Data redundancy occurs once the same piece of data is stored in two or more separate locations and is a typical occurrence in numerous businesses. As more companies are moving away native siloed data to making use of a main repository to save information, they room finding that their database is filled v inconsistent duplicates of the same entry. Back it can be an overwhelming to mediate — or even benefit from — duplicate data entries, understanding just how to reduce and also track data redundancy properly can assist mitigate permanent inconsistency issues for your business. 

How does data redundancy occur?

Sometimes data redundancy wake up by accident while various other times it is intentional. Accidental data redundancy deserve to be the an outcome of a facility process or inefficient coding when intentional data redundancy deserve to be supplied to defend data and ensure consistency — just by leveraging the multiple events of data for catastrophe recovery and also quality checks.

You are watching: Exists when different versions of the same data appear in different places

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

Understanding database matches file-based data redundancy 

Data redundancy have the right to be uncovered in a database, which is an organized collection that structured data that’s stored by a computer system or the cloud. A retailer may have a database to monitor the commodities they stock. If the exact same product gets gone into twice by mistake, data redundancy takes place. 

The very same retailer may keep customer papers in a file storage system. If a client purchases indigenous the company an ext than once, their name might be entered multiple times. Duplicate entries the the customer surname is thought about redundant data.

Regardless of even if it is data redundancy occurs in a database or in a file storage system, it can be problematic. Fortunately, data replication can aid prevent data redundancy by save the very same data in lot of locations. With data replication, companies can ensure consistency and also receive the details they require at any type of time. 

Top 4 advantages of data redundancy 

Although data redundancy sounds favor a negative event, there are countless organizations the can benefit from this procedure when that intentionally built into daily operations. 

1. Alternate data backup method

Backing up data involves creating compressed and also encrypted version of data and also storing the in a computer system system or the cloud. Data redundancy uses an extra class of protection and also reinforces the back-up by replicating data to an additional system. It’s often an advantage when suppliers incorporate data redundancy into their disaster recovery plans. 

2. Better data security 

Data defense relates come protecting data, in a database or a file storage system, indigenous unwanted activities such together cyberattacks or data breaches. Having the same data stored in 2 or an ext separate places can safeguard an organization in the occasion of a cyberattack or breach — an occasion which can result in shed time and also money, and also a damaged reputation. 

3. Faster data accessibility and updates

When data is redundant, employees gain fast accessibility and quick updates because the vital information is accessible on many systems. This is an especially important because that customer service-based establishments whose customers expect promptness and efficiency. 

4. Improved data reliability 

Data that is trusted is complete and accurate. Organizations have the right to use data redundancy to twin check data and also confirm it’s correct and completed in complete — a necessity when interacting with customers, vendors, interior staff, and also others. 

Watch out for data redundancy disadvantages

Although there are noteworthy advantages of intentional data redundancy, over there are likewise several far-ranging drawbacks when organizations are unaware of its presence. 

Possible data inconsistency

Data redundancy occurs once the same item of data exist in many places, whereas data inconsistency is when the exact same data exist in various formats in many tables. Unfortunately, data redundancy can reason data inconsistency, which can administer a agency with unreliable and/or meaningless information. 

Increase in data corruption

Data corruption is when data i do not care damaged as a an outcome of errors in writing, reading, storage, or processing. When the exact same data fields are repeated in a database or file storage system, data corruption arises. If a paper gets corrupted, because that example, and an employee make the efforts to open up it, they may get an error message and not be able to complete your task. 

Increase in database size

Data redundancy may boost the size and also complexity the a database — making it an ext of a difficulty to maintain. A bigger database can likewise lead come longer pack times and a an excellent deal the headaches and frustrations because that employees as they’ll should spend much more time completing day-to-day tasks. 

Increase in cost

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

How to reduce data redundancy 

Fortunately, the is possible to minimize unintentional instances of data redundancy that regularly lead to operational and financial problems. 

Master data

Master data is a solitary source the common service data the is shared throughout several applications or systems. Although grasp data go not alleviate the events of data redundancy, it allows companies to occupational around and accept a specific level the data redundancy. This is due to the fact that the use of master data ensures the in the occasion a data piece changes, an organization only demands to upgrade one piece of data. In this case, redundant data is repeatedly updated and also provides the exact same information.

Database normalization 

Database normalization is the procedure of effectively organizing data in a database so that redundant data is eliminated. This procedure can certain that all of a this firm data looks and reads an in similar way across every records. Through implementing data normalization, an organization standardizes data fields such together customer names, addresses, and also phone numbers. 

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

When it involves normalizing data, each agency has their own unique collection of criteria. Therefore, what one organization believes to be “normal,” might not be “normal” for another organization. For instance, one firm may desire to normalize the state or province field v two digits, while another may like the complete name. Regardless, database normalization have the right to be the vital to reducing data redundancy throughout any company. 

Efficient data redundancy usage cases

Efficient data redundancy is possible. Plenty of organizations choose home advancement companies, actual estate agencies, and companies concentrated on customer interactions have customer relationship administration (CRM) systems. 

When a CRM mechanism is integrated with one more business software like an bookkeeping software the combines customer and financial data, redundant manual data is eliminated, top to an ext insightful reports and also improved client service. 

Database administration systems are likewise used in a range of organizations. They get direction indigenous a database administrator (DBA) and permit the system to load, retrieve, or adjust existing data indigenous the systems. Database administration systems adhere to the rules of normalization, which reduces data redundancy. 

Hospitals, education homes, and other medical care entities usage database monitoring systems to generate reports that administer useful details for physicians and other employees. When data redundancy is efficient and also does not result in data inconsistency, these systems deserve to alert healthcare providers of rises in denial case rates, exactly how successful a specific medication is, and other important pieces of information.
