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.
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.
- 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.

CHOOSE

The CHOOSE function returns the object within a series whose position in the series corresponds to a specified number.

Syntax:: CHOOSE (series-object-name , single-integer-expression)
Meaning:: CHOOSE (from_these_objects , pick_the_nth_one)
Returns:: A single object whose index within the from_these_objects series matches the number specified by pick_the_nth_one. If that member of the series does not exist, CHOOSE returns "none".

You can use CHOOSE to use a variable value to specify the index for a particular object from a series. The CHOOSE function does not operate on a series object that was returned by another function, such as EXTRACT.

Examples

CHOOSE ( Row:DBSelect , 2 )
Returns the second Row
CHOOSE ( Set:Claim , INDEX ( Row:Header ) )
Returns the Set within the Claim that corresponds to the index of the Row of Header.
