Architecture Advantage CSP’s architecture emphasizes its use of an N-tier application structure, which is a multi-layered design pattern widely adopted for providing greater separation of concerns within a software system. Here’s a closer look at what this entails: N-tier Architecture: This is a client-server architecture in which the presentation, the application processing, and the data management are logically separated. "N" refers to any number of separate tiers (layers). Stacked Groups of System Components: In such an architecture, system components are organized into distinct layers or tiers, each with specific responsibilities. For instance, you might have a data access layer, a business logic layer, and a presentation layer. Isolation in Layers: Each layer is isolated from the others, meaning that the internal processes or operations of one layer are independent of those in another layer. This isolation aids in maintaining the system's organization and can improve maintainability. Independence of Layers: The most significant advantage of this tiered setup is that changes to one layer can be made independently of others. For instance, you can update the database system (data layer) without altering the business logic or the user interface. Here's what each tier typically represents in an N-tier architecture: Presentation Tier: The topmost level of the application is the user interface (UI). This layer displays information related to services available on a website or a web application. Business Logic Tier (Application Tier): The central tier of the architecture, where information collected from the presentation tier is processed - often against other data - using business logic, a set of business rules. Data Tier: The bottom layer which is the database itself. CRUD (Create, Read, Update, Delete) operations are executed in this tier. By implementing an N-tier architecture, Advantage CSP can offer greater flexibility for development and scaling. Developers can upgrade or modify each layer without affecting the others, provided the defined interfaces between layers are maintained. This modularity makes it easier to manage large applications, improves the potential for code reuse, and can allow for better testing practices.
