XML, JSON and AJAX


XML - Wikipedia

XML (eXtensible Markup Language) is a widely used format for storing and organizing data in a human-readable and machine-readable way. It uses tags to define elements and attributes to provide additional information about those elements. XML is flexible and can be customized to suit various needs, making it suitable for exchanging data between different systems and applications. It serves as a structured and self-descriptive language that allows information to be easily shared and processed by different software programs.


What is JSON? - YouTube


JSON (JavaScript Object Notation) is a lightweight and widely adopted data format for storing and transmitting information. It uses a simple and easy-to-read syntax that resembles key-value pairs in a dictionary. JSON represents data as objects, where each object consists of attributes (keys) and their corresponding values. It is commonly used for web APIs, configuration files, and data interchange between different systems. JSON is human-readable, machine-parseable, and can be easily understood and processed by a wide range of programming languages.

AJAX (Asynchronous JavaScript and XML) is a web development technique that allows web pages to update and exchange data with a server in the background without requiring a full page reload. It combines JavaScript, XML (although JSON is more commonly used today), and other web technologies to create a seamless and responsive user experience. With AJAX, you can send and receive data from a server without interrupting the user's interaction with the web page. This enables dynamic content updates, interactive features, and real-time data retrieval, making web applications more efficient, interactive, and user-friendly.

Mapping Interactions: The Use Case Model

Image
  Use case models are diagrammatic representations that describe how users (actors) interact with a system to achieve specific goals. They include use cases, which are scenarios that describe the steps taken by actors to accomplish a task. Use case models help in understanding the functional requirements of a system from the user's perspective. Key Components of Use Case Models: Actors: The individuals or entities that interact with the system. Use cases: Scenarios that describe the interactions between actors and the system. Relationships: The relationships between actors and use cases, such as association, generalization, and dependency. Benefits of Use Case Models: Defines system functionality: Clearly outlines the system's capabilities and how users will interact with it. Facilitates requirements gathering: Helps to identify and document user requirements. Supports system design: Provides a basis for designing the system's architecture and components. Aid...
