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.
Group properties
Explicit format
Fixed syntax
Guidelines for defining a fixed group

- 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
    - Group properties
      - Group subclass
      - Sequence group formats
      - Explicit format

        Fixed syntax
        Guidelines for defining a fixed group
        Explicit delimited syntax
      - Implicit format
      - Specifying a delimiter
      - 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.
  - Components
  - Partitioning
  - Type inheritance
  - Schema analyzer
  - Distinguishable objects
  - Functions and expressions

Guidelines for defining a fixed group

Each component must be a group with a fixed syntax or a fixed item. The item is padded to a fixed size or its minimum and maximum content size are equal.
Each component must have a specified range maximum. The maximum cannot be s.
If a component range minimum is not equal to the maximum, content is not required for optional component occurrences. For example, if a component is the item ShippingAddress (0:1) and ShippingAddress has a minimum content size of two characters, data may either contain: 1) all pad characters, or 2) if content is in the data stream, there must be a minimum of two characters for a ShippingAddress. If a component is a group, no content is required for any of the items contained in an optional occurrence of that component.
