The process to achieve this needs knowledge asfar as the guidelines, rules, procedures ability to manipulate andorganize is concerned. Hence becoming suitable for a given task needsto be performed. All theserules,data collection, relationships long with procedures get their home inthe application of knowledge.

Concerningthe above, informationin the databasemust have the following characteristics: the data must be accurateinformation that is correctis always error free. Forinstance,the spelling of names is correct. Second, the data must be completeinformation that is full is the one that bears all the relevant factsregarding a particulartopic about students.
