In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.
The chapter introduces the topic. It discusses the "beginning" and the "meaning" of a novel, the socio-cultural conventions/rules and the methodology of linking the individual events, which may be used in this narrative form, as well as the interactions of these elements. As a special case the autobiographical novel (it's me, who tells) is ...
Robustness analysis reduces the ambiguity in use case descriptions, by ensuring that they are written in the context of an accompanying domain model. This process makes the use cases much easier to design, test and estimate. The ICONIX Process is described in the book Use Case Driven Object Modeling with UML: Theory and Practice.
A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
Google Books (previously known as Google Book Search, Google Print, and by its code-name Project Ocean) [1] is a service from Google that searches the full text of books and magazines that Google has scanned, converted to text using optical character recognition (OCR), and stored in its digital database.

A use case survey is a list of names and perhaps brief descriptions of use cases associated with a system, component, or other logical or physical entity. This artifact is short and inexpensive to produce, and possibly advantageous over similar software development tools , depending on the needs of the project and analyst.
