List of steps in Data Profiling and Data Quality…

Data Profiling:
Data profiling is all about getting to know your dataset better! It involves looking at its structure, content, and the relationships between different pieces of data. By analyzing patterns, distributions, and any inconsistencies, we can understand what the data is telling us.
The main goal of data profiling is to explore and summarize your dataset’s unique characteristics. Think of it as a warm-up before diving into other important tasks like data cleansing or transformation. It sets the stage for making sure your data is in great shape!
Analyzing column statistics (e.g., minimum, maximum, mean).
Identifying data types and formats.
Detecting patterns and anomalies.
Establishing relationships between tables or columns.
Exploratory data analysis (EDA), SQL Scripting, Statistical tools in programming/stat libraries, Informatica, and DataStage profiling tools are tools and techniques. Most ETL tools have features to support Data Profiling and Data Quality operations.
Data profiling is a fantastic way to gain insights into your datasets! 📊 It helps you spot null values, discover patterns, and uncover potential relationships, making it easier for organizations to understand and make the most of their data truly. 💡✨
Data profiling is usually compared with data quality. Let’s examine data quality and the difference.
Data Quality:
Data quality is about how well a dataset meets specific standards like accuracy, completeness, consistency, and relevance. Essentially, it ensures that the data works well for its intended purpose! 📊
The focus is on making data as useful as possible by spotting and fixing problems like errors, missing information, or anything that might be outdated. 🛠️ It’s a continuous effort to keep our data in tip-top shape! ✨
Validating data against business rules.
Cleaning data (e.g., removing duplicates or correcting errors).
Monitoring for ongoing quality issues.
Enforcing data governance policies.
Tools and Techniques are rules-based validation, cleansing algorithms, and exception handling by application programming.
Overall, Data Quality delivers accurate, reliable, and ready datasets for use in decision-making, analytics, or operational processes.
Both are crucial for effective data management:
Data profiling provides the foundation for understanding the dataset, while data quality ensures the dataset meets the standards required for business operations or analytics.
