Object Methodology is a shortened form of object-oriented application development methodology. The goal of an object methodology is to use object technology to guide the development of a computer-based application. Object technology provides the basis for describing a problem and building a solution by using object models, thus ensuring a better understanding of the problem and faster development of a robust and flexible solution with significantly less maintenance cost.
The Object Modeling Technique covers analysis, design, and implementation phases of application development.
Extreme Programming (XP) is actually a deliberate and disciplined approach to software development. Developed in the mid 90's, it has already been proven at cost conscious companies like Bayerische Landesbank, Credit Swiss Life, DaimlerChrysler, First Union National Bank, Ford Motor Company and UBS.
XP is successful because it stresses customer satisfaction. The methodology is designed to deliver the software your customer needs when it is needed. XP empowers your developers to confidently respond to changing customer requirements, even late in the life cycle.
This methodology also emphasizes team work. Managers, customers, and developers are all part of a team dedicated to delivering quality software. XP implements a simple, yet effective way to enable groupware style development.
Object-Oriented Software engineering (OOSE) is a use-case-driven methodology. A use case represents a dialog between a user and the system. A use case is defined as " a particular form or pattern or example of usage, a scenario that begins with some user of the system initiating some transaction or sequence of interrelated events".
OOSE is divided into three phases:
Responsibility-Driven Design (RDD) is a dynamic methodology that emphasizes object behavior (responsibilities) and relationships with other objects (collaborations). RDD is a dynamic methodology because it finds the model objects on the basis of their behavior.
The RDD modeling process includes two phases:
Booch distinguishes the micro and macro elements of the development process. The micro development process serves as a framework for an iterative and incremental approach. The macro development process serves as the controlling framework for the micro process.
The Fusion method provides a systematic approach (method) to object-oriented software development. It is claimed to be a second-generation method, because it has integrated and extended existing approaches to provide a direct route from a requirements definition through to a program-language implementation.
The Unified Modeling Language (UML) is a language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.
VMT methodically and in a novel way combines techniques that have proven productive in other object methodologies.
