, and relationships, which PowerCenter uses to transform and move data between different systems. This allows PowerCenter to have a centralized control and understanding of the data integration processes, making it more efficient and reliable.
