<div class='uawarticle'>The process of building information systems is detailed. The application part here must be separately handled and can be accomplished through the use of different programming approaches. This determines the functioning of the application which also requires data. This demands the creation of a database that will support the application. Developing and integrating this aspect requires prior knowledge. As such the need to understand some of these procedures can be addressed by a data modeling tutorial that is available on the internet.<br />
<br />
This exercise is all important because the application depends on the concept of the database. Therefore it becomes important to analyze all the requirements that are needed to support the business processes. This will be carried out based on three main perspectives.<br />
<br />
These views include the conceptual logical and physical aspects. The conceptual position shows the independent specifics about the data. These particulars are captured when the initial requirements by the user are being documented. This is achieved through sessions between the business stakeholders and the developers.<br />
<br />
These deliberations are important mainly because the business stakeholder requirements can be captured at this point. The general requirement is to accurately document the outcome from the discussions between the stakeholders and the developer. This basically denotes the conceptual aspect.<br />
<br />
Based on these deliberations or concepts the rules of business can eventually be derived. The developer must define the logic flow from the concepts as a requirement. Generally the types of inputs that are required at this point must be defined. As such the genuine documentation of the structures can be accomplished. This is the product of the conceptual view determined earlier on in the development process.<br />
<br />
After the logical view comes the physical perspective. Generally the tangible database can be derived at this point as determined by the logical view. Implementations like the table design are carried out here. Besides there are other considerations including the performance access and storage capacity needs that must be laid down at this point of development.<br />
<br />
Two main techniques are used to accomplish such a design process. Generally this development is viewed as a hierarchy with the parent or root at the top. At the base are the leaf nodes or child. Using this concept there is the top down and bottom up approaches. The former entails traversing the hierarchy starting at the parent down to the base or leaf nodes. Generally this implies having a whole perspective and eventually breaking down this into smaller views until one reaches the smallest of them which in this case can be equated to the leaf node. Obviously the bottom up is the reverse of this process where one begins with a unit aspect and builds on this until they have the global view.<br />
<br />
The elaborate nature of such an exercise requires some training. When there emerges such needs for <A href="http://www.modeloasis.com">data modeling tutorial</A> people can get this from the internet. It is also pertinent to incorporate other tools and techniques that can also be used. Dataflow diagrams (DFD) entity relationship diagrams (ERD) as well as object oriented patterns common within the unified modeling language (UML) are commonly used molding approaches. These are used at the various views to clearly decompose and understand the database development process. Therefore the ability to knowledgeably use these in the development process is likely to give forth high quality databases capable of fulfilling user needs.<br />
