12 Open Source Data Profiling Tools for Software Developers

What is Data Profiling?

Data Profiling is the process of reviewing, examining, analyzing, and creating useful summaries of the data. This is an important tool that is used by businesses and organizations to make better data decisions. It is usually carried out by using statistical analysis in which the software draws conclusions about the content and its quality and determines whether the said data meets business standards.

In layman’s terms, data profiling helps us discover, understand and organize our data. And it is important for a business and organization to be able to handle their data. It involves collecting data types, length, and their recurring patterns; performing data quality assessment, discovering metadata and assessing its accuracy, performing inter-table analysis, etc.

Why Data Profiling?

Data profiling provides a lot of information about the quality and utility of a data set which requires very little human effort. It tells about what information is contained in which data set so that you can decide whether or not to retain it. It also talks about the amount of data cleansing effort that will be needed to merge one data set with another data set.

Following are some open source data profiling tools:

1. Aggregate Profiler

This open-source tool performs data profiling and analysis in file formats such as RDBMS, XLS, etc. This tool can also be used for data filtering, quality checks, enrichment; anomaly detection, looking into metadata, similarity checks, etc.

2. IBM Infosphere Information Analyzer

A data profiling tool by IBM helps in recognizing the data quality, content, and structure. It can carry out different profiling actions such as:

Column analysis: Also called the combination of columns is utilized to recognize details in each column of every source table

Primary key analysis: This function is used to recognize the columns that are qualified to be the primary key

Natural key analysis: This key allows you to uniquely identify distinct values in the column such as social security numbers. You can also review the natural key analysis results too.

Foreign key analysis: Foreign keys act as cross-reference keys. They are columns that point out the primary keys of another table.

Cross-domain analysis: The job of this key is to identify columns that have a common value. It does so by examining the content and its relationships across the tables.

3. Informatica Data Profiler

This data profiling tool helps find the data issues even before they become data problems. This is a technique used to analyze the quality, content, and structure of the course data.
