TAILIEUCHUNG - Lecture Software engineering: Lecture 4 - Ivan Marsic

Lecture 4: Software architecture. The main contents of this chapter include all of the following: Problem structure vs. solution structure, software architecture definition, architectural decisions & key concerns, architectural styles, documenting architecture: views. | Ivan Marsic Rutgers University LECTURE 4: Software Architecture Topics Problem Structure vs. Solution Structure Software Architecture Definition Architectural Decisions & Key Concerns Architectural Styles Documenting Architecture: Views Hierarchical Organization of Software Software is not one long list of program statements but it has structure Taxonomy of structural parts (abstraction hierarchy), but not representation of relationships between the parts and does not specify the function of each part System or product Subsystems/Modules Packages Classes/Objects Methods highest abstraction level lowest level Product line (or product family) Source code But first, why do we want to decompose systems? The hierarchy shows a taxonomy of the system parts, but not the procedure for decomposing the system into parts — how do we do it? Why We Want To Decompose Systems Tackle complexity by “divide-and-conquer” See if some parts already exist & can be reused Focus on .
