Logical Design and Physical Network Design Logical Design logical design is a conceptual, abstract design. At this stage, the system analysts do not deal with the physical implementation details; they are only concerned with defining the types of information that the organization needs to access through the networks (Hoffer, George, and Valacich, 2002). The process of logical design involves arranging data into a series of logical relationships, which are referred as entities and attributes. An entity represents information about a place, object, events, and concepts. In relational databases, an entity often maps to a table. An attribute is a component of an entity and helps define the uniqueness of the entity. In relational databases, an attribute maps to a column. One output of the logical design is a set of entities and attributes corresponding to fact tables and dimension tables. Another output of mapping is operational data from the source into subject-oriented...
In this approach, the system analysts identify business subjects or fields of data, define relationships between business subjects, and name the attributes for each subject.During the PDIOO procedure one has to define main deliverables and related actions with a direct connection to the additional value and advantage for the customer network. For instance, understanding business objectives, usage features, and network necessitieshelps a person avoid pointlesselevations and network redesigns, thus reducing the time taken to introduce fresh services in the network. Planning Phase During the planning period one can test the significance of the design for future
Network Design Consultation Design recommended for the client The requirement of the client of the small billing business shall deserve a tailored system for his network design. This compels for network similar for a small office management process. Shall has a variety of the components suited in their places. The network shall facilitate the process of file sharing, internet access, connection to a networked printer, maintain a basic, secure environment and facilitate
Sometimes, only network design enhancements are needed for existing networks that are still functional. Characterizing the network infrastructure is the next step in designing a new network. To be able to develop a network map, different methods must be used. It is possible to figure out the architecture of the existing network by locating the cabling in the physical environment (Oppenheimer, 1998). The accessibility to major hosts and storage spaces
This is not to say that collusion is taking place in this process, of course, but it is to say that it is much easier for companies such as Network Design with substantive bidding experience and the credentials to match to secure government contracts than it is for an up-and-comer with little or no relevant experience in either area. The use of the Capability Maturity Model is clearly congruent
Network Standards A Brief Look Since 1995 This is a research paper that focuses on network standards and protocols that involve strategies in management. Leadership strategies cannot handle the need for network standards to handle billions of users and user generated applications. Therefore management strategies are more appropriate. Furthermore the history of network standards shows layering through the OSI models follows a management approach vs. A leadership approach. In the OSI model, there
Network Security: Past, Present and Future The work of Curtin (2007) states that a network is defined as "any set of interlinking lines resembling a net, a network of roads -- an interconnected system, a network of alliances." Quite simply a computer network is a system of computers that are interconnected. There are seven layers of communication types identified by the International Standards Organization (ISO) Open Systems Interconnect (OSI) Reference Model
