Enforcement of a high-level statement of security policy may be difficult to discern when mapped through functional requirements to a myriad of possible security services and mechanisms in a highly complex, networked environment. A method for articulating network security functional requirements, and their fulfillment, is presented. Using this method, security in a quality of service framework ...

This paper describes work applying the Functional Requirements for Bibliographic Records (FRBR) model to music, as the basis for implementing a fully FRBRcompliant music digital library system. A detailed analysis of the FRBR and Functional Requirements for Authority Data (FRAD) entities and attributes is presented. The paper closes with a discussion of the ways in which FRBR is gaining adoptio...

The quality of data is often defined as “fitness for use”, i.e., the ability of a data collection to meet user requirements. The assessment of data quality dimensions should consider the degree to which data satisfy users’ needs. User expectations are clearly related to the selected information and at the same time the information can have different utilities depending on the type of user that ...

background: dyssynergic defecation disorder (dd) has recognized as the main factor for chronic functional constipation. this was a debilitating disease effective on diverse aspects of physical, psychological and social functions as well as patients’ quality of life generally. modern studies show positive impact of biofeedback therapy on dyssynergic defecation. this study was evaluated the effic...

Software architecture design is often based on architects intuition and previous experience. Little methodological support is available, but there are still no effective solutions to guide the architectural design. The most difficult activity is the transformation from non-functional requirement specification into software architecture. To achieve above things proposed “An Architectural Decisio...

Use case diagrams have proven quite helpful in requirements engineering, both for eliciting requirements and getting a better overview of requirements already stated. However, not all kinds of requirements are equally well supported by use case dagrams. They are good for functional requirements, but poorer at, e.g., securiq requirements, which ofren concentrate on what should not happen in the ...

In the last decade it became a common practice to formalise software requirements to improve the clarity of users’ expectations. In this work we build on the fact that functional requirements can be expressed in temporal logic and we propose new techniques that automatically detect flaws and suggest improvements of given requirements. Specifically, we describe and experimentally evaluate new ap...

The building of Web-based systems has often been ad hoc, lacking systematic development approaches, and quality control and assurance processes. In order to avoid the Web crisis, urge Web Engineering approaches for eliciting, developing and maintaining Web sites and Applications (WebApps) of required quality within budgetary constrains. To bridge this gap, one of our current concerns is assessi...

Model-driven techniques enable early prediction of the non-functional properties, such as performance, reliability, and costs, of a software architecture on a model basis. This allows to have an early assessment of the software architecture to avoid expensive redevelopments in late phases of the software development process if the non-functional requirements are not met. Even though there is us...

THIS ISSUE’S COLUMN reports on a presentation and papers from the 23rd International Working Conference on Requirements Engineering: Foundation for Software Quality (REFSQ 17). REFSQ aims to foster the creation of a strong European requirementsengineering community across industry and academia. Feedback and suggestions are welcome. In addition, if you try or adopt any of the practices included ...
