Answer #1

1. Classification of artifact design methods are as follows :

Artifact-driven Architecture Design :It approaches as those approaches that extract the architecture description from the artifact descriptions of the method
Use-Case driven Architecture Design : In this approach,use cases are used as the primary artifacts for deriving the architectural abstractions.
Domain-driven Architecture Design : This approaches derive the architectural design abstractions from domain models. Domain models are developed through a domain analysis phase represented by the function
Product-line Architecture Design : In this approach, an architecture is developed for a software product-line that is defined as a group of software- intensive products sharing a common, managed set of features that satisfy the needs of a selected market area.
Domain Specific Software Architecture Design : The domain-specific software architecture may be considered as a multi-system scope architecture, that is, it derives an architectural description for a family of systems rather than a single-system.

2. Reference Architecture vs Application architecture

Reference architecture is a set of documents whereas application architecture is a map structure.
Reference architecture is used by team members of a project to refer for best practices whereas application architecture are used by software developers to see how a software is assembled.
Reference architecture is an abstraction whereas application architecture is an implementation.

3. Procedure of Artifact driven method :

Clients describes the requirement specifications
Then a search of artifacts is done in the analysis phase such as classes in requirement specification.
The search process is supported by the general knowledge of the software engineer and the heuristic rules of the artifacts that form an important part of the method.
The result of the search function is a set of artifact instances that is represented by the concept Analysis &Design Models.
Then defines the overall architecture for the development of the global structure of a single software system by grouping the artifacts into subsystems.
Then the composition of subsytems is done with the support of general knowledge.
Finally we get our architectural description.

4. Procedure of Use case Driven Method :

First the client provides information specifications or requirement specifications.
Based on the client's information, use case model is made which describes both domain model and business model.
From the use case model the architecturally significant use cases are selected and use-case realizations are created.
Then the use-case realizations are supported by the knowledge on the corresponding artifacts and the general knowledge.
The output of this function is the concept Analysis & Design Models, which represents the identified artifacts after use-case realizations.
The analysis and design models are then grouped into packages.
Finally, the definition of interfaces between these packages results in the concept Architecture Description while being supported by general knowledge.
