Organizations are collecting a colossal amount of Structured and Unstructured Data but are struggling to enhance the quality of information for better decision-making. One of the primary reasons companies fail to obtain quality data is the lack of automation. Often companies rely on manually writing code to perform validation, cleaning, and filtering of data. While dated practices can help businesses deal with less data, working with Big Data requires automation for improving data quality.

To expedite the process of Data Cleansing, Data Integration, Data Exploration, etc., companies are leveraging Open-Source Data Profiling Tools. Over the years, Data Profiling has proved to be one of the crucial requirements before consuming datasets for any project. This method is vital for Data Conversion and Migration, Data Warehousing, and Business Intelligence projects.

In this article, you will get an understanding of what Data Profiling is, along with a list of the best Open-Source Data Profiling tools for 2021.

Data Profiling can be defined as the process of examining and analyzing data to create valuable summaries of it. The process helps yield maximum quality from the gathered data and insights within a given dataset, which organizations can use to make effective business growth decisions. As data grows exponentially, keeping up the data quality complexities becomes strenuous for companies for maintaining productivity and efficiency with their data analytics initiatives. 

According to Gartner’s research, the average financial impact of poor data quality on organizations is USD 9.7 million per year. As a result, Data Profiling is an essential process for organizations to garner data that can be instrumental in their analytics workflows. There are now a wide variety of Open-Source and Paid Data Profiling Tools available that can help businesses manage their data better.

Understanding the Types of Data Profiling

Data Profiling encompasses a vast array of methodologies to examine various datasets as well as produce relevant metadata. It also has the capability to protect organizations from costly errors that reside in a database without anyone’s notice.

Some of the crucial types of Data Profiling are as follows:

  • Structure Discovery or Structure Analysis: The Structure Discovery or Structure Analysis examines the complete rows and columns of data to determine whether a specific data is consistent in nature or not. Some of the typical structure discovery techniques include pattern matching, validation with metadata, among others.
  • Content Discovery: Focusing mainly on the quality of data, Content Discovery takes a closer look at the data and helps users in detecting the issues in specific rows and columns of datasets. Content Discovery Data Profiling works by leveraging techniques like outlier detection, uniformity, frequency counts, etc.
  • Relationship Discovery: Relationship Discovery is used to detect the interaction between one data source to another. Relationship Discovery Data Profiling is used to establish links within the data in disparate applications as well as databases.

Understanding the Need for Data Profiling Tools

There are several benefits of Data Profiling tools, some of which are mentioned below:

  • Users can improve the quality of data using Data Profiling Tools.
  • Businesses can identify factors that are having a significant impact on quality issues using Data Profiling Tools.
  • Data Profiling Tools can determine patterns and data relationships for better data consolidation.
  • Data Profiling Tools provide a clear picture of data structure, content, and rules.
  • Data Profiling Tools can improve users’ understanding of the gathered data.
