Answer English

what are Structural Models
start learning
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).

When are class diagrams used
start learning
Used when developing an object-oriented system model to show the classes in a system and the associations between these classes

Explain Association within class diagrams
start learning
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

Explain generalisation in class diagrams
start learning
a relationship in which one model element (the child) is based on another model element (the parent).

explain aggregation in class diagrams
start learning
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.

what are behavioural models?
start learning
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.

What is Data-Driven Modeling
start learning
Show the sequence of actions involved in processing data and generating an associated output: Sequence diagrams, Activity diagrams, Data-flow diagrams.

What is Event-Driven Modeling
start learning
Show how a system responds to external and internal events

what is Model-Driven Engineering
start learning
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
start learning
No concern for implementation details, Reduces likelihood of errors, Speeds up the design and implementation process, Allows for the creation of reusable application models.

what are the dissadvantages of Model-Driven Engineering
start learning
The abstractions are not always the right abstractions for the implementation
