Data Cleansing or Data Scrubbing are essentially the same processes comprising of the removal or modification of particularly undesirable data in a given database. This is a service offered by India Data Entry targeted at organizations with a pre-existing database or in the midst of database building.
Since the formation of a database may have a multitude of benefits for an organization, the snippets of data that is entered into the system likewise has to be of good quality. Good quality in terms of completeness, accuracy, correctness and error free; as the usefulness of a database is based on the quality of the data it holds.
Simply removing all the undesirable data may be the obvious solution but the downside is that the data will be lost to the database; possibly reducing the overall reliability of the information produced.
At India Data Entry we will use our developed procedures and software to attempt to rectify the data through smart modifications where possible. Modifications come in two forms one is where we are able to validate and correct values according to a given list by the client or by correcting based on pre-existing records with close correlation. Another type of data that we detect and cleanse from the database would be duplicate data entries.
Some of the methods adopted for Data Cleansing:
- Syntactic Analysis: Analysis of strings of data, detecting syntax errors
- Statistical Analysis: Analyzing statistical information, identifying anomalies and correction of correlative data
- Duplicate Elimination: Detecting and removal of repeat data entries
- Transformation: Changing format of data from one format into another
