An application architecture specifies the technologies to be used to implement one or more

information systems． It serves as an outline for detailed design， construction， and implementation． Given the models and details， include（）， we can distribute data and processes to create a general design of application architecture． The design will normally be constrained by architecture standards， project objectives， and （）． The first physical DFD to be drawn is the（）． The next step is to distribute data stores to different processors． Data（） are two types of distributed data which most RDBMSs support． There are many distribution options used in data distribution． In the case of （）we should record each table as a data store on the physical DFD and connect each to the appropriate server．
