2. File transfer
3. Shared database
4. Shared bus

Question 14

Direct invocation: application

Answer 14

Synchronous one-to-one module coupling

Question 15

Direct invocation: requirements

Answer 15

Modules must be active simultaneously

Question 16

File transfer: application

Answer 16

Offline batch-wise asynchronous, 1-to-n module coupling

Question 17

File transfer: requirements

Answer 17

Existence of predefined file structure

Question 18

Shared database: application

Answer 18

Flexible asynchronous n-to-m module coupling

Question 19

Shared database: requirements

Answer 19

Existence of predefined database, availability of transaction management

Question 20

Shared bus: application

Answer 20

Direct synchronous, flexible m-to-n module coupling

Question 21

Shared bus: requirements

Answer 21

Existence of standardized bus, modules must be active simultaneously
