A Brief Assessment Of The Data Modeling Tutorial

By Alyce Powell


Computer systems are used for the conversion of raw facts and figures into some meaningful information. The figures are collected from various sources and then categorized. These facts act as input for the computer systems. Information is then outputted after the processing. This information acts a pivot for decision making processes. The data modeling tutorial breaks down the process of data conversion.

Different software tools are used for the manipulation of figures. The software applications used by the researcher depend on the type of the end result intended and the type of figures at hand. The definition of processes is done at the onset immediately after the categorization stage. The categories also define the scope of operation within the different levels.

Different models are employed in the manipulation of figures. This depends of the amount of figures at hand and the type of operation that must be performed. The basic models are used for manipulating the simple and straight forward sets of figures. The system requires get more complicated as the figure sets get complicated. Most of the assessments are carried out at the logical level.

Raw facts and figures are collected from various points. In research work, the data forms a very integral part of research methodology. The facts collected are organized into different categories depending on the source and the intended use. The categorization of figures enables the researcher understand the nature of operations that are likely to be performed on a particular piece of information. This also forms a basis of processing.

The management of resources is very important. The methodologies used for collection of facts and figures aim at making the best use of available resources. Standards are set and the framework of operation must be implemented. Semi-formal models help understand the organization of facts within a certain framework. The integration of various tools also has to be carried out within a certain framework to protect the integrity of information.

Strategic modeling is carried out on facts that are of very strategic importance to the organizations in question. This includes the facts and figures that are to be used at the top management level of an organization. They are very critical in decision making. The managers rely on this information when making important decisions about the organizations. There is another set of figures that is not very delicate. This is used at the middle management level of different organizations.

The manipulation processes are broken down in number of ways. Logical diagrams are the most common tools used for explaining the operations. The framework is broken down for the end users since the framework is too conceptual for them. The logical diagrams explain the stages that the raw figures are taken through for processing. In some cases, some schematics can be used.

A data modeling tutorial may apply the top-down approach. This happens when explaining a very complicated concept. Such concepts have to be broken down in stages. The down-up approach is used when explaining very simple operations within a computer system.
