What is data preparation and who uses it?
Data preparation helps organisations to collect, cleanse, and consolidate their data into one, trustworthy file or table.
Business analysts and data stewards use data preparation tools to correct any human or machine input errors, remove duplicates, fill in incomplete data, and merge data from several sources or data formats.
This produces harmonised, standardised and enriched data, that is then analysed to inform business decisions.
Why is data preparation important?
Businesses need to have confidence in data to support strategic, operational, and financial decisions.
However, the increasing complexity of data is pressuring organisations to review their data preparation processes. Inconsistent and low-quality data compounds this challenge, making analytics and data mining slow and unreliable.
Preparing data sources has traditionally been an IT responsibility, but growing interest in data analytics is bringing non-IT personnel into data preparation. Self-service data preparation tools reduce the burden on IT, while ensuring data governance is part of the process.
