Display the organization of a system in terms of the components that make up that system and their relationships, Static (structure of the system design) vs Dynamic (organization of the system when it is executing).
Association is a relationship between classifiers which is used to show that instances of classifiers could be either linked to each other or combined logically or physically into some aggregation
is a specialised form of Association where all objects have their own lifecycle, but there is ownership and child objects can not belong to another parent object.
Model the dynamic behaviour of the system as it is executing, Data arrives that has to be processed by the system, Event happens that triggers systems processing.
Show the sequence of actions involved in processing data and generating an associated output: Sequence diagrams, Activity diagrams, Data-flow diagrams.
Approach to software development where models rather than programs are the principal outputs of the development process, The programs that execute are then generated automatically from the models.
what are the bennefits of Model-Driven Engineering
No concern for implementation details, Reduces likelihood of errors, Speeds up the design and implementation process, Allows for the creation of reusable application models.
