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.

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

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.
  - 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

Item subclass

The subclass of an item represents the characteristics of the data. Both category and item types have the Item Subclass property.

To define the subclass of an item type:

Access the Properties for the selected category or item type.
For the Item Subclass property, select a value that defines the data for the type:

Number

Any number excluding active syntax objects. The interpretation can be either character or binary. See Number Item Subclass properties .

Text

Any character excluding active syntax objects. The interpretation can be either character or binary. See Text Item Subclass properties .

Date & Time

A valid date and time format based on the data. The interpretation can be either character or binary. See Date & Time Item Subclass properties .

Syntax

Syntax objects are used as separators between portions of data. A restricted set of values used to define a dynamic delimiter, initiator, terminator, or release character. The interpretation is character. A syntax object cannot be longer than 120 bytes. Syntax objects, used as syntax, cannot be mapped. See Syntax Item Subclass properties .

For text and syntax objects, character size constraints can be in bytes or characters. Numbers are considered in digits and date-time formats are sized by the format, such as CCYYMMDD.
