Software architecture

Software architecture

1. The main function of the system determinates the architecture

2. Architecture in the discipline of computer hardware

   • Stored program

   • Secuential execution
     • Instructions are executed sequentially from one instruction to the next in order
   • CPU
     • It's primary function is to execute the instructions from the main memory

3. Defined by Perry and Wolf by the formula

   • Software architecture = {Elements, Form, Rationale}
     • The elements are the information that is used and transformed
     • The rationale captures the motivation of the choice of architectural style, the choice of elements and the form
     • The form consist of weighted properties and relationships
