The spiral model is used by reputable companies such as IBM, Microsoft, Patni Computers and Tata Consultancy where large projects are involved.
You keep going back to where you started until you get it right.
The Java standard library refers to the set of dynamically loadable libraries that Java applications can call at run time. This is because the Java platform is not dependent on the specific operating system.
Iterative model is used when tight market deadlines make completion of a comprehensive software product impossible, but a limited version must be introduced in order to meet competitive or business pressure; a set of core product or system requirements are well understood, but the details of product or system extensions have yet to be defined. In these and above situations, a process model is required that has been explicitly designed to accommodate a product that evolves over time. Iterative model provides the best help in such situation.
1. As a way of facilitating discussion about the system design. A high-level architectural view of a system is useful for communication with system stakeholders and project planning because it is not cluttered with detail. Stakeholders can relate to it and understand an abstract view of the system. They can then discuss the system as a whole without being confused by detail. The architectural model identifies the key components that are to be developed so managers can start assigning people to plan the development of these systems.2. As a way of documenting an architecture that has been designed. The aim here is to produce a complete system model that shows the different components in a system, their interfaces, and their connections. The argument for this is that such a detailed architectural description makes it easier to understand and evolve the system.
Spiral Model.........
its too complicated
Prototype model is one that is used for refinement of requirements . Prototype model of library management system gives an outlook of how the software product will look like.
Spiral model was developed by Dr. Barry Boehm . This model was mainly used to evaluate and resolve risks in the software project.
The spiral model is used by reputable companies such as IBM, Microsoft, Patni Computers and Tata Consultancy where large projects are involved.
Library Domain Model describes main classes and relationships which could be used during analysis phase to better understand domain area for Integrated Library System (ILS), also known as a Library Management System (LMS).See link below as an example of Class diagram for Library Management System.
Im pretty sure that is an API.
dewey decimal system

The Dewey Decimal System is used in most public libraries .
Traditionally, spiral bevel gear milling machines from Gleason Works are used for milling of spiral bevel gears. However, less expensive and more popular universal milling machines have been recently used for milling. Correct 3-d CAD model of the gear tooth is the key element for milling a spiral bevel gear on a CNC milling machine. The CAD model of the gear tooth is produced on special "SPIRAL BEVEL GEAR SOFTWARE".
