Denormalizing data in Informatica Cloud involves transforming normalized data into a denormalized structure, typically for performance or reporting purposes. Here's a step-by-step approach: 1. _Create a new mapping_: In Informatica Cloud, create a new mapping to design the denormalization process. 2. _Add source and target definitions_: Define the source (normalized data) and target (denormalized data) structures. 3. _Use an Aggregator Transformation_: Add an Aggregator Transformation to group data and perform aggregation functions (e.g., SUM, AVG). 4. _Employ a Router Transformation (optional)_: If you need to split data into multiple targets based on conditions, use a Router Transformation. 5. _Utilize an Expression Transformation_: Apply an Expression Transformation to flatten or concatenate data, if necessary. 6. _Configure target load settings_: Set up the target load settings to accommodate the denormalized data structure. Some specific denormalization techniques in Informatica Cloud include: - _Flattening_: Use an Expression Transformation to concatenate or flatten data. - _Pivoting_: Employ an Aggregator Transformation with a pivot option to rotate data. - _Grouping sets_: Use an Aggregator Transformation with grouping sets to perform multiple aggregations. Remember to validate and test your mapping to ensure accurate denormalization. If you need more detailed guidance or have specific requirements, feel free to ask! read less
