![]() Whether it’s for 3D modeling, documentation or even creating a program spreadsheet, computers are well entrenched within the profession. These days, nearly every architect uses a computer. Here we discuss the introduction and System properties of architectural design, Software architectural models, Advantages, disadvantages.This article was originally published on ArchSmarter. This is a guide to Architectural Design in Software Engineering. Here, in this article, we have discussed the architectural design process and its advantages and disadvantages. Avoiding critical features inside the small components leads to more communication among the components which in turn degrades the performance.Īrchitectural design is a very important phase and is a multi-step process which represents the data structures, program structure, interface characteristic, and procedural details.Use of large components may improve the performance as large components include all the related properties and function into one component but it reduces the maintainability as it becomes difficult to modify and replace the large component.Architectural design re-use the components, the use of redundant components improves the availability but makes the security of the system difficult to handle.The software architecture that is the output of the architectural design process can be reused across a range of the system.ĭisadvantages of Architectural Design in Software Engineering Architectural design is used to analyze whether the system will be able to meet its non-functional requirements or not. It is used as a support or roadmap in the discussion with system stakeholders Architectural design works as a tool for stakeholder communication.It provides a comparison between different Software architecture.Īdvantages of Architectural Design in Software Engineering ![]() It usually follows the top-down approach. They are derived from the application domain rather than from existing systems. Reference models: These models provide information regarding the class of the system.This type of model usually follows a bottom-up approach. Generic model: These models are abstractions derived from a number of real systems and encapsulated the characteristics of these systems.Relationships type of architectural model represent models such as data flow diagram to represent the component interrelationship.Īrchitectural design models are application domain-specific and the most common two types of domain-specific models are:.Interface type of architectural model represents the interface of the components.Distribution type of architectural model represents how the component is distributed across various computers.Dynamic type of architectural process model represents the process structure of the system.Static type of architectural structural model represents the major system components.To document the architectural design process, architectural models are used How can architectural design be analyzed?.What control strategy must be used to control the operation of the components in the system?.How can the system be decomposed into modules?.How can software architecture be documented?.Which architectural styles are suitable for the proposed system?.Is there a generic application architecture procedure that can be used which can act as a template for the proposed system that is being designed and developed?.Which approach can be used to structure the system?.How can the system be distributed across the network?.But still, there are some common decisions that should be taken care of in any design process are as follows In software engineering, the architectural design process differs as the system differs depending upon the type of system being developed. Availability: Architectural design process includes redundant components and corresponding functions for handling the occurrence of any type of errors.Safety: Avoid critical functionalities in small components of the system.Consider the components in a manner so that it is easy to change them over time according to the new requirements and build the software with the flexibility to change or maintain. Maintainability: Architectural design process uses easily modifiable and replaceable components.This is possible by using large components instead of small and fine-grained components. The performance of a system can be improved by avoiding critical operations and reducing communication between components. Performance: It is nothing but a meantime taken between request and response of the page.The architectural design process uses a layered architecture with critical assets in the innermost layers. Security: The system is secured against malicious users by encryption or any other security measures.
