On the logical tool layer, these characteristics comprise number of databases (DB 1 versus DB n ), number of application components (AC 1 versus AC n ), number of software products and vendors (V 1 versus V n ), and communication patterns (star versus spaghetti architecture and CP 1 versus CP n , respectively). On the physical tool layer, we can, for example, distinguish the mainframe architecture (1-tier architecture or T 1 ) and the client-server architectural style (2-tier architecture or T 2 , 3-tier architecture or T 3 )."@en.
