Setting Up a Flat File Schema 101
As a follow-up to a previous post about EXTOL Flat File Schema Delimiters we are revieing how fields can be easily defined in the EXTOL Schema editor.
Defining an EXTOL Schema for a delimited file or Fixed length file
In the example above, the EXTOL Flat File Schema will consist
of a 'File' Node and one or more 'Record' Nodes.
When we choose the 'Properties' tab, off of the 'File' Node,
we can CLICK the box for Fixed Length if the file is fixed
length. If the file is delimiter defined, we leave the box unchecked.
Defining a record in a flat file schema to occur multiple times
In the example above, the EXTOL Flat File Schema has a single
record can occur multiple times. We determined this characteristic
since the 'Constraints' tab has the box for Unbounded CLICKED.
Defining the fields in a EXTOL Flat File Schema
The EXTOL Flat File Schema has an editor that allows users to
modify field lengths for fixed length records. In the example
above, all the fields will be zero due to the record being delimiter defined.
