A data quality monitoring process monitors and ensures the quality of every data instance created, utilized, and maintained within an organization.

Companies strive to increase the accuracy of their operations, but errors will inevitably occur. If a mistake occurs, one of two things can happen – someone takes responsibility, rectifies the mistake, and ensures it doesn’t happen again. Unquestionably, the latter is the best option and promotes operational efficiency.

Companies can avoid potential issues from reoccurring in the future when it actively adjusts the processes or procedures linked with prior blunders; when problems are addressed proactively, the focus shifts from a quick fix to a long-term solution.

What is Data Quality?

What-is-Data-Quality

Data quality describes the state of every dataset. It evaluates objective elements like thoroughness, precision, and consistency. Additionally, it gauges more arbitrary elements, such as how well a dataset fits a specific purpose. Determining data quality can occasionally take time due to this subjective component.

A high-quality dataset can be used for the intended purpose, such as making an informed decision on future growth, making important financial decisions, or enhancing operations.

However, if data quality is poor, all these sectors suffer. It can lead to incorrect purchases, inefficient operations, and increased company expenses.

What is Data Quality Monitoring?

The exponential growth of data has made data quality monitoring essential for developing effective machine learning and data-driven systems. Moreover, 42 percent of data analysts who took part in Forrester’s online worldwide study on data trust and reliability say they spend over 40 percent of their time checking and evaluating the data.

Data quality is measured, evaluated, and enhanced to meet expectations and fulfill business needs. It may assist organizations in enhancing their data’s consistency, timeliness, and correctness.

There are many ways to evaluate data quality. But it solely depends on business needs. It includes data reviewing, testing, checking for accuracy or consistency, or auditing the data by regularly evaluating data quality with the data quality tools.

Since real-time deep learning and data analytics are so prevalent, the only way to validate data is to monitor its quality and assess it using a set of pertinent quality criteria.

Importance of Data Quality Monitoring

Importance-of-Data-Quality-Monitoring

If you wish to guarantee the accuracy and dependability of data, then you must implement data quality monitoring. Rogue data quality can lead to inaccurate decision-making, resource waste, and legal issues.

By monitoring data quality, organizations can detect and address issues before they have a large negative impact. The following are some advantages of data quality monitoring:

  1. Ensuring data completeness and correctness: Data quality monitoring ensures that all the information in the company’s database is accurate and satisfies all the criteria for “quality data.”
  2. Cost-cutting: When a corporation monitors its data, it can reduce the amount of money it could otherwise pay if a mistake or error arises with the data’s quality.
  3. Increasing client contentment: Clients are more likely to trust a corporation with excellent data than one with mediocre data management and a faulty database.
  4. Improving judgment: Greater decision-making occurs throughout an organization due to higher data quality. You can make decisions with greater confidence if you have access to more high-quality data.
  5. Enhancing operational effectiveness: – Organizations can lower the cost of finding and resolving incorrect data in their database by maintaining data quality levels. Additionally, businesses can prevent operational blunders and business process failures.

Implement Data Quality Monitoring

How-to-Implement-Data-Quality-Monitoring

The data quality framework procedure starts when the source data file (s) arrives on the SQL Server or any ETL Server. Following file detection, the Pre-Stage data quality requirement starts. Data Stewards get a notification when Pre-Stage rules acts and the results are ready for evaluation.

If the Pre-Stage data quality has errors, processing ends. The procedure continues only if the quality of the pre-stage data is satisfactory. Data is then added to the Stage Table.

Following this, the Post-Stage Data Integrity Rules are carried out, and it informs Data Stewards when the outcomes are ready for review. The downstream systems automatically publish a validated file for usage if there are NO Gating rules failures.

The Data Steward may opt to either end the cycle and request a fresh file from the source if any post-stage Gating criteria have failed, or they may ignore the error to upload data files for secondary processing.

A data quality data mart is necessary to implement the data quality monitoring framework.

The tables would provide the following capabilities in data quality:-

  • A table where all the predetermined Data Quality rules are kept. (DATA_QUALITY_RULE table)
  • A table that enables the ability to enable and disable rules and stores threshold proportions for every rule for its associated data domain. (DATA_QUALITY_RULE_EXECUTE table)
  • A table used as a results repository for Data Quality Rule Monitoring. It stores the outcomes of Data Quality Rules. (DATA_QUALITY_RULE_RESULTS)

Data Quality Indicators

In computer file systems, data quality indicators (DQIs) are identifiers used to capture the quality characteristics of the data. Since DQIS deals with time variables, their settings can affect which values are involved in a calculation and how it works.

Two significant database systems involve the usage of the DQI idea. According to the findings, DQI makes programming, storage management, and data processing control simpler.

Key Metrics: Data Quality

Data-Quality-Indicators

Here are some examples of indicators that often assist a business in tracking its efforts to improve data quality:

The proportion of mistakes in data

This kind of qualitative data measure is the most obvious. It enables monitoring the relationship between a data set’s size and the number of recognized errors, such as missing, imperfect, or redundant information. Data quality improves when anyone discovers lower error rates while the quantity of data remains the same or increases.

The proportion of empty values

Within data collection, the proportion of empty values is a straightforward approach to monitor data quality because empty values typically signal that information is missing or recorded in the incorrect field. Thus, You can track how many empty fields are in a data set.

The rate of data transformation errors

Data transformation issues, which include collecting information kept in one style and changing it to another, show data quality issues. You can learn more about the general quality of your data by calculating the frequency of data management operations that fail or take excessive time to complete.

The volume of dark data

You cannot use this data efficiently because of issues with data quality. You will likely have more issues with data quality.
