A data anomaly is a fault in the database. It occurs when there's a deviation from the normal pattern of the database due to a glitch or error. In most cases, normalization helps correct anomalies. But it's common for several to slip through the cracks.

Anomalies are often a byproduct of poor planning or database structure. Many types of anomalies can occur. However, the most common include redundancies, inconsistencies due to updates, issues due to incomplete data inserts and accidental deletions. Data anomaly detection software can help avoid these problems. But are they necessary?

Why You Need Data Anomaly Detection Software

Anomalies can be relatively minor at first. But eventually, they can cause massive issues later.

Businesses need accurate and reliable data to function. A seemingly small data anomaly can lead to significant and costly issues downstream. For example, imagine how much it would cost to fix an error that caused you to order parts in the wrong size. We're talking thousands, if not millions, of dollars down the drain.

That's an extreme example, but it can happen from one small anomaly. Data reliability is important. You can't afford to have issues with how much businesses rely on data for everything from sales to everyday operations.

Anomalies can cause systems to break and force teams to work with outdated or incorrect information. Fixing those issues takes time and resources while pulling focus on tasks that matter.

How Does Anomaly Detection Work?

Anomaly detection software can work in many different ways. At its core, these systems monitor data quality to spot issues before they cause headaches. For example, you can set thresholds and set various monitor types. Configure alert tolerances and the software will notify you where and when anomalies arise.

The best anomaly detection platforms leverage advanced machine learning technology. They can learn about your data environment through historical metadata. This process helps provide smarter alerts while accounting for seasonal trends and feedback from the teams that use your data most.

It doesn't matter what industry you're in or how your organization uses data. Having anomaly detection is a game-changer that improves data resiliency and reliability.
