Rules and Guidelines for Intelligent Structure Models

Rules and Guidelines for
Intelligent Structure Model
s

Consider the following rules and guidelines when you work with an
Intelligent structure model
:
  • The model that you select for a data object should match the structure of the expected input files for the data object as much as possible. If an input file does not match the model, or partially matches the model, there might be a large amount of unidentified data and data loss. Therefore, when you create the model, it is important to choose a file that represents the expected input files.
  • When you create an
    Intelligent structure model
    in
    Intelligent Structure Discovery
    , do not use duplicate names for different elements.
  • Ensure that the
    Intelligent structure model
    is valid before you add it to the Column Projection properties of the data object properties.
  • You can only use a Read transformation with an
    Intelligent structure model
    in a mapping. Do not create or use a Write transformation with an
    Intelligent structure model
    , as the mapping will fail.
  • When you create the
    Intelligent structure model
    , select the Data Integration Version that corresponds to your current Big Data Management version.
  • A data object with an
    Intelligent structure model
    parse PDF forms, Microsoft Word tables, and XML files whose size is less than the supported Hadoop split size of 256 MB.
  • An
    Intelligent structure model
    can parse the data within PDF form fields but not data outside the fields.
  • An
    Intelligent structure model
    can parse data within Microsoft Word tables. Other data is unidentified.
