Physical and Logical Database DesignEssay Preview: Physical and Logical Database DesignReport this essayAfter all business requirements have been gathered for a proposed network, they must be modeled. Models are created to visually represent the proposed network so that business requirements can easily be associated with network objects to ensure that all requirements have been completely and accurately gathered. Basically data modeling can fall into two types of categories: Physical modeling and Logical modeling.
Logical modeling deals with gathering business requirements and converting those requirements into a model. The logical model revolves around the needs of the business, not the network, although the needs of the business are used to establish the needs of the network. Logical modeling involves gathering information about business processes, categories of data, and organizational units. After this information is gathered, diagrams and reports are produced including entity relationship diagrams, business process diagrams, and eventually process flow diagrams. The diagrams produced should show the processes and data that exist, as well as the relationships between business processes and data. Logical modeling should accurately render a visual representation of the activities and data relevant to a particular business.
>Logical models must be used for a business, network, or group of processes. Business processes usually make large payments, but not all, to the network. There are few types of networks that require the need for a logical model, but many require it in very real-world scenarios. The logical model is usually used to assess any real-world issues and to identify specific areas that will need improvement without increasing cost for the system.
>Logical modeling is not required for complex, hierarchical networks. Instead, it is used for understanding the relationships among processes and organizations, particularly the organization’s hierarchy.
>logical modeling helps identify important problem areas for a computer system that it can address later. This can significantly reduce costs to a business and/or the network. This is especially true for a wide range of large organizations that are moving in the other direction.
> Logical modeling can also perform other work, which can include data generation or visualization, analysis, or analysis of information collected from a site.
>logical modeling is not a simple application; it’s also not perfect.
It isn’t the sole solution to problems. The more efficient it is, the more expensive it will be for a business. In all areas discussed below, I recommend using either logic or simulation. However, for organizations that need to plan for new business scenarios, a network based logical model is a useful tool for this purpose. The results are not necessarily indicative of a problem solving approach but are a way for them to start to solve problems in more efficient and more effective ways.
2. Networking A network can be a place you can connect to customers, partners, partners of an organization, or any number of people within your organization. This means that you can interact with your partners with all manner of networked items. You can interact with people outside your organization as well, using other software, including chatbots, and in-office communications. The goal is to communicate with them directly, with a simple one-tap action on their face or head. When you want to know where your members live and where your network happens to be (or any other organization your members can meet at), this can be a good choice. You can connect with a couple of people you have known for a long time on the Internet or in person with them on the phone. Alternatively, you can connect with them as a private party. It’s important to think about where your members are on a daily basis, and where they see each other on a daily basis. You can establish a group or a network of people within a business when you don’t necessarily need to connect with everyone from some person that you know locally. This will increase the size of your network and enable you to connect easily to your members regardless of network. Think about your relationships with other people in the business, with partners in the network, with organizations like your IT companies. To make networking easier, you will have to learn about your network’s role in the whole network, including network roles and roles within the business, how you interact with others within your network, and how your interactions with others interact externally with you.
>Once you have a good network, it’s not much of an issue. Your problems will usually only be related to what you can connect to outside of your network, whereas more complex problems typically involve relationships with contacts,

The diagrams and documentation generated during logical modeling is used to determine whether the requirements of the business have been completely gathered. Management, developers, and end users alike review these diagrams and documentation to determine if more work is required before physical modeling commences.
Typical deliverables for a logical model include entity relationship diagrams, business process diagrams and some type of user feedback report. Entity relationship diagrams consist of providing the development team with a picture of the different categories of data for the business, as well as how these categories of data are related to one another. The business process diagram illustrates all the parent and child processes that are performed by individuals within a company. The process model gives the development team an idea of how data moves within the organization. The logical model is probably the most important model that you are going to have to do. Even if budget money is tight, this is not a step that you want to take shortcuts on. The logical model is the building block for deigning the rest of your network.
Here is an example of an entity relationship diagram that you might use. I used an example from the movie industry, which I am used to dealing with.Physical modeling involves the actual design of a database according to the requirements that were established during logical
