DEVELOPING COLDFUSION 9 APPLICATIONS
ColdFusion ORM

Perform create, read, update, delete operations on ORM Objects
In any data-centric application, you can perform the following operations on the database:
• Insert (Create)
• Update
• Retrieve
• Delete
Once the object relational model is defined in a ColdFusion application, you can perform CRUD operations on the
objects directly using the methods provided by ColdFusion ORM. ColdFusion ORM, in turn, takes care of persisting
the object in the database.
