• To build an infrastructure that can quickly adapt to change

• Based on component-based architecture– Components can be new or existing code modules

• Multi-tier Component Architecture offers:– Faster application development

– Longer application life

– Easier application maintenance

• ORB is the foundation for this new architecture
