Businesses, scientists, and researchers worldwide employ databases to continue track of information. Databases can be useful for everything from sending a postcard to all of your customers to discovering results in a scientific study.

Even so, data becomes less valuable when it is not reliable. Data inconsistency is one of the most common threats to reliable data. What is data inconsistency, and what problems does it cause?

What Is Data Inconsistency?

To use data, it has to be recorded in a format that makes it easy to read and track. Many businesses use electronic databases to track and store big batches of data. Especially for large businesses or all-encompassing studies, the size of the information to track may be much larger than tin can fit in i file or even on 1 figurer.

Data inconsistencies arise when the data that should be in 1 database ends upwardly in multiple files, each with a dissimilar version of the same information. The same entries could exist in the database multiple times. There may be multiple versions of the aforementioned database where one version includes fields that another version is missing. The result is a set of data that is not accurate or like shooting fish in a barrel to use.

Although technology makes data easier to track, improper use of engineering science is frequently the culprit for data inconsistency. Several people can interact to make the aforementioned data set, but it is important to make certain that all of the people edit the aforementioned file. Whatsoever changes have to be visible to all other collaborators in real-time. There likewise needs to be a consistent, reliable source of data to enter into the database. Information technology would crusade information inconsistencies if different individuals were pulling data from the aforementioned sources. Information technology would also atomic number 82 to redundant and inconsistent data if i or more than of the individuals working on the databases could not see or continue rails of the updates made by others.

For example, suppose that four coworkers are creating a database of the customer e-mail addresses for a large business. Some emails come up from a sales funnel. Others come from a coupon opt-in, and the rest of the emails come from three different contests. If one coworker is updating a file that is only saved to his hard bulldoze, the rest of the team volition not see the changes he makes. The final database will be missing any electronic mail addresses he finds.

If the rest of the employees add together to a database stored online where changes are visible in existent-fourth dimension, that’s a pace in the right direction, but what nearly their data sources? It is possible that some customers signed upwardly for all 3 contests. Simply using a list of emails from each contest would result in some email addresses existence listed multiple times. The database needs programming rules to prevent duplicate entries.

Whether logistical or technological, the bug that can upshot in data inconsistencies accept easy solutions. Nevertheless, y’all have to be aware of the potential problems and develop a programme that works. For large sets of data that multiple people work on, information technology takes careful planning to remove data inconsistencies from the process.

Why Is Data Inconsistency a Problem?

Here’s a real-life example of data inconsistency on a much smaller scale. Suppose Jack, Ann, and Sheldon are all working on a group projection, and they need to write an essay together. They worked together in the library, and they needed to finish the last page of the essay over the weekend. Jack typed upwards the original file on his laptop. He emails the file to his project partners as a Discussion document.

Jack continues editing his Word document after emailing his partners. Ann uploads the information to a Google Doc, which she and Sheldon edit in real-time. At the end of the weekend, at that place were two different papers. Jack has one version of the paper that he worked on. Ann and Sheldon have another version of the paper. Both papers have three of the same pages, just the fourth page is unlike. At present, both of the documents are missing data. The group volition have to meet again to decide which data from both papers to employ.

Data inconsistency is far more serious in business organization and science than doing a piffling extra piece of work on a newspaper. Data inconsistency is a huge problem because people brand decisions based on data. Inaccurate data results in poor decision-making. Suppose that a database collects responses in a study on a new medicine. If inconsistencies count ane,000 positive results twice, a medicine that does not actually work could go to market. If a company uses an inconsistent database to mail catalogs to customers, the company could waste product thousands of dollars sending multiple catalogs to the same household.

How to Forestall Information Inconsistencies

There is a term in technology that says, “garbage in, garbage out.” If you put bad information into a database, the database tin only requite you bad information in return. One of the simplest means to prevent data inconsistencies is to build rules into the spreadsheet or other database software that is being used to track data.

Data inconsistencies usually result in one of two problems: duplicate or missing data. Planning and project management can prevent missing data. For instance, a business can set a policy that all employees use the same online software that updates in real-fourth dimension. This will prevent employees from saving dozens of iterations of the aforementioned database on their own computers. Database rules aid identify data inconsistencies and remove them before they influence results and decisions. Manufacture-specific software has highly-sophisticated methods of recognizing duplicates. Fifty-fifty the most basic spreadsheet software can be programmed to detect errors.

Understanding what information inconsistencies are is the central to understanding and preventing them. As the saying goes, an ounce of prevention is worth a pound of cure. It is much easier to fix the causes of data inconsistency than to improve the wide variety of problems resulting from information technology.
