Best Data Profiling Tools For 2024 + A Guide On Selecting The Right One
In a world that’s more connected than ever, data volumes within the enterprise and individual systems continue to rise, data profiling is as important as ever. While managing such a massive amount of data is tricky, there’s another big challenge: data quality management.
Source: Data Ladder
Do you know data quality issues cost companies in the US more than $3 trillion annually? It translates into financial loss, revision in policies, and marred reputation for many businesses.
But why do data quality issues occur?
Because big data is often riddled with errors, lacks consistency, or contains duplicates. This can cause interruptions and complications in business processes, resulting in wasted opportunities and decreased ROI.
This is where data profiling tools come in handy. It analyzes and gives a complete breakdown of the source data to help users understand and uncover actionable insights to improve business intelligence and ensure data is consistent. Data profiling in ETL is vital to ensuring data quality and data integrity.
In this article, we’ll explain what data profiling is, why are data profiling tools essential for businesses, and how data profiling tools help simplify this task.
What is Data Profiling?
Data profiling is the process that helps evaluate data integrity by presenting a complete breakdown of its statistical characteristics, such as error count, warning count, duplicate percentage, and minimum and maximum value, enabling detailed data inspection. This provides a detailed data quality assessment.
Data profiling offers critical insights into the information that an organization can leverage to its benefit for decision-making and analysis.
Data profiling software use analytical algorithms to help scrutinize the data to determine its validity. These tools play a vital role in helping businesses streamline their data strategy with its principles and objectives. Now that we know what data profiling is let’s discuss the different processes that require data profiling.
How a Data Profiling Tool Can Help?
Data profiling tools ensure the validity of data processes as they help you answer the following questions regarding your data:
- Does the data contain any null or blank values?
- Are there any anomalies in the data? Do they have a distinct pattern?
- Does it contain any duplicate values? What is the ratio of unique values?
- What is the range of importance in the source data? Are the minimum and maximum values within your expected range?
Getting the answer to these questions can help you maintain your enterprise data quality and eradicate errors that can negatively influence the business processes.
Data Profiling Tools Use Cases
Generally, data profiling is used in the following processes:
Data Migration
Data migration involves moving a high volume of information across heterogeneous systems, such as files, databases, etc. However, before initiating the transfer via a data migration tool, it is essential to profile the data to identify discrepancies and resolve them to maintain consistency between the old and new systems.
Data profiling tools at an initial stage of migration can reduce the risk of errors, duplications, and incorrect information.
Data Integration
Data integration creates a holistic view of enterprise data by merging it from disparate sources. Profiling data in the initial phase of integration ensures no errors when source data is integrated and loaded into a data warehouse, data hub, or data mart.
Data Cleansing
Data cleaning, a primary step in the data preparation process, helps with error rectification and deduplication to authenticate the validity and relevance of the data. However, data cleansing is only beneficial for data sets you know are corrupt. Often, poor quality data loiters in the system unnoticed and unaddressed until it is identified via data profiling.
Thus, data quality and profiling tools methodically examine vast amounts of data to identify incorrect fields, null values, and other statistical irregularities that might affect data processes.
How to Select the Right Data Profiling Tool
This section will help you decide on the right data profiling software for your business.
Data Sources and Compatibility: Before anything else, the solution you choose should offer connectivity to your required data sources. Many profiling solutions offer pre-built connectors with the option of creating a custom one, as well. See where data is coming from into your company and choose accordingly.
Data Profiling Features: The more the better. Some common features that should be present in your chosen tool are summary statistics, data discovery, data quality assessment, and data distribution analysis. The market leading tools go beyond and offer robust supplementary functionalities, including data validation rules and data visualizations.
Ease of Use: No-code tools are becoming increasingly popular. They empower business users to perform complicated data management tasks, from profiling to data warehouse modeling. Companies can also opt for open-source alternatives. However, these require coding and come with a steep learning curve.
ETL Support: Once data is collected and profiled, it needs to be cleansed, prepared, and loaded into a central location in a structured manner. Robust tools, like Centerprise, allow teams to ETL their data and create end-to-end data pipelines, offering a complete data management solution.
Data Processing Needs and Scalability: How much data needs to be processed? The amount of data ingested varies with the size of the business and will influence the tool teams choose. The volume of data generated and collected by companies might increase in the future, necessitating a scalable software.
Automation and Scheduling: These two features help further streamline workflows and improve efficiency. Automating profiling tasks helps teams focus more on analyzing data and fixing errors in real-time than on data preparation.
Support and Reviews: Teams should look for a vendor that provides thorough trainings based on tailored use cases. Also, they should look for companies that have high support ratings and industry recognition. For reviews, check authoritative sites such as TrustRadius and G2.
