MELJUN CORTES MIS Back End MELJUN CORTES MIS Back End Presentation Transcript

  • Information Management System back end MELJUN CORTES MELJUN P. CORTES MELJUN P. CORTES
  • Back End, in the context of a computer system, refers to a node or software program that provides services to a front end. The front end typically interfaces with users directly while the back end may communicate with other systems such as databases and other systems. MELJUN P. CORTES MELJUN P. CORTES
  • Front-end and back-end are generalized terms that refer to the initial and the end stages of a process. The front-end is responsible for collecting input in various forms from the user and processing it to conform to a specification the back-end can use. The front-end is a kind of interface between the user and the back-end. MELJUN P. CORTES MELJUN P. CORTES
  • Front-end and back-end are terms used to characterize program interfaces and services relative to the initial user of these interfaces and services. (The "user" may be a human being or a program.) A "front-end" application is one that application users interact with directly. A "backend" application or program serves indirectly in support of the front-end services, usually by being closer to the required resource or having the capability to communicate with the required resource. The back-end application may interact directly with the front-end or, perhaps more typically, is a program called from an intermediate program that mediates front-end and back-end activities. MELJUN P. CORTES MELJUN P. CORTES
  • In compilers, the front-end translates a computer programming source language into an intermediate representation, and the back-end works with the internal representation to produce code in a computer output language. The back-end usually optimizes to produce code that runs faster. The front-end/back-end distinction can separate the parser section that deals with source code and the back-end that does code generation and optimization; some designs (such as GCC) offer the choice between multiple front-ends (parsing different source languages) and/or multiple backends (generating code for different target processors) MELJUN P. CORTES MELJUN P. CORTES
  • the final stage in a process or a task not apparent to the user. A common usage is in a compiler. A compiler's back-end generates machine language and performs optimizations specific to the machine's architecture. The term can also be used in the context of Open System Interconnect (OSI) network applications. A standard for layering of protocols (protocol stack) to implement it were was developed in 1978 as a framework for international standards in heterogeneous computer network architecture. The architecture is split between seven layers (lowest to highest): MELJUN P. CORTES MELJUN P. CORTES
  • 1. physical layer 2. data link layer 3. network layer 4. transport layer 5. session layer 6. presentation layer 7. application layer Generally each layer uses the layer immediately below it and provides a service to the layer above in a "back ended" way. MELJUN P. CORTES MELJUN P. CORTES
  • In the third generation of network computing, web servers perform back-end database computing where it's controlled and managed. But third generation computing takes advantage of the new interactive server/client interactive technology like Sun’s java and Microsoft’s Microsoft’s ActiveX/CORBA. Users on the client side want to interact in various ways such as perform sensitivity (what-if) type of analyses. MELJUN P. CORTES MELJUN P. CORTES
