Data cleansing, also known as data cleaning or data scrubbing, is the process of identifying and correcting errors, inconsistencies, duplicates, and missing values in a dataset. Data cleansing is an essential step in data analysis, data mining, data integration, and data quality management. Data cleansing can improve the accuracy, completeness, validity, and reliability of the data, which can lead to better business insights and decision making.
Why is data cleansing important?
Data is one of the most valuable assets of any organisation. Data can provide insights into customer behaviour, market trends, operational efficiency, and competitive advantage. However, data is also prone to errors and inconsistencies due to various reasons, such as human error, system error, data entry error, data migration error, data integration error, and data decay. These errors and inconsistencies can affect the quality and usability of the data, which can result in poor business outcomes, such as:
– Loss of revenue and profit
– Loss of customer satisfaction and loyalty
– Loss of reputation and credibility
– Loss of competitive edge and market share
– Increased operational costs and risks
Therefore, data cleansing is important to ensure that the data is accurate, consistent, complete, and relevant for the intended purpose. Data cleansing can help organisations to:
– Enhance data quality and usability
– Increase data analysis efficiency and effectiveness
– Improve business performance and outcomes
– Reduce operational costs and risks
– Comply with regulatory standards and requirements
How to perform data cleansing?
Data cleansing can be performed manually or automatically using various tools and techniques. The general steps involved in data cleansing are:
– Define the data quality criteria and objectives
– Identify the data sources and scope
– Assess the current state of the data quality
– Detect and diagnose the data errors and issues
– Correct and resolve the data errors and issues
– Verify and validate the data quality improvement
– Monitor and maintain the data quality
What are the benefits of regular data cleansing?
Regular data cleansing can provide several benefits for organisations, such as:
– Improved data accuracy and consistency: Regular data cleansing can eliminate or reduce the errors and inconsistencies in the data, which can improve the accuracy and consistency of the data across different sources and systems.
– Improved data completeness and validity: Regular data cleansing can fill in or remove the missing or invalid values in the data, which can improve the completeness and validity of the data for the intended purpose.
– Improved data reliability and trustworthiness: Regular data cleansing can ensure that the data is up-to-date, relevant, and reliable for the intended use case, which can increase the trustworthiness of the data among the stakeholders.
– Improved business insights and decision making: Regular data cleansing can enhance the quality and usability of the data, which can enable more effective and efficient data analysis, which can lead to better business insights and decision making.
– Improved business performance and outcomes: Regular data cleansing can help organisations to achieve their business goals and objectives by providing accurate, consistent, complete, valid, reliable, and trustworthy data that can support their business strategies and actions.
– Reduced operational costs and risks: Regular data cleansing can help organisations to save time, money, resources, and efforts by avoiding or minimising the negative impacts of poor data quality on their business processes, operations, systems, products, services, customers, partners, regulators, etc.
Conclusion
Data cleansing is a vital process that can improve the quality and usability of the data, which can lead to better business insights and decision making.
