This guide describes conceptual information about data design environment components when you want to use the data fabrication feature in HCL OneTest™ Server.
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.
Item properties
Number item subclass properties
NONE and Zero

Reference Guide
This guide describes conceptual information about data design environment components when you want to use the data fabrication feature in HCL OneTest™ Server.
- 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.
- 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.
  - 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 type properties
    - Basic type properties
    - Item properties
      - Item subclass
      - Number item subclass properties
        Interpret as binary
        Byte Length
        Byte order
        Interpret as character
        Size (digits)
        Separators
        Pad
        Regular expressions
        Restrictions
        National language
        NONE and Zero
        NONE > Special Value and Zero > Special Value
        Enter a value in the Special Value property if the item is NONE or Zero.
        NONE > Required on input and Zero > Required on input
        Select a value from the Required on input property list.

      - Date & Time item subclass properties
      - Syntax item subclass properties
    - Group properties
    - 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
  - Schema analyzer
  - Distinguishable objects

NONE and Zero

When the Item Subclass has a Number value and the Interpret as property has a Character value, the NONE and Zero properties are available. Expand the NONE or Zero property to specify an override data value to define the Special Value and Required on input properties.
