There is such acronym overload in computing that I started this page so I could easily find them when I forget what they mean:
XMI (XML Metadata Interchange) - A Format used by many CASE tools to write out UML models for data exchange. Whilst this is a "Standard", there appear to be different versions from vendors.
POJO (Plain Old Java Objects) - Objects with just getters and setters, often used in domain modelling.
CRC (Class Responsibility Collaborator)
LDM (Logical Data Model)
MDA (Model Driven Architecture) - Focuses on business requirements rather than implementation detail
MOF (Meta-Object Facility)
ORM (Object Relational Mapping)
UML (Unified Modeling Language) - A visual language for representing models
PDM (Physical Data Model)
