What is Data Cleansing?

In simple words, Data Cleansing refers to identifying the issues with data and fixing those issues. This definition is illuminating enough to highlight the crucial importance of Data Cleansing.

Nevertheless, little more elaboration would be good, for the readers are totally unaware of the subject. It would help them understand why every business needs data cleansing services.

Dirty Data

The size, numbers, formats, and types of data constantly evolve as the business flourishes. Multiple components cause the modifications in data, for example changing economic policies, amendments in hardware or software of machines or merging of supply-chain technologies. As a result, arise the needs of migrating, merging or combining the data from different sources. Therefore, we end up having “dirty data”.

Dirty data is the data that contains redundancies, includes duplicate records, or missing information. The operations of import and merge can result in this corrupt or dirty data. It is inevitable.

The Benefits of Data Cleansing

So data purification becomes indispensable. You need complete data health scan to ensure that data is correct, not old but updated and meaningful. Get the best Data Cleansing Service possible, or be ready for heavy losses.

Data cleansing comes with a lot of challenges, no matter the method is manual or automated. It may include correcting mismatches, ensuring the right order of columns and checking that data (such as date or currency) is in the same format. Moreover, you may have to enrich the data with supplementary information.

  1. Import data via API. You can also import it in .csv format, or any format required.
  2. Format data to match with destination database.
  3. Wherever possible, recreate the missing data.
