Architecture is really more like 3 bridges:



There are 3 different types of architecture:

1. enterprise architecture (global) -- consists of:
   • business architecture
     • processes
     • workflows
   • data architecture
     • entities or "things"
     • relationships
     • metadata
   • application architecture
     • partitioning
     • integration
   • technology architecture
     • infrastructure -- foundation
     • applications -- layered on top of infrastructure
       • built -- developed
       • bought -- purchased
     • business intelligence -- layered on top of applications


2. Domain-specific Architecture
   • cross-functional or cross-organizational
   • domain specific -- e.g.,
     • security architecture
     • network architecture
     • "customer" architecture


3. Software Architecture
   • project-centric
   • application specific -- e.g.,
     • accounts payable
     • order entry
     • sales management
