In software development and product management, a user story is an informal, natural language description of features of a software system. They are written from the perspective of an end user or user of a system , and may be recorded on index cards, Post-it notes , or digitally in specific management software. [ 1 ]
Use case points (UCP or UCPs) is a software estimation technique used to forecast the software size for software development projects. UCP is used when the Unified Modeling Language (UML) and Rational Unified Process (RUP) methodologies are being used for the software design and development.
High quality of database design: In evolutionary database design, the developer makes small changes to the database schema in an incremental manner and this achieves a highly optimized database schema. Handling change: In a traditional database approach, a lot of time is spent in remodeling and restructuring the database when the requirements ...
Experience architecture (XA) is the art of articulating a clear user story/journey through an information architecture, interaction design and experience design that an end user navigates across products and services offered by the client or as intended by the designer. This visual representation is intended not only to highlight the systems ...
The logical data structure is converted into a physical architecture in terms of database structures. The exact structure of the functions and how they are implemented is specified. The physical data structure is optimized where necessary to meet size and performance requirements.
Other software sizing methods include Use Case-based software sizing, which relies on counting the number and characteristics of use cases found in a piece of software, and COSMIC functional size measurement, which addresses sizing software that has a very limited amount of stored data such as 'process control' and 'real time' systems.
It is mostly used in Scrum terminology where the work is planned in terms of features (or stories). For example, as a very basic approach, a software project may consist of three layers (or components): Data access layer (bottom) Business logic layer (middle) User interface layer (top) In this common approach, a vertical slice means a bit of ...
The Fowler style can also be viewed as a simplified variant of the Cockburn template. This variant is called a user story. Alistair Cockburn stated: [27] Think of a User Story as a Use Case at 2 bits of precision. Bit 1 of precision names the goal of the use case, and Bit 2 adds the main scenario.
