Data inconsistency occurs when similar data is kept in different formats in more than than one file. When this happens, information technology is of import to match the information between files. Sometimes, files indistinguishable some information. When information like names and addresses are duplicated, information technology may lead to a compromise in information integrity.

What Is Data Integrity?

Data integrity occurs when the information in a database are consistent. Every organization relies on information integrity to ensure that they have reliable and accurate information. The information must also exist consistent with real-world events.

When an arrangement has strong information integrity, the information represents real data. For instance, it provides accurate information most a patient'southward accost and phone number after they have moved.

Data Inconsistency Is Caused By Redundancy

Redundant data is a trouble considering it tin create unreliable information. One person may change the value in one file but non in another file. This is a trouble for companies that rely on accurate data.

Let'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's accost in one file just not in whatever others, the patient'south bill, or insurance information could be sent to the incorrect destination. If y'all exercise non have the right phone number on each file, you may find yourself running into problems regarding which one to call.

How to Forbid Information Redundancy

Several methods can forestall information redundancy. For one, planning better structures for databases can forbid data from existence present in several files. In some cases, this is not possible. Normalizing a database is the next stride. The process involves cleaning upwards the tables in the database.

The goal of preventing data back-up is to ensure that information is in one place. It is not scattered throughout the database.

Sometimes an organisation tries to normalize a database. They may not be able to make clean up all the redundant information. When this happens, one may run across a data anomaly.

Human being Error

Sometimes, the system needs to step in and ensure that employees are trained properly. Information input can be tricky, and untrained employees may non realize they are adding new data rather than changing old information.

How to Prevent Data Inconsistency

People approach information inconsistency in two ways. Ane fashion to set up the trouble is through primal semantic storage. This requires a lot of logging and storing rules. Information technology too involves creating a central area for information. The process tin can be difficult.

Yous tin can likewise utilize the master reference store approach. This process seeks to centralize the data. This means that there are strict rules nearly where the database stores information. The goal of this approach is to accept more command over important data. It may require more resources than other methods.

Every arrangement wants its information to be accurate and reliable. From insurance companies to tech companies, organizations all across the state need to know the data they accept collected is useful.
