Explore the objects that you create and their relationships. Flows, imported datasets, and recipes are created to transform your sampled data. After you build your output objects, you can run a job to transform the entire dataset based on your recipe and deliver the results according to your output definitions.
Within , the basic unit for organizing your work is the flow. The following diagram illustrates the component objects of a flow and how they are related:
Objects in a Flow
A flow is a container for holding one or more datasets, associated recipes and other objects. This container is a means for packaging for the following types of actions:
Creating relationships between datasets, their recipes, and other datasets.
Execution of pre-configured jobs
Data that is imported to the platform is referenced as an imported dataset. An imported dataset is simply a reference to the original data; the data does not exist within the platform. An imported dataset can be a reference to a file, multiple files, database table, or other type of data.
NOTE: An imported dataset is a pointer to a source of data. It cannot be modified or stored within .
NOTE: External sources of data are not supported in . All sources must be uploaded files.
After you have created an imported dataset, it becomes usable after it has been added to a flow. You can do this as part of the import process or later.
A recipe is a user-defined sequence of steps that can be applied to transform a dataset.
In a flow, the following objects are associated with each recipe, which are described below:
Outputs contain one or more publishing destinations, which define the output format, location, and other publishing options that are applied to the results generated from a job run on the recipe.
When you select a recipe's output object in a flow, you can:
References allow you to create a reference to the output of the recipe's steps in another dataset. References are not depicted in the above diagram.
When you select a recipe's reference object, you can add it to another flow. This object is then added as a reference dataset in the target flow. A reference dataset is a read-only version of the output data generated from the execution of a recipe's steps.
The following diagram illustrates the flexibility of object relationships within a flow.
|Standard job execution||Recipe 1/Job 1|
Results of the job are used to create a new imported dataset (I-Dataset 2). See Job Details Page.
|Create dataset from generated results||Recipe 2/Job 2|
Recipe 2 is created off of I-Dataset 2 and then modified. A job has been specified for it, but the results of the job are unused.
|Chaining datasets||Recipe 3/Job 3|
Recipe 3 is chained off of Recipe 2. The results of running jobs off of Recipe 2 include all of the upstream changes as specified in I-Dataset 1/Recipe1 and I-Dataset 2/Recipe 2.
|Reference dataset||Recipe 4/Job 4||I-Dataset 4 is created as a reference off of Recipe 3. It can have its own recipe, job, destinations, and results.|
Flows are created in the Flows page. See Flows Page.
Recipes are edited in the Transformer page, which provides multiple methods for quickly selecting and building recipe steps.
Macros: As needed, you can create reusable sequences of steps that can be parameterized for use in other recipes. For more information, see Overview of Macros.
Run Jobs: When you are satisfied with the recipe that you have created in the Transformer page, you can execute a job. A job may be composed of one or more of the following job types:
