Top 10 Data Profiling Tools That Helps Ensure Data Quality

We are no longer impressed by gigabytes and terabytes. With a large amount of increased data around us, the tech industry is coming up with new words to describe data in new formats and sizes. It is impossible to measure and utilize the amount of data we generate every day.

Data must be cleaned, normalized, structured, and analyzed to use for decision-making. Data is available in many formats and not useful unless it becomes information. Data itself turned into a huge ecosystem of products, services, jobs, and talent. Big data and advanced analytics have helped businesses offer personalized, real-time services to their customers. A lot of tools are available in the market that helps data scientists collect, profile, clean, analyze, and visualize data.

In our previous article, we talked about the top 15 data mining tools. Here, we are covering the top 10 data profiling tools that are widely used to profile data. Data passes through various stages before it becomes information. Before we see popular tools for data profiling, let’s first see what data profiling is.

What Is Data Profiling?

Data profiling is the process of reviewing source data and creating informative summaries about that data. Data profiling is combined with the ETL process and is a part of data warehousing and data quality projects.

It involves:

  • Gathering data types, patterns, uniqueness, variation, frequency, and length
  • Collecting statistics and descriptive information
  • Checking metadata and its accuracy
  • Tagging data with keywords, categories, and labels
  • Identifying dependencies, relationships, and structures
  • Fine-tune ETL process and data conversion and migration
  • Performing data quality assessment
  • Assessing risk involved in data integration
  • Understanding data challenges early to avoid problems
  • Determining the accuracy, completeness, and validity of data

Data profiling generally refers to clarifying the structure, content, relationship, and derivation rules of the data. It helps better understand data, improve data quality, shorten the implementation cycle of projects, and discover business knowledge embedded in data itself.

It is an essential part of data management and can be done with various tools, techniques, and analyses. Here are the top data profiling tools that are widely used by developers and data professionals.
