What is Modifiability?
Modifiability is the degree of ease at which changes can be made to a system, and the flexibility with which the system adapts to such changes.
What is availability scenario?
Availability general scenarios. An example availability scenario, derived from the general scenario of Figure 4.2 by instantiating each of the parts, is “An unanticipated external message is received by a process during normal operation.
What can stated about Modifiability?
What can stated about Modifiability? Explanation: Modifiability is always considered largely architectural, Modifiability can be determined by how functionality is divided.
What is quality scenario?
Quality scenarios document required quality attributes. They help to describe required or desired qualities of a system, in pragmatic and informal manner, yet making the abstract notion of “quality” concrete and tangible. Event/stimulus: Any condition or event arriving at the system.
What is action Modifiability?
1. To change in form or character; alter. 2.
What are Modifiability tactics?
A modifiability tactic is an architecture transformation that improves the modifiability of that ar- chitecture. We are applying the approach we sketched for performance to modifiability.
How do you increase the modifiability of a system?
The use of layering within components to reduce intracomponent coupling is a technique for increasing component modifiability. Layering within the component separates the component’s different technical responsibilities.
Is availability a quality attribute?
Availability is part of reliability and is expressed as the ratio of the available system time to the total working time. Important indicators for this attribute are: Availability. Planned downtime.
Which of the following can be considered regarding client and server?
Which of the following can be considered regarding client and server? Explanation: Client and server is an architectural style.
Which lines depict that architecture defines constraints on an implementation?
3. Which lines depict that architecture defines constraints on an implementation? Explanation: An implementation exhibits an architecture if it conforms to the structural decisions described by the architecture, the implementation must be divided into prescribed components.
What is quality attribute scenario list the parts of scenario with an example?
Table 4.2. Modifiability General Scenario Generation
| Portion of Scenario | Possible Values |
|---|---|
| Source | End user, developer, system administrator |
| Stimulus | Wishes to add/delete/modify/vary functionality, quality attribute, capacity |
| Artifact | System user interface, platform, environment; system that interoperates with target system |
How do you maintain Modifiability?
We identify five such tactics.
- Maintain semantic coherence. Semantic coherence refers to the relationships among responsibilities in a module.
- Anticipate expected changes.
- Generalize the module.
- Limit possible options.
What is modifiability?
Modifiability is a quality attribute that refers to the ability of a given system to accommodates changes. The paper addresses and analyzes the internal potential problems due to modifiability using scenario-based analysis.
What is modmodifiability in software testing?
Modifiability is also a design quality attribute of a system and is closely related to maintainability and cost of the software system as a modification of an element at any part of the system can have an adverse effect on other elements in the system.
What are modifiability effects in software engineering?
These are termed as “modifiability effects” which are the consequences of change in the architecture of the system. An ideal software system would be a one that can accommodate these changes and deal with these consequences in a reasonable manner that minimizes the cost of change.
Can scenario-based analysis solve internal potential problems due to modifiability?
The paper addresses and analyzes the internal potential problems due to modifiability using scenario-based analysis. A structured polyglot model for scenario based architectural analysis is presented and analyzed with respect to applying modifiability tactics.
