Webinar Description
Data preparation is the process of cleaning, standardizing and enriching raw data to make it ready for use in analytics and data science. It is said that most data analysts and data scientists spend more than 80% of their time finding, cleansing and organizing data.
Data cleaning is the process that involves altering existing records to detect and to correct (or remove) corrupt or inaccurate records from a record set, table, or database.
In this webinar, Jan Willem will explain the key objectives of data cleansing and the purpose of the operations typically used in a data cleansing process.
