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
    - Expressions and evaluations
    - Using functions
    - Syntax of a function
    - Function argument syntax
    - Functions that convert character-set encoding to the native code page
    - General functions
    - Bidirectional functions
    - Bit manipulation and testing functions
    - Conversion functions
    - Date/time functions
    - Error handling functions
    - External interface functions
      - DBLOOKUP
      - DBQUERY
      - DDEQUERY
      - EXIT
      - GET
      - JEXIT
      - PUT
      - RUN
      - RENAMEFILE
        The RENAMEFILE function renames the source file to that of the destination file. If the operation succeeds, the returned value is 0; if it fails, then an operating system-specific error number is returned.
      - HARDLINKFILE
        A hard link points or references to a specific space on the hard drive. Multiple files can be hard linked to the same space in the hard drive. If some data is changed on one of the hard linked files, all the other files reflect that change. The HARDLINKFILE function returns the hard link file's command status. On successful execution of this function: 0 is returned; on failure: an operating system-specific error code is returned.
      - SOFTLINKFILE
        A soft link points to a specific file, which in turn, references to a particular location on the hard drive. The soft link, also known as symbolic link is a second file that exists independently of its target. The SOFTLINKFILE function returns the soft (symbolic) link file's command status. On successful execution of this function: 0 is returned; on failure: an operating system-specific error code is returned.
      - COPYFILE
        The COPYFILE function copies the source file to the destination file. It returns the copy file command status. On successful execution of this function: 0 is returned; on failure: an operating system-specific error code is returned.
      - SLEEP
        The SLEEP function suspends the execution of the current map until the time-out interval elapses. The time-out or sleep interval is represented in milliseconds. On successful execution of this function: 0 is returned; on failure: -1 is returned.
