The ifx_getMartdef() function returns the value of the data mart definition. For example:

<?xml version="1.0" encoding="UTF-8" ?>
<dwa:martModel xmlns:dwa="http://www.ibm.com/xmlns/prod/dwa" version="1.0">
  <mart name="orders_customer_mart">
    <table name="customer" schema="informix" isFactTable="false" >  
      <column name="customer_num"/>
      <column name="fname"/>
      <column name="lname"/>
      <column name="state"/>
    </table>
    <table name="orders" schema="informix" isFactTable="true" >

    </table>
    <reference
      referenceType="LEFTOUTER"

      parentCardinality="1"
      dependentCardinality="n"
      dependentTableSchema="informix"
      dependentTableName="orders"
      parentTableSchema="informix"
      parentTableName="customer">
       <parentColumn name="customer_num"/>
       <dependentColumn name="customer_num"/>
