Vorlesung 5

Question 1

What are the different dimensions of views in Software Architecture and how do they decompose?

Answer 1

Software (Structure & Behaviour), decomposes into: Data, Functions

Environment (Hardware & Infrastructure & Tools), decomposes into: Deployment and Activities

Technologies (used by the system)

Question 2

Software Architecture Concepts

Answer 2

Software Architecture divides into two principles: Abstraction & Separation of Concerns, which both together build the View-Based Architecture Documentation.

Question 3

Explain the principle of Abstraction for Software Architecture

Answer 3

PPT
____________________________________________________

Wikipedia: the process of removing physical, spatial, or temporal details[2] or attributes in the study of objects or systems to focus attention on details of greater importance;[3] it is similar in nature to the process of generalization;

Question 4

Explain the principle of Separation of Concerns

Answer 4

PPT

In computer science, separation of concerns (SoC) is a design principle for separating a computer program into distinct sections such that each section addresses a separate concern. A concern is a set of information that affects the code of a computer program.

Question 5

What is SPES?

Answer 5

Innovation alliance of 21 partners from industry and academia, which develops a platform for architecting Embedded Systems

Question 6

Fraunhofer Embedded Modelling Profile is based on which modelling languages?

Answer 6

Based on UML & SysML, continously improved during our projects

Question 7

How is the Modelling Profile for Embedded Systems Development constantly improved?

Answer 7

Architecture drivers like business drivers, quality requirements, functional requirements and constraints DRIVE architecture design like context, system functions, software entities and hardware & networks.

Question 8

Answer 8

Part of architecture design.

Includes: Humans, external systems, information flow, environment

Question 9

What is part of the functional view and of which design is it a part?

Answer 9

Part of architecture design.

Question 10

What is the logical view and of which design is it a part?

Answer 10

Part of architecture design.

First logical (structural) decomposition of the system.
Mapping of functions to logical components.

Question 11

What is the software view and of which design is it a part?

Answer 11

Part of architecture design.

Answer 12

Part of architecture design.

Included are:
Sensors, actuators, ECUs
Communication buses
Deployment of software components
Functional realization by hardware entities

Question 13

What is special about the Data Model

Answer 13

Defined in each view (logical, functional, software, …)

Traced to equivalences in other views

Question 14

What is the task of technologies in the context of architecture design?

Answer 14

Technologies are used to realize functional software, hardware, and data entities

Question 15
