Distributed programming falls out of the use of computers to form networks. Distributed programming typically falls into one
of several basic categories:
* [[client server |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.
