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 ...
For the Online Shopping System, the total estimated size to develop the software is 125.06 Use Case Points. Now that the size of the project is known, the total effort for the project can be estimated. For the Online Shopping System example, 28 man hours per use case point will be used. Estimated Effort = UCP x Hours/UCP
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]
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.
Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...
The method includes the identification and weighting of user recognizable inputs, outputs and data stores. The size value is then available for use in conjunction with numerous measures to quantify and to evaluate software delivery and performance (development cost per function point; delivered defects per function point; function points per ...
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database.
To find the right level of component granularity, software architects have to continuously iterate their component designs with developers. Architects need to take into account user requirements, responsibilities and architectural characteristics. [3]
