Note that the same "Viewpoints-driven" method as for logical architecture building is used for physical architecture definition. Outputs of this step consist of the selected physical architecture: components to be produced, including formalization of all viewpoints and the way they are taken into account in the components design.
The phenomenon of software architecture erosion was initially brought to light in 1992 by Perry and Wolf alongside their definition of software architecture. [3] Software architecture erosion may occur in each stage of the software development life cycle and has varying impacts on the development speed and the cost of maintenance.
It is intimately tied to many aspects of computer science: type systems for programming languages, the theory of transition systems, models of programming languages and the theory of programming language semantics. [6] Logic programming is a programming, database and knowledge representation paradigm that is based on formal logic. A logic ...
The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.
Object-oriented design is a method of design encompassing the process of object-oriented decomposition and a notation for depicting both logical and physical as well as state and dynamic models of the system under design. The software life cycle is typically divided up into stages, going from abstract descriptions of the problem, to designs ...
Domain-driven design (DDD) is a major software design approach, [1] focusing on modeling software to match a domain according to input from that domain's experts. [2] DDD is against the idea of having a single unified model; instead it divides a large system into bounded contexts, each of which have their own model.
In the field of programming a data transfer object (DTO [1] [2]) is an object that carries data between processes.The motivation for its use is that communication between processes is usually done resorting to remote interfaces (e.g., web services), where each call is an expensive operation. [2]
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
