Introduction to Data Quality Tools

In the Digital Era, the availability of big data facilitates new generation Industries to design novel business models and automate their business operations. It also helps them in inventing new technological solutions which in turn generate new business opportunities. Big data is generated from multiple sources like sensors, machines, social media, Web sites, and e-commerce portals. Data is the new oil and it is an asset to any organization and there are attempts to monetize the data. There are bound to be variations and inconsistencies in the data collected from so many heterogeneous sources. There should be a mechanism to correct the anomalies either at the source or post collection and to ensure high data quality. Unless the data is accurate, the insights we get from it will have no sense and we will not be able to make any meaningful comparisons and draw inference from it.

In this article let us study Data Quality tools and its features.

What is Data Quality Tool?

Before examining the data quality tool let’s dwell on data quality and understand its importance.

Data Quality

The success of any organization depends on the quality of the data collected, stored and used for deriving insights and the quality data forms the core part of any business and it is in the bottom layer in the information hierarchy. The information layer, Analytics layer (knowledge), Insights (wisdom) layers are on top of the data layer in the respective order mentioned (refer Fig-1).

Data quality can be defined as a characteristic that makes the data fit for its intended use and it can also be defined as the characteristic that makes the data to represent the true picture it is supposed to project. The above two definitions are in total contrast as the first one insists on the completion of the day-to-day transaction and the other one aims to achieve the end-to-end purpose for which the attributes are designed for.

For example, Employee master in payroll contains so many attributes, few of them are mandatory for calculating the monthly payment. If all such fields are present correctly that will be sufficient to run payroll and this will meet the first definition of data quality. For doing manpower planning, skill planning, dynamic work allocation and effective utilization of manpower most of the attributes should have the right quality of data and this will meet the second definition of data quality.

1. Have the right mix of People, Process and Technology with adequate support from top management is the first step to improve data quality.
2. Install a system to measure and improve a set of Quality Dimensions like
3. Uniqueness, b. Precision, c. Conformity, d. Consistency, e. Completeness, f. Timeliness, g. Relevance.
4. Data accuracy, Data validity, Data Integrity are the other aspects of good data quality management.
5. There should always a single source for Data and we should avoid getting it from multiple resources.
