Schema design
A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.

- Files
  You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
- Connections
  A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.

  A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
  - Introduction to schema design
    Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - Type properties
    The properties of a type define the characteristics of the data objects of that type.
  - Item restrictions
    Item restrictions are an optional feature you can use to specify valid or invalid data objects for an item type. Item restrictions are grouped into three categories: Value, Character, and Range.
  - Components
  - Partitioning
  - Type inheritance
  - Schema analyzer
  - Distinguishable objects
  - Functions and expressions

Distinguishable syntax objects

The system must be able to distinguish between different syntax objects contained within a group. To ensure that the syntax objects are distinguishable, use the following guidelines:

If a component is unbound, make sure its delimiter and any delimiter contained in it is distinguishable from the delimiter of the group. If you get an analysis error, look for missing placeholders or components with a range maximum of s.
In a component or a contained component with the same delimiter as the type delimiter, the system assumes that the delimiter appears as a placeholder for every data object if data with the same delimiter follows it.
If the delimited group has a terminator, make sure that the delimiter and any contained delimiter is distinguishable from the terminator.
The schema analysis verifies if the above requirement is met in a non-partitioned group.
