software portability requirements

Besides testability, a qualified software should be manageable after deployment. This paper organizes these dispersed portability concepts and terms into a standards-based reference framework of system portability requirements. Portability The effort required to move the software to a different target platform. Besides, even if whole application crashes, it may recover itself using backup hardware and data with fault tolerance approaches. Extensibility is the ability of software to add functionality without damaging system, so it may be thought of as a subset of flexibility. 3. 2. portability non functional requirements example. It refers to the process of testing the ease with which a computer software component or application can be moved from one environment to another, e.g. The problems can be to automate a part of a system, to correct shortcomings of an existing system, to control a device, and so on. Prior to HIPAA, no generally accepted set of security standards or general requirements for protecting health information existed in the health care industry. Reliability also stands for the integrity and consistency of the software even under high load conditions. The availability of this framework can facilitate the early identification and specification of the system portability NFR and their detailed allocation as specific portability functions to be handled by the specified allocation to hardware or software, or a specific combination of the two. … Source code should be tested with the most coverage and with the most efficient testing methods. Portability is the ability for the surviving spouse to use the deceased spouse’s unused estate and gift tax exclusion after the deceased spouse’s death. An example would be a … (can happen in assembly language) if one refers to local data in another module. https://www.guru99.com/non-functional-requirement-type-example.html There should always be B and even C, D. Plans. If the software can perform that type of processing, this is called horizontal scalability. Sathiya Kumar. A complete Software Requirement Specifications must be: 1. This can be performed by using encapsulation, interfaces, patterns, low coupling etc. PPortabilityortabilityis the degree to which software running on one platform can easily be converted to run on another Portability is hard to quantify, because it is hard to predict on what other platforms will the software be required to run Portability for a given software system can be enhanced by using languages, operating systems and tools that are universally available and standardized, such as FORTRAN, … Think of it like the map that points you to your finished product. It’s considered one of the initial stages of development. What are synonyms for Software portability? Synonyms for Software portability in Free Thesaurus. moving of any application from Windows 2000 to Windows 10. The more correct and useful documentation exists, the more maintainability can be performed. Portability is a characteristic attributed to a computer program if it can be used in an operating systems other than the one in which it was created without requiring major rework.Porting is the task of doing any work necessary to make the computer program run in the new environment. In other words, it could not be relied upon. Scalability is the ability for your program to gracefully meet the demand of stress caused … So it is relevant with availability and scalability. If you’ve ever dealt with non-functional requirements, you may know that different … The approach adopted in this research for the structure of this reference frame- work is based on the generic model of software proposed in the COSMIC-ISO 19761model, thereby allowing the functional size of the portability requirements allocated to software to be measured. Unambiguous 10. Optimal source/performance ratio must be aimed. Content coupling: if one directly references the contents of the other. False. A few seconds), and should not increase if transaction count increases. In the system requirements phase, the non-functional requirements (NFR) are often captured only generically at a fairly high level, and they do not yet include the levels of detail necessary for the system engineers to allocate them as specific functionalities to be handled either by the software or the hardware, or a specific combination of the two. NPAC Software Releases. Are very important in this case. asked May 22 '14 at 17:13. McCall's Quality factors 2. The measurement is most commonly person-months or % of modules that need changing. Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. All possible types of security leaks should be considered, otherwise one day only one attack may crash your whole applicaion and whole company. It may be monitored for e.g. A software requirement can be of 3 types: Functional requirements; Non-functional requirements; Domain requirements; Functional Requirements: These are the requirements that the end user specifically demands as basic facilities that the system should offer. Note: for the definition of Non-Functional requirements in general see the article “Non-Functional Requirements”. Common coupling: access to global data. For the purposes of this article an Availability Requirement is any requirement that is not a functional, data or process requirement concerned with defining the periods when the solution can be u… a software system, software module, requirements- or design document) supports testing in a given test context. asked Feb 19 '15 at 9:20. zzzzz. There is no one standard definition of an Availability Non-Functional Requirement. 6. Scalability. Traceable 11. If you can perform both paralelly, it is the best. The measurement is often expressed in MTBF (mean time between failures). In this sense, portability is also related with flexibility Testability and Manageability Quality software requires quality testing. 5. So, more people can make use of it. IEEE defines software requirements specification as, 'a document that clearly and precisely describes each of the essential requirements (functions, performance, design constraints and quality attributes) of the software and the external interfaces.Each requirement is defined in such a way that its achievement can be objectively verified by a prescribed method, for example, inspection. This principle is true of all non-functional requirements. Software portability Portability in high-level computer programming is the usability of the same software in different environments. A computer software application is considered portable to a new environment if the effort required to adapt it to the new environment is within reasonable limits. Usability and Accessability User interfaces are the only visible parts of software according to the viewpoint of user. Software designed to run on both Windows 7 and Macintosh operating systems. A preffered scalable system should suit both of these methods. Availability, Robustness, Fault Tolerance and Reliability: A robust software should not lose its availabilty even in most failure states. Of course more hardware may be added for handling increasing user transaction, but the architecture should not change while doing this. IEEE defines requirement as (1) A condition or capability needed by a user to solve a problem or achieve an objective. This may include authorization and authentication techniques, network attack protections, data encryption and so on. Portability is becoming universally recognized as a desirable attribute for most software products, and porting is a recognized technique for extending the value and life of a software unit. A number of portability-related concepts are dispersed throughout the ECSS, IEEE-830, ISO 9126, ISO 24765, and ISO 2382-1 standards to describe, at varying levels of detail, the various types of candidate portability requirements at the system, software, and hardware levels. IEEE defines software requirements specification as, 'a document that clearly and precisely describes each of the essential requirements (functions, performance, design constraints and quality attributes) of the software and the external interfaces.Each requirement is defined in such a way that its achievement can be objectively verified by a prescribed method, for example, inspection.
