Data redundancy occurs as soon as the same item of data is stored in 2 or more separate locations and is a typical occurrence in many businesses. As more companies are relocating away from siloed data to making use of a central repository to store information, they are finding the their database is filled through inconsistent duplicates the the very same entry. Although it can be an overwhelming to mediate — or even advantage from — duplicate data entries, understanding just how to reduce and track data redundancy efficiently can assist mitigate long-term inconsistency issues for your business. 

How walk data redundancy occur?

Sometimes data redundancy happens by accident while various other times the is intentional. Accidental data redundancy can be the result of a complex process or inefficient coding when intentional data redundancy have the right to be used to safeguard data and ensure consistency — just by leveraging the multiple occurrences of data for catastrophe recovery and quality checks.

You are watching: What do you call the elimination of redundant data?

If data redundancy is intentional, it’s essential to have a central field or space for the data. This enables you to quickly update all documents of redundancy data once necessary. When data redundancy isn’t purposeful, it deserve to lead come a variety of issues which we’ll discuss below.

Understanding database matches file-based data redundancy 

Data redundancy can be found in a database, i beg your pardon is an organized collection the structured data it is stored by a computer system or the cloud. A retailer may have actually a database to track the commodities they stock. If the very same product gets entered twice by mistake, data redundancy takes place. 

The exact same retailer might keep customer documents in a record storage system. If a client purchases indigenous the company more than once, your name might be gone into multiple times. Duplicate entries of the customer surname is thought about redundant data.

Regardless of even if it is data redundancy wake up in a database or in a document storage system, it can be problematic. Fortunately, data replication can help prevent data redundancy by storing the exact same data in multiple locations. V data replication, companies have the right to ensure consistency and also receive the info they need at any type of time. 

Top 4 benefits of data redundancy 

Although data redundancy sounds prefer a negative event, over there are numerous organizations the can benefit from this procedure when that intentionally built into everyday operations. 

1. Alternate data backup method

Backing increase data involves creating compressed and also encrypted execution of data and also storing the in a computer system system or the cloud. Data redundancy supplies an extra class of protection and reinforces the back-up by replicating data to second system. It’s frequently an benefit when providers incorporate data redundancy into their disaster recovery plans. 

2. Better data security 

Data protection relates come protecting data, in a database or a paper storage system, native unwanted activities such as cyberattacks or data breaches. Having actually the very same data save in two or more separate areas can safeguard an company in the occasion of a cyberattack or breach — an occasion which can an outcome in shed time and money, and a damaged reputation. 

3. Much faster data access and updates

When data is redundant, employees reap fast access and fast updates due to the fact that the essential information is obtainable on lot of systems. This is an especially important because that customer service-based establishments whose customers intend promptness and also efficiency. 

4. Enhanced data reliability 

Data the is reputable is complete and also accurate. Organizations deserve to use data redundancy to double check data and also confirm that correct and completed in complete — a requirement when communicating with customers, vendors, inner staff, and also others. 


Watch the end for data redundancy disadvantages

Although there room noteworthy advantages of knowingly data redundancy, there are additionally several significant drawbacks when establishments are unaware of its presence. 

Possible data inconsistency

Data redundancy occurs as soon as the same item of data exist in lot of places, conversely, data inconsistency is when the very same data exists in different formats in multiple tables. Unfortunately, data redundancy can cause data inconsistency, i beg your pardon can administer a agency with unreliable and/or meaningless information. 

Increase in data corruption

Data corruption is once data becomes damaged as a an outcome of errors in writing, reading, storage, or processing. When the exact same data fields are recurring in a database or paper storage system, data corruption arises. If a document gets corrupted, because that example, and an employee tries to open up it, lock may obtain an error message and not have the ability to complete your task. 

Increase in database size

Data redundancy may rise the size and also complexity the a database — make it an ext of a an obstacle to maintain. A larger database can additionally lead come longer fill times and a an excellent deal that headaches and also frustrations for employees together they’ll must spend more time completing daily tasks. 

Increase in cost

When more data is produced due come data redundancy, storage expenses suddenly increase. This have the right to be a serious worry for organizations who room trying to keep expenses low in order to increase profits and also meet your goals. In addition, implementing a database system deserve to become an ext expensive. 

How to alleviate data redundancy 

Fortunately, that is feasible to mitigate unintentional situations of data redundancy that often lead come operational and also financial problems. 

Master data

Master data is a solitary source that common organization data that is shared across several applications or systems. Although understand data does not minimize the occurrences of data redundancy, it enables companies to occupational around and also accept a details level of data redundancy. This is due to the fact that the usage of master data ensures the in the occasion a data item changes, an organization only requirements to update one piece of data. In this case, redundant data is repeatedly updated and provides the very same information.

Database normalization 

Database normalization is the process of effectively organizing data in a database so that redundant data is eliminated. This process can for sure that every one of a that company data looks and reads an in similar way across every records. By implementing data normalization, an company standardizes data fields such together customer names, addresses, and phone numbers. 

Normalizing data entails organizing the columns and tables that a database come make certain their dependencies are implemented correctly. The “normal form” refers to the collection of rule or normalizing data, and a database is recognized as “normalized” if it’s complimentary of delete, update, and also insert anomalies. 

When it comes to normalizing data, each firm has their own unique collection of criteria. Therefore, what one company believes to it is in “normal,” might not be “normal” for one more organization. Because that instance, one company may desire to normalize the state or district field v two digits, while an additional may like the complete name. Regardless, database normalization deserve to be the an essential to reduce data redundancy throughout any company. 

Efficient data redundancy use cases

Efficient data redundancy is possible. Numerous organizations choose home improvement companies, genuine estate agencies, and also companies concentrated on customer interactions have customer relationship administration (CRM) systems. 

When a CRM system is combined with an additional business software choose an audit software the combines customer and also financial data, redundant manual data is eliminated, leading to more insightful reports and improved customer service. 

Database administration systems are likewise used in a range of organizations. They receive direction native a database administrator (DBA) and permit the system to load, retrieve, or change existing data native the systems. Database management systems adhere come the rule of normalization, which reduces data redundancy. 

Hospitals, nursing homes, and also other medical care entities use database management systems to create reports that carry out useful information for physicians and other employees. When data redundancy is efficient and does not cause data inconsistency, these systems can alert health care providers that rises in denial case rates, how successful a details medication is, and also other vital pieces that information.
