These issues make data preprocessing and analysis significantly more complicated. A query is simply a question put to a database management system, which then generates a subset of data in response. Data analysis is a process of inspecting, cleansing, transforming and modeling data with the goal of discovering useful information, informing conclusions and supporting decision-making. Therefore, the collected data contain many outliers and missing values. Data analysis is an internal arrangement function done by data analysts through presenting numbers and figures to management. Be fair in assessments and do not let territorial ownership play a part in the analysis.
