The structure of an application with PAC. Presentation–abstraction–control (PAC) is a software architectural pattern.It is an interaction-oriented software architecture, and is somewhat similar to model–view–controller (MVC) in that it separates an interactive system into three types of components responsible for specific aspects of the application's functionality.
Technical co-ordinator: Responsible in designing the system architecture and control the technical quality of the project. Team leader: Leads their team and ensures that the team works effectively as a whole. Solution developer: Interpret the system requirements and model it including developing the deliverable codes and build the prototypes.
Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model Driven Architecture is a kind of domain engineering, and supports model-driven engineering of software systems.
Diagram that depicts the model–view–presenter (MVP) GUI design pattern. Model–view–presenter (MVP) is a derivation of the model–view–controller (MVC) architectural pattern, and is used mostly for building user interfaces. In MVP, the presenter assumes the functionality of the "middle-man". In MVP, all presentation logic is pushed to ...
Illustration of the 4+1 Architectural View Model. 4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
As software architecture design issues are intricate and interdependent, a knowledge gap in design reasoning can lead to incorrect software architecture design. [27] [34] Examples of knowledge management and communication activities include searching for design patterns, prototyping, asking experienced developers and architects, evaluating the ...
The expansion of the model to a dual-Vee concept is treated in reference. [3] As the V-model is publicly available many companies also use it. In project management it is a method comparable to PRINCE2 and describes methods for project management as well as methods for system development. The V-model, while rigid in process, can be very ...
Project plan – is a formal, approved document used to guide both project execution and project control. The primary uses of the project plan are to document planning assumptions and decisions, facilitate communication among stakeholders, and document approved scope, cost, and schedule baselines. A project plan may be summary or detailed. [10]
