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.
Type properties
The properties of a type define the characteristics of the data objects of that type.

- 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.

      - Defining exclude characters
        During the run time, the data validation process uses the Exclude Character List group property to define a set of characters that are not allowed to exist in the data stream as data content.
      - Escaping an excluded character in the data content
        Select Release Exclude Characters when you configure the exclude character list to enable the release character to escape excluded characters. When enabled, a release character that precedes an excluded character in data content escapes the excluded character, and the data content passes validation.
    - XML properties in the schema
  - 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.

  - Partitioning
  - Type inheritance

Allow Excess Trailing Delimiters

The schema validation process allows data that contains excess trailing delimiters on sequence groups.

You can change the default setting for the Allow Excess Trailing Delimiters property to No so that the schema validation process, instead, fails data that contains excess trailing delimiters.

The schema validation process interprets a delimited sequence group that contains optional components at the end of its sequence, as having excess trailing delimiters.

For example, GROUPA contains the following components: COMPA (mandatory) , COMPB (optional) , COMPC (optional), and COMPD (optional). The group is infix-delimited by a tilde. The following data stream examples are valid for GROUPA:

A~B~C~D
A~B~C~
A~B~~
A~~~

For this example, you want the schema validation process to disallow all of the data stream examples that contain unnecessary or excess trailing delimiters. To disallow the excess trailing delimiters, you can change the setting for the Allow Excess Trailing Delimiters property to No. The result is that the validation process fails all of the examples except the first one.
