A high-level design provides an overview of a system, product, service, or process. Such an overview helps supporting components be compatible to others. The highest-level design should briefly describe all platforms, systems, products, services, and processes that it depends on, and include any important changes that need to be made to them.
A formal description of a system, or a detailed plan of the system at component level to guide its implementation. [10] The composite of the design architectures for products and their life-cycle processes. [11] The structure of components, their interrelationships, and the principles and guidelines governing their design and evolution over ...
A design is the order of a system that connects individual components. Often, it can interact with other systems. Design is important to achieve high reliability, low cost, and good maintain-ability. [2] We can distinguish two types of program design phases: Architectural or high-level design; Detailed or low-level design
Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML) , Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE) .
A modular design can be characterized by functional partitioning into discrete scalable and reusable modules, rigorous use of well-defined modular interfaces, and making use of industry standards for interfaces. In this context modularity is at the component level, and has a single dimension, component slottability.
Component-based software engineering (CBSE), also called component-based development (CBD), is a style of software engineering that aims to construct a software system from components that are loosely-coupled and reusable. This emphasizes the separation of concerns among components. [1] [2]
Architecture focuses on the partitioning of major regions of functionality into high level components, where they will physically or virtually reside, what off-the-shelf components may be employed effectively, in general what interfaces each component will expose, what protocols will be employed between them, and what practices and high level ...
Architecture/Design – Overview of software. Includes relations to an environment and construction principles to be used in design of software components. Technical – Documentation of code, algorithms, interfaces, and APIs. End user – Manuals for the end-user, system administrators and support staff.
