This topic covers general concepts that are important to understand about transformations.
These pages are included in this topic:
- Instance and Multiple Mapping
You can create transformation mappings when the source and target schemas use the same or different data structure types. Depending on which data structure types are used, the transformation mapping may be described as instance or multiple mapping.
- Nodes and Fields
Nodes and fields are contained within the schemas that are specified either during activity configuration or in the transformation. While configuring a transformation, nodes and fields are displayed the same regardless of the transformation display mode.
- Transformation Processing
Jitterbit Harmony supports streaming and chunking as methods of processing a transformation. A streaming transformation is the preferred method to use when the amount of memory a transformation uses needs to be limited. In cases where you are unable to use a streaming transformation, chunking may be applicable.
Also see the topic Schema Basics for information about schemas:
- When to Use a Schema
Whether a file schema is required depends on the type of activity and if it is being used as a source or a target of a transformation. Whether you choose to define a schema within a transformation or as part of an activity depends on your use case.
- Schema Processing
When defining a schema, some data may be converted during processing. This page describes how this data is converted.
- Schema Menu Actions
This page describes the actions available for schemas after they are created, accessible from the project pane or the transformation. These include deleting, viewing dependencies of, deploying, or configurable deploy of a schema, as well as editing the configuration of an activity providing a schema, editing a schema, or clearing a schema from a transformation.
