##  Data Object
  * Extract data objects mentioned on or near interface arrows. Link each data object to its respective interface and identify parent-child relationships between data objects.
  * Identify hierarchical data structures in the diagram. Extract parent data objects (e.g., 'Products') and their child elements (e.g., 'Product_Id', 'Product_Name').
  * Analyze small text labels near interfaces that represent data objects being transferred between systems. Connect these to the appropriate interfaces.
