Study Notes

Architectural Design Decisions

Systems in the same domain often have similar architectures that reflect domain concepts
Application product lines are built around a core architecture with variants that satisfy particular customer requirements
Architectural patterns or 'styles' capture the essence of an architecture and can be instantiated in different ways

Evaluating Architectural Design

Evaluating an architectural design is difficult because the true test of an architecture is how well the system meets functional and non-functional requirements when it is in use
One way to evaluate is by comparing the design against reference architectures or generic architecture patterns

The Model-View-Controller (MVC) Architecture

The Model works directly with the database and does not deal with user interface or data processing
The View is the User Interface and contains HTML, CSS, JS, XML, or other markup languages to create a beautiful user interface
The Controller processes data after receiving a request from the View and before updating the database with the Model

Advantages and Disadvantages of MVC Architecture

Advantages:
- Fast development of the application
- Easy for multiple developers to collaborate and work together
- Easier to update the application
- Easier to debug as we have multiple levels properly written in the application
Disadvantages:
- Hard to understand the MVC architecture
- Must have strict rules on methods

The Client-Server Architecture

A distributed system model which shows how data and processing is distributed across a range of components
Can be implemented on a single computer
Set of stand-alone servers which provide specific services such as printing, data management, etc.
Set of clients which call on these services
Network which allows clients to access servers
Example: Gmail is a real client-server application, where the client is the Gmail Web Interface and the server is the Gmail Servers
