Here, the presentation (user interface), processing (business functionality) and data are separated into separate distinct entities. Now software’s are available to perform almost every commercial task. So here is my take on the evolution of software architecture with an italian food perspective! In this architecture, remote procedure calls or standard query language statements are being used by clients to communicate with servers. Evolutionary architectures are appealing because change has historically been difficult to anticipate and expensive to retrofit. This system also helped in reducing the traffic as the only necessary set of information is being mounted. People started splitting the applications into different components so that multiple teams can independently work. This reduces the network traffic by supplying relevant query response to the client instead of the total file transfer.
