Data cleansing is a necessary but often overlooked part of working with any data set. It is an essential step in the data analysis process that prepares data for further processing. Data cleansing is the process of detecting and correcting (or removing) corrupt or inaccurate records from a database. This helps ensure data integrity and accuracy, as well as maintaining the trustworthiness of the data.
What Is The Data Cleansing Process?
Data cleansing involves both manual and automated processes to identify, correct and delete corrupt or inaccurate records from a database. It is important to note that data cleaning is not the same as data analysis. Data analysis is the process of making sense of data by performing mathematical or statistical operations on it, while data cleaning focuses on the more mundane task of ensuring that the data is accurate and up-to-date.
Data cleansing requires a thorough understanding of the data and the data structure. The data needs to be checked for accuracy and corrected or removed if necessary. This includes checking for inconsistencies, duplicate values, incorrect values, and missing values. The data also needs to be formatted correctly and standardized to ensure that it is readable and meaningful.
