The main purpose of data cleansing or data scrubbing is to improve the quality of data. It is possible that the data is outdated and not relevant today and needs to be up dated. Or it may be that because the existing data was compiled from different sources, it has no consistency. While certain portions of the data may be totally missing, other contents may be repeated with data duplication.
Thus data cleansing is the process of removing or correcting data from a data base that could be incorrect, incomplete, not in the proper format or even duplicated. Data cleaning can be a time consuming process and quite tedious. Professional data cleaning companies offer services online and frequently use data cleaning tools for removing specific errors and problems in the data. Thus outsourcing your entire data cleaning project to professional and experienced BPO companies can be advantageous in many ways.
Some aspects of the data cleaning process include:
- Removing outdated data
- Removing duplicated data
- Identifying missing data
- Removing invalid data
- Data validation
- Data enrichment with better relevant data
- Organizing data into proper format
