Data inconsistency occurs when similar data is kept in different formats in more than one file. When this happens, information technology is important to match the data between files. Sometimes, files duplicate some information. When information like names and addresses are duplicated, it may lead to a compromise in data integrity.
What Is Data Integrity?
Data integrity occurs when the data in a database are consistent. Every arrangement relies on data integrity to ensure that they take reliable and accurate information. The data must also exist consistent with real-earth events.
When an organisation has stiff data integrity, the information represents real information. For example, information technology provides authentic information about a patient'southward accost and telephone number after they have moved.
Information Inconsistency Is Caused Past Redundancy
Redundant data is a problem because it tin can create unreliable data. One person may change the value in one file but non in some other file. This is a problem for companies that rely on accurate data.
Allow's say that a hospital has a system for file processing, simply several files for one patient are kept separately. If a professional changes the patient'south address in ane file but not in any others, the patient's bill, or insurance information could exist sent to the wrong destination. If you lot do not have the right telephone number on each file, y'all may discover yourself running into bug regarding which one to call.
How to Prevent Data Redundancy
Several methods can prevent data redundancy. For i, planning better structures for databases can prevent information from being nowadays in several files. In some cases, this is non possible. Normalizing a database is the next footstep. The procedure involves cleaning up the tables in the database.
The goal of preventing data redundancy is to ensure that information is in one place. It is not scattered throughout the database.
Sometimes an organization tries to normalize a database. They may not be able to clean up all the redundant data. When this happens, i may see a information anomaly.
Man Error
Sometimes, the organization needs to pace in and ensure that employees are trained properly. Information input tin can exist tricky, and untrained employees may non realize they are adding new information rather than irresolute quondam information.
How to Prevent Data Inconsistency
People approach information inconsistency in two ways. One way to fix the problem is through central semantic storage. This requires a lot of logging and storing rules. It as well involves creating a central expanse for information. The process tin can be difficult.
You can also use the primary reference shop approach. This process seeks to centralize the information. This means that there are strict rules nearly where the database stores information. The goal of this approach is to have more control over important data. Information technology may crave more resources than other methods.
Every organization wants its data to exist accurate and reliable. From insurance companies to tech companies, organizations all across the country demand to know the information they take collected is useful.
