Information About Data Cleaning And Data Services

Information about Data Cleaning

A Brief History Of Data Cleaning

Data cleaning has long been considered an integral component of data analysis, yet its term was first coined in 1988 by John M. Chambers – a statistician and computer scientist.

Chambers was working at Bell Laboratories at the time on S language software packages used for statistical software development, when he introduced data cleaning as an important concept in his paper “Comprehensive Data Analysis System” by defining it as “the process of correcting or removing invalid values from a dataset.” Although the term became more widely utilized among data scientists and analysts later on, Chambers’ definition of what data cleaning is still relevant today.

Chambers stressed the significance of validating data before analysis began, noting that failure to address errors before analysis began could result in misleading or incorrect results. His concept remains relevant today: data cleaning remains essential in ensuring accuracy during analyses and creating trustworthy datasets; regardless of its application in an industry or model development process.

What is Data Cleansing?

Data cleansing (also referred to as data wrangling or cleaning) is an integral step in data analytics, serving to validate and prepare data prior to beginning analysis. While not a difficult process itself, data cleaning remains an integral component of it – typically consisting of identifying and correcting potentially incorrect or problematic records.

Rogue data refers to incomplete, incorrect, irrelevant, corrupted or incorrectly formatted data. One aspect of deduplication that’s often mentioned as part of this process is deduping. Deduping allows identical data points to be combined or eliminated – an essential part of deduping.

Why does deduping matter?

Data cleaning can be simplified: if it doesn’t exist, it won’t affect your analysis. As data analysis is often used for making business decisions, accurate results are crucial. While it might seem simpler to delete incomplete or inaccurate data points quickly and simply, doing so often leads to less reliable insights and increases reliability of insights gained from data analysis. Data cleansing aims at keeping as many points in as many analyses possible while increasing reliability of insights.

Data cleaning is of equal or greater significance than data analysis, serving a vital function in data governance and business housekeeping. Given the dynamic and ever-evolving nature of big data sources, keeping databases updated regularly is of vital importance for effective decision making and housekeeping purposes.

Why Is Data Cleansing Important?

Data analysis can often be summarized with the phrase, “garbage out, garbage in”. This maxim has become so well known among data analysts that its acronym, GIGO has come to symbolize it. What this phrase entails is simple – poor data quality will result in any analysis using it being unsuccessful regardless of any positive outcomes of data analytics processes.
