It is often indicated that an Information System in a Bank does not have quality data due to the large number of data sources. This can sometimes happen because data is considered incorrect. This incorrect data can be due to errors in data entry, unsustainable system schemes due to inherited systems, overlapping data, etc. So it takes the Data Cleansing stage. Data Cleansing is used to convert data that is deemed incorrect into quality data required at the data mining stage. For that, we need an appropriate method to perform the Data Cleansing process. From the narrative above, state and briefly explain how to determine quality data? And what are the indications? What are the steps taken to perform Data Cleansing?
