Client/server is the combination of three major technologies: Relational database management systems (RDBMSs), networks, and client interfaces. Clients execute specific local tasks with local resources. Servers provide shared resources and fulfill broad tasks. Communication enables definition and completion of full work processes. Client/Server software Infrastructure With competing paradigms-SQL databases, TP monitors, groupware, and distributed objects-the middleware that connects clients to servers has grown dauntingly complex. Client /server is the combination of three major technologies: relational DBMS, networks, and client interface (usually GUI/PC based). Each element contributes to the overall platform with very specific roles but is independent of the others in performing its functions. Advantages of the Client/Server Environment Client/server is an open system. The advantages of this environment include: Interoperability, Data integrity, Scalability, Accessibility, Performance, Security, Adaptability, and Affordability. Client/Server Architectures The client/server software architecture is a versatile, message-based modular infrastructure intended to improve usability, flexibility, interoperability, and scalability as compared to a centralized, mainframe, time-sharing computing. A client is defined as a requester of services and a server is defined as the provider of services. A single machine can be both a client and a server depending on the software configuration. As a result of the limitations of file-sharing architectures, the client/server architecture emerged. This approach introduced a database server to replace the file server. Distributed Client/Server Architectures Distributed client/server systems serve environments with mixtures of heterogeneous computers and networks, with users and objects everywhere. Distributed Object Database Management Systems (ODBMSs) provide a mec…
