Distributed Programming

Distributed programming falls out of the use of computers to form networks. Distributed programming typically falls into one of several basic categories:

• Client/Server? -- Smart client code contacts the server for data, then formats and displays it to the user. Input at the client is commited back to the server when it represents a permanent change.
• [3 Tier Distribution]? -- Three tier systems move the client intelligence to a middle tier so that stateless clients can be used. This simplifies application deployment. Most web applications are 3-Tier.
• [N-Tier Distribution]? -- N-Tier refers typically to web applications which further forward their requests to other enterprise services. This type of application is the one most responsible for the success of [Application Servers]?.
• [Remote Procedure Call]? -- This distribution system maps function calls to the network.
• [Distributed Object]? -- Systems like CORBA?, Microsoft [DCOM D/COM]?, [Java RMI]? and others, try to map [Object Oriented]? design to the network
• [Loosely Coupled]? -- Loosely coupled systems are ones that communicate through intermediate documents that are typically human readable. Examples include XML, HTML, SGML, X.500, and EDI.
