When a user starts a authoring action (creating, editing, importing, etc.) on one or more records, he uses a Stepper.
A stepper defines the cluster of related records that is manipulated when authoring, as well as the wizard-like sequence of steps that drive the user through the authoring operation.
For example, a CreateContact stepper defines that:
Authoring Contacts consists in authoring Contacts and their attached Addresses. So the cluster of records contains several contacts and for each of them several addresses records.
Creating a contact goes through 3 steps: 1.General Info, 2.Addresses and 3.Comments. The second step (2.Addresses) is itself composed of two sub-steps: 1.Address Data and 2.Phone Numbers.
A stepper contains two types of steps:
Collection Steps show a set of records. The user may select one or more records and edit these records.
Form Steps show attributes of one record. A form step displays attributes using the layout and contents defined in a form. Multiple form steps are sequenced under a collection step, guiding users through the steps to create or modify a record.
|When using a stepper to author master data on behalf of a publisher (See Data Authoring Patterns for more information), only the first level of the stepper is used, and second level collections steps are ignored.|
As part of the data authoring flow, a steppers supports automated data transformations and data validations.
Automated transformations take place in the form of calls to Enrichers defined in the entities, or to Procedures declared in the model.
Data validations check that the data complies with data quality rules defined in the model, such as mandatory attributes, unique keys, SemQL validations, etc. When a data validation fails, it is raised to the user and may prevent that user from proceeding in the stepper.
