Abstract
In this essay, we hoped to see how the operational university job database systems perform badly, since there are a lot of signs that they fall short of data design fundamentals. Fortunately, we are able to choose a university employment support database(UESD) application as a candidate for our study. We have taken UESD system as it is and we have developed an enhanced version of the UESD system, which strictly followed the basic fundamentals in data modeling and named it as NewUESD system. Then, we have conducted a comparison to see how much UESD system is deviated from the standard balancedness found in NewUESD. From the perspective of data obesity, we computed how much UESD contains unnecessary data. The NewUESD contained no unnecessary data at all, which implies that it has only data that is necessary to form a data model. But the data obesity of UESD system is found to be more than 50%. Therefore, it is significantly higher, 37% higher in this case, than the obesity judged to be normal, which is 19% in NewUESD system.
