Kwame Aidoo (654644)Data Modelling Process
Data modelling is the process of simplifying data by applying certain formal techniques to reach a final
alternative/decision. This is a step-to-step process that is taken in decision making. These steps
include;
Identifying the problem; Identifying a problem at hand is the first step we take when making decisions.
Without a problem, there is no process to make a final decision.
An example of a rational decision-making process is sentencing an offender to years in jail in a case of
rape. The sentencing decision goes through these decision-making steps until an alternate decision is
made, before the convict is given a number of years in jail. The problem identified is the rape case.
Collecting information
After the problem has been identified, it is brought before the court, where the jury and the judge
establish the decision criteria; by collecting evidences provided and analysing information from the
offender and victim to find key info/data that they will provide. For example, some evidences may be
the bruises on the victim’s body, if the girl got pregnant after the incident or any STD’s got transmitted.
Weighing, the evidence, Identifying the alternatives and choosing from the alternatives is done all
together. With solid evidence, an alternative decision is identified and chosen.
After the evidences and key information has been identified and collected, they are weighed and
analysed to see how the evidences communicate with each other in the case. When they evidences
are weighed, we get to know the strong evidences and the weak evidences. The evidence needs to
link with each other to bring out the actual picture of the case. This is also the stage which decides the
level of degree of the crime committed.
In the case of rape, there are categories these evidences fall into. Most at times, spreadsheet
applications are used to help the in making these decisions; that is, sentencing an offender. The
spreadsheet is scripted and coded into an algorithm where the categories are listed, and the evidences
are assigned unto the categories they’re in. A conditional formula is encoded into the algorithm to
analyse and generate the level of degree of the crime and also, the number of years the victim will be
getting.
