One of the architecture is the Two Tier Architecture, where a client is directly connected to a server. Copyright 2007-2018 by Interview Questions Answers. Usually, a server farm will have network switches and routers, these devices allow different parts of the server farm to communicate.

Interface is a concept where components interact between each other. That's all free as well! We are in an era where information technology plays a critical role in business applications, considered as an area an organization would highly invest in order to widen the opportunities available to compete the global market.

2-Tier and 3-Tier Client/Server Systems - The term client-server refers to a software architecture model consisting of two parts, client systems and server systems. In the client—server model, a server is more likely to be devoted to the task of serving.

Jomo Kenyatta This chapter defines distributed processing and how the Oracle Server and database applications work in a distributed processing environment. This material applies to almost every server of Oracle database system environment. Distributed Processing Distributed processing pdf arfhitecture use of more than one processor to divide clieng processing for an individual task. Client applications can concentrate on requesting input from users, requesting desired data from the server, and then analyzing and presenting this data using sedver display capabilities of the client workstation or the terminal for example, using graphics or spreadsheets. If the data is moved or distributed to other database servers, the application continues to function with little or no modification. As a result, it delivers the highest possible degree of archktecture, data integrity, and performance to its client applications. As your system grows, you can add multiple servers to distribute the database processing load throughout the network horizontally scaled. Alternatively, you can replace Oracle on a less powerful architecture, such as a microcomputer, with Oracle running on serevr minicomputer or mainframe, to take advantage eerver a larger system's performance vertically scaled. In either client, all data and applications are maintained with little or no modification, since Oracle is portable between systems. Network traffic is kept to a minimum because only the requests and the results are shipped over the network. A communications protocol is a set of standards, implemented in software, that govern the transmission of data across a network. If the underlying protocol changes, the database administrator makes some minor changes, while the application requires no modifications and will continue to function. The drivers also take replies from Oracle and package them for transmission to the tools via the same higher level downloads mechanism. This is all done independently of the network operating system.
