Conclusion
What is data quality and why does it matter?
Good quality data is accurate, clean, and can be used to make actionable business decisions. Raw business data usually has issues like incorrect formatting, duplicate entries, invalid entries, and more. All these issues can skew your data analysis, leading to poor decision-making or inefficient business process workflows.
Because of this, cleaning raw data is an important step toward improving data quality for accurate and efficient data management strategies.
What is data cleaning?
Data cleaning is the process of identifying different data inaccuracies and fixing them, ensuring only good data is used for business analysis or workflow processes. Without clean data, businesses could make strategic decisions based on flawed data, leading to missed opportunities or, worse, financial losses.
Data cleaning: step-by-step
Step 1: Data integration:Source all the necessary data from various places to solve a particular goal. For example, to manage leads better, source data from multiple lead generation forms.
Step 2: Fix data issues:Remove duplicate data, irrelevant data fields, and formatting issues.
Step 3: Enrich data:Fill empty cells by enriching data, either by extracting information from the existing data or by using a reference dataset.
Step 4: Reshape data: Fix structural issues and identify outliers.
Step 5: Build a good data culture:Build consistent data cleaning processes to ensure they can be followed across the organization.
Step 6: Automate: Re-run, recreate, and enhance the existing processes as data grows.
Different ways to clean data
There's more than one method to clean your data; depending on skillsets and time, manual or self-service data cleaning tools can be used.
Manual data cleaning
Manual data cleaning is done mostly through spreadsheets. Tools such as Microsoft Excel and Google Sheets let you manually review, format, and clean raw data to prepare it for analysis. Advanced features like pivot tables, data validation, and conditional formatting assist in basic data analysis and visualization, but they won't scale when it comes to larger datasets. Repeated data cleaning can be time-consuming and may introduce human error.
Automated data cleaning
If you're tech savvy, coding solutions like SQL and Python can be used to automate the data cleaning process. Algorithms can identify data issues and fix them. They can also be used to transform, reformat, and perform other operations to clean and improve data.
These solutions work on larger datasets but require time and effort to scale. It's difficult to scale for anything above 100 million rows. You can employ machine learning techniques to detect patterns and anomalies in large datasets and automatically correct common data issues.
Advanced features of these data cleaning applications include data profiling, which provides insights into dataset structure and content, and data standardization, which ensures consistency across different data sources. While automated solutions can significantly help in data cleaning, you must always review the changes made by these tools to ensure accuracy.
Cloud-based data cleaning solutions
These are web-based data cleaning solutions that can be automated. They help deduplicate data, fix formatting issues, remove inconsistencies, establish data standardization, and organize data profiling.
The biggest advantage of these are the collaboration features, where more than one person can contribute to data cleaning.
Even though they offer convenience, there are limitations in cloud-based solutions. It can be tricky to perform complex data fixes on extra large datasets, and not all cloud-based solutions offer coding options to cater to such needs. Also, you have to pay attention to the security and governance aspect of these tools, as data security should be a top priority.
