Presently I am working using single tier architecture. Now I am wanting to learn how to write code using 3 tier architecture. Please can you provide me with a simple example?
Wikipedia have a nice explanation: Multitier architecture:
'Three-tier' is a client-server architecture in which the user interface, functional process logic ("business rules"), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms.
Web development usage In the web development field, three-tier is often used to refer to websites, commonly electronic commerce websites, which are built using three tiers: A front end web server serving static content, and potentially some cached dynamic content. A middle dynamic content processing and generation level application server, for example Java EE, ASP.net, PHP platform. A back-end database, comprising both data sets and the database management system or RDBMS software that manages and provides access to the data.
