In Informatica Intelligent Cloud Services (IICS), expressions are used extensively for data transformations, calculations, and filtering within mappings, tasks, and other components. Expressions allow you to manipulate data, perform calculations, and apply conditional logic to transform input data into the desired output format. Here's an overview of how expressions are used in IICS:
Expression Transformation:
In mapping tasks, you can use the Expression transformation to define complex expressions for transforming input data. This transformation allows you to create calculated fields, perform string manipulations, apply mathematical functions, and implement conditional logic.
Filter Conditions:
Expressions can be used to define filter conditions in mapping tasks to selectively process data based on specific criteria. For example, you can use expressions to filter out rows that meet certain conditions or to route data to different targets based on predefined rules.
Join Conditions:
When joining data sources in a mapping, you can use expressions to define join conditions that specify how records from different sources should be matched based on common keys or criteria.
