Outsource Data Cleansing Services to NexGen
Data cleansing is essential for ensuring the quality of your database, as database decay is estimated at over 33% a year, you'll need to keep on top of your records. Companies move, people move, records are often incorrect or incomplete and hence it becomes necessary to improve and enhance databases through Data cleaning processes because as data becomes stagnant, the results obtained from using it also follows suit.

These data cleansing/scrubbing and enrichment services can guarantee that your databases - part and material files, item information, and product catalog files etc. - are current, precise and comprehensive. By outsourcing data cleansing process to NexGen, cost effective data enrichment is possible, which will enhance your business database and carter better data fetching, dispersion, visibility etc.
Data cleansing or data scrubbing is the act of observing and rectifying (or removing) corrupt or incorrect records from a record set, table, or database. Used mostly in databases, the term refers to recognizing incorrect, incomplete, irrelevant, inaccurate, etc. parts of the data and then replacing, altering or deleting this dirty data.
Often the existing data has no reliable format being derived from lots of sources. Or it contains redundant records/items and may have lost or incomplete descriptions. The data is normalized so that there is a common unit of measure for items in a class. For example. inches, feet, meters, etc. are all transformed to one unit of measure.
Data scrubbing also called data cleansing, is the process of modifying or removing data or data cleansing in a database that is unfinished, wrong, duplicated or improperly formatted. An organization in a data-intensive field like insurance, banking, telecommunications, retailing, or transportation might use a data scrubbing tool to methodically examine data for flaws by using rules, algorithms, and look-up tables.
Normally, a database scrubbing tool includes programs that are competent of correcting a number of certain types of mistakes, like adding lost zip codes or finding copy records. The use of a data scrubbing tool can save a database administrator valuable amount of time and can be fewer costly than removing errors manually.
The process of data cleansing
- Data Auditing: The data is inspected with the use of statistical methods to observe anomalies and contradictions. This ultimately gives a sign of the characteristics of the anomalies and their locations.
- Workflow Specification: The detection and reduction of anomalies is achieved by a sequence of operations on the data known as the workflow. It is particular after the process of auditing the data and is essential in achieving the end product of high quality data. In order to attain an appropriate workflow, the responsible reasons of the anomalies and errors in the data have to be closely looked. The implementation of the workflow should be efficient even on large sets of data which unavoidably poses a trade-off because the execution of a data cleansing operation can be computationally costly.
- Post-Processing and Controlling: : In some cases when data that could not be corrected throughout the execution of the workflow are manually corrected if possible. For more appropriate and clear data, the automatic processing is used in data cleansing and the data is reviewed to look the additional workflow in proper way.
