| 1 | IR Multimedia Systems | multimedia information retrieval means the process of searching for and finding multimedia documents; the corresponding research field is concerned with building multimedia search engines |
| 2 | OOP | Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which can contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods) |
| 3 | Operating systems | is system software that manages computer hardware, software resources, and provides common services for computer programs |
| 4 | Quality Attribute | is a measurable or testable property of a system that is used to indicate how well the system satisfies the needs of its stakeholders |
| 5 | SOLID | In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable |
For each quality attribute it provides name, description, motivation (rationale for selecting), measurable metrics and priorities from business and architecture points of view.
The metrics show whether a particular quality attribute is achieved or not.
The components where metric is measured is noted as well.
| Name | Explanation | Motivation for selecting | Metrics | Business value | Architecture viewpoint |
|---|---|---|---|---|---|
| Availability | TBD | TBD | TBD | TBD | TBD |
| Conceptual Integrity | The software shall be decomposed into well-structured modules according to functional decomposition | TBD | The code review process shall be established to make sure the modules are structured according to functional decomposition | Low | Middle |
| Interoperability | The proposed solution shall have the ability to be integrated with online and offline Multimedia IR systems in the common way | The system shall be able to be integrated to any IR Multimedia Systems with a high level of easiness | The code review process shall be defined to make sure the OOP, SOLID principles and MVC pattern are going to be used | High | High |
| Learnability | The system shall have the UI allowing users to quickly become familiar with it and be able to make good use of all their features and capabilities.The user guideline and working instruction shall be available | It is required to help the user to get familiar with the system | TBD | High | High |
| Maintainability | The system shall be able to undergo changes with a high level of easiness | The following changes might happen frequently: - changes applied to the UI like adding new screen; - adding new multimedia formats to support; - new metadata search criteria to handle. - new offline or online IR Multimedia Systems can be easily integrated | The code review process shall be defined to make sure the OOP, SOLID principles and MVC pattern are going to be used | Middle | High |
| Manageability | The system shall be monitorable via UI and logging.The system shall support debugging as well | It is applied to easily support the systems operations in the fields | The code review process shall be established to make sure the Each component shall use UI and logging component: - to save any important events - to disk via logging; - to show the progress of processing in UI; - to show any important events - to user in UI; - to provide the user with an ability to cancel the processing in UI | Middle | High |
| Performance | The same as for the whole system, the UI shall respond in less than 1 second. As there might be time-consuming jobs, it shall show the current progress for such operations to provide the user with a status | It is applied to support great UX | The regular performance test shall be performed to check it | High | Low |
| Portability | The software shall support all wide known desktop/laptop operating systems - Windows, MacOS, Linux Ubuntu with the latest update.No support of the web or mobile platform required | Those platforms are selected to cover about 100% of desktop user | TBD | High | Middle |
| Reusability | The system components shall be usable in other functionality or other flows | It is applied for deduplication of implementation and to reduce the implementation time spent) | A common library is going to be created to keep the following functions used by several components: - To work with configuration; - Logging functions; - Common UI functions; | Middle | High |
| Reliability | If the system is going to fail during an operation, it shall report the operation status to user with error description and roll back all applied changes for this operation | TBD | TBD | High | High |
| Scalability | TBD | TBD | TBD | TBD | TBD |
| Security | Each multimedia file shall have “read only” attribute set up after processing on Windows | It is applied not to allow it easily change multimedia after processing | Functional test shall be created to check if all multimedia files after processing are marked with “read only” flag | Low | Low |
| Supportability | During abnormal function, the software shall provide the information to find and to solve the issues via prompting user in UI and saving detailed information into the log file. Also it has: - to show the progress of processing in UI; - to show any important events to user in UI; - to provide the user with an ability to cancel the processing in UI. The user shall be able to change a log level as configurable parameter | It is applied to easily support the systems operations in the fields and for monitoring. TBD - Add a description for Administration tools and specific deployment aspects | TBD | High | Middle |
| Testability | TBD | TBD | TBD | TBD | TBD |
| Traceability | The system code shall be traceable to the requirements | To make possible to measure the product readiness | TBD | Low | Low |
| Usability | The system shall be intuitive, easy to localize (to support multiple time zones, languages, etc.) and globalize. In addition, the installation package must be provided for each supportable platform to increase the usability of product | TBD | TBD | High | Middle |
