Information inconsistency occurs when similar data is kept in dissimilar formats in more than 1 file. When this happens, it is important to match the information between files. Sometimes, files duplicate some data. 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 organization relies on data integrity to ensure that they have reliable and accurate data. The information must too be consistent with real-earth events.
When an organization has potent information integrity, the data represents real information. For example, it provides accurate information about a patient's address and telephone number later on they have moved.
Data Inconsistency Is Caused By Redundancy
Redundant data is a problem considering it can create unreliable information. 1 person may change the value in one file but not in some other file. This is a problem for companies that rely on accurate data.
Let'southward say that a infirmary has a arrangement for file processing, but several files for 1 patient are kept separately. If a professional person changes the patient's address in i file but non in any others, the patient'due south nib, or insurance information could be sent to the incorrect destination. If you exercise not have the right phone number on each file, you may discover yourself running into issues regarding which ane to telephone call.
How to Forbid Information Redundancy
Several methods can prevent data redundancy. For 1, planning improve structures for databases can prevent data from being present in several files. In some cases, this is not possible. Normalizing a database is the next step. The process involves cleaning up the tables in the database.
The goal of preventing data redundancy is to ensure that information is in ane identify. 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 information. When this happens, ane may run into a data anomaly.
Human Fault
Sometimes, the organization needs to step in and ensure that employees are trained properly. Information input tin be tricky, and untrained employees may non realize they are adding new data rather than irresolute old data.
How to Prevent Information Inconsistency
People approach data inconsistency in two ways. One way to fix the trouble is through central semantic storage. This requires a lot of logging and storing rules. It also involves creating a central area for data. The procedure can be difficult.
You tin also utilise the main reference shop approach. This process seeks to centralize the data. This means that there are strict rules about where the database stores data. The goal of this approach is to take more command over important information. It may require more resource than other methods.
Every arrangement wants its data to be authentic and reliable. From insurance companies to tech companies, organizations all across the country need to know the information they have collected is useful.
