interoperability quality attribute scenario

Different system modules should work on different operating system platforms, different databases, and protocol conditions. Source of stimulus. QUALITY ATTRIBUTE SCENARIOS A quality attribute scenario is a quality-attribute-specific requirement. 1. Performance – shows the response of the system to performing certain actions for a certain period of time. The quality attributes provide the means for measuring the fitness and suitability of a product. Stimulus source 3. quality attributes that are of particular concern to them. ... For the above scenario what quality attributes are necessary? Each is potentially but not necessarily relevant to the system you are concerned with. Artifact 4. ... A quality attribute scenario has six parts, shown in the schematic: Source of Stimulus: the entity generating the stimulus. Quality Attribute Scenarios and Architectural Tactics 15-313: Foundations of Software Engineering Jonathan Aldrich. 9 September 2008 15-313: Foundations of Software Eng ineering Software Architecture 2 Source [BCK03] Bass, Clements, and Kazman. Stimulus – a condition that needs to be considered. It consists of six parts: 1. Interoperability. 2. Interoperability of one system to another should be easy for the product to exchange data or services with other systems. Software quality is the degree to which software possesses a desired combination of attributes (e.g., reliability, interoperability) [IEEE 1061]. This is some entity (a human, a computer system, or any other actuator) that generated the stimulus. A Quality Attribute Scenario is a quality-attribute-specific requirement. Finally, for each Quality Attribute refinement, the team documents at least one scenario that illustrates how the quality attribute requirement is being met. Interoperability is an attribute of the system or part of the system that is responsible for its operation and the transmission of data and its exchange with other external systems. The problems arise from software, not system engineering practices. Stimulus 2. Developing systematic ways to relate the software quality attributes of a system to the sys-tem’s architecture provides a sound basis … Quality Attribute Scenarios. Environment - what are the conditions when the stimulus occurs? b. Aqualityattributescenarioisaquality-attribute-specificrequirement.Itconsistsofsixparts. Artifact – what elements of … • The applications assign paramount importance to quality attributes such as timeliness, reliability, safety, interoperability, etc. Quality Attribute Scenarios Start with QA requirement statements Elaborate all quality attribute requirements as scenarios General –system independent Concrete –system specific As simple informal story-like descriptions … Or in a semiformal quality attribute scenario representation: 1. Software architecture has a profound affect on most qualities in one way or another and software quality attributes affect architecture. ... portability and interoperability. 4.4 Quality Attribute Scenarios in Practice. In the third and fourth week, you will learn how to correctly write quality attributes and quality attribute scenarios for a specific case. The truth is that qualities like interoperability, modifiability, ... are short stories that describe an interaction with the system that exercises a particular quality attribute. 12 software architecture quality attributes. Stimulus. The results of this exercise are documented in a utility tree (see Chapter 3 for a detailed discussion of the Quality Attribute utility tree) using the structure that we are now familiar with: Could be an actor, an actuator, a sensor, and so on. In the last week, you'll learn to describe your own patterns and tactics and see how they're used in an Android framework. General scenarios provide a framework for generating a large number of generic, system-independent, quality-attribute-specific scenarios.
