Data Scrubbing

Data Scrubbing, also referred to as Data Cleansing, is the act of correcting your data in a Database that has errors, is incomplete, not properly formatted, or has duplicate entries to make it usable before exporting it to another system. Data Scrubbing is an integral part of Data Science as it would be difficult working with impure data because this will lead to many challenges. A Database Scrubbing Tool generally includes programs that will help in amending specific types of mistakes. Data Scrubbing is done using algorithms, rules, using look-up tables, and other methods

Why Data Scrubbing is Important?

Data Scrubbing is important as there are numerous benefits. For you, as a data professional, having bad quality data would hinder your output and ultimately make you come up with a flawed Analysis which in turn would affect your client’s or employer’s power to make the right decisions about future occurrences. Listed below are some benefits of cleaning up data:

Having clean data, free from errors helps increase your efficiency and allows you to have an optimal analysis which will improve your decision-making process. 
Having incorrect data would mean not having an accurate outcome. Even though your algorithm may be wonderful, it will be processing a wrong Dataset thereby causing you to waste time, effort, and resources as you will be required to carry out the Analysis all over again.
With Data Scrubbing, you can monitor errors as you will be able to see where the errors are coming from making it easy to fix wrong or corrupt data.
Data Scrubbing removes errors like duplicates that are inevitable when multiple sources of data are brought together in a Dataset hence streamlining your data to match what is required for usage.
When you clean up data before trying to get more information from them, your final deductions will be near accurate because they will be fewer errors and this will lead to happy clients, colleagues, employees/employers, management, etc.
With your data scrubbed, It gives you the ability to map its different functions and get clear insights into what the data is intended to do.

Who Should Employ Data Scrubbing?

Data Scrubbing is an essential part of managing data in a well-mannered format. Different industries and sectors require data to be clean to run their daily activities efficiently. But some sectors such as Banking, Finance, Retail, and telecommunication are data-intensive industries that make Data Scrubbing a high-priority stage.

Let’s go through some of the common sources of Database errors listed below:

Human errors during manual data entry.
A lack of company-specific or industry data standards.
Older Systems with obsolete data.
Merging Databases.

Some facts about data quality are listed below:

Due to bad-quality data Ingestion, businesses lose up to 20% of their revenue.
 Managing data quality is time-consuming, and employees waste about half of their working time handling bad-quality data.
In an hour, almost 5 dozen of companies change addresses, and names and 50 new businesses opened, which creates data inconsistency.
Data Scrubbing vs. Data Cleaning vs. Data Cleansing

Many times the question arises what is the difference between Data Scrubbing vs. Data Cleaning vs. Data Cleansing? These terms are used interchangeably when it comes to practically applying them in the data preparation process. 

Data Scrubbing is more related to the number of specialized processes involved in the data preparation such as merging, translating, decoding, and filtering data. Data Cleaning involves the process of cleaning the raw data that involves, filling NULL values, identifying outliers, etc. 

We can use Data Scrubbing, Data Cleaning, and Data Cleansing internally as refer to the same process of data preparation because they have the same end goal. 

How does Customer Data Quality Impacts Business Processes?

Customer data quality is directly proportional to the impact on business decisions, and it ultimately touches every facet of your business.

For example, take the Sales data. The sales team-high relies on quality customer data to deliver the context of the conversations that they have with clients. The low-quality data makes the process cumbersome and harms their ability to speak directly to the customer and address their issue.

Similarly, the Marketing data helps manage the Marketing Campaigns and low-quality data makes it difficult for Marketers and companies to create personalized Campaigns and avoid injecting them into your messaging.

The low-quality data highly impact business operations and lowers the benefits. This unscrubbed customer data grows rapidly and takes up more storage than the cleaned data. It will increase the costs of storage and computation and also slows the process making it harder to search through the data. Businesses miss out on $9.7 million on average due to bad data.

Data Scrubbing tools make all the processes hassle-free as they automate all the Data Scrubbing or data cleaning process by systematically inspecting data based on different rules and algorithms. It makes the data clean and ready for analysis. 

Many Data Scrubbing tools are available in the market but choosing a good one that suits the company’s requirements is still a confusing part. Enterprises use Data Scrubbing tools to automate their data cleansing process and save time.

Data Scrubbing for Effective Data Management Processes

Data Scrubbing plays a vital role in Data Management Processes. Some of the effective processes are listed below:

Data Integration

Data Integration is the process of combining data from multiple data sources into a single unified platform that can store huge volumes of data. The raw data from the data sources is low-quality data that needs to be structured and transformed into a common format. Data Scrubbing cleans the raw data and transforms it into a standard format so that it can be integrated with other data.

Data Migration

Data Migration is the process of transferring data from one system to another. It is essential to maintain Data Integrity and consistency while migrating data from one system to another. It ensures that correct data with the right format and no duplication is replicated to the target system. Data scrubbing tools help clean your data efficiently, ensuring better data quality throughout the enterprise.

Data Scrubbing in ETL Processes

Data Scrubbing plays an important in Data Analytics and decision-making. While the ETL (Extract Load Transform) process takes place Data Scrubbing ensures that only high-quality data passes through and loads into Data Warehouse. High-quality data can be seamlessly used by BI tools, Data Analysts, and Data Scientists for making smarter and better data-driven decisions. Data Scrubbing tools detect anomalies and inconsistencies in data and rectify them automatically. Now cleaned data can be loaded into Data Warehouse or other destinations using an ETL process.

What are the Steps to Perform Data Scrubbing?

You can perform Data Scrubbing, by observing the following:

Removal of Duplicate or Irrelevant Values
Avoid Structural Errors
Convert Data Types
Handle Missing Values
Inform your Team and Co-Workers
1. Removal of Duplicate or Irrelevant Values 

Removing unwanted entries like duplicates and irrelevant data to a given Dataset for further review is a form of Data Scrubbing. Duplicate data easily occurs when you have a collection of Datasets from various sources which will increase the volume of your load while irrelevant data can be described as data that does not fit a specific solution, therefore, it is not needed for that Analysis.

2. Avoid Structural Errors

Structural errors include typos, wrong naming conventions, incorrect capitalization, string size, etc. It is good to fix these errors as they can cause categories and classes to be mislabeled.

3. Convert Data Types 

Another way of Scrubbing Data is to ensure that all data types are uniform across the Dataset. Where a String is applicable, only String values should be inputted as a String cannot be Numeric, neither can a Numeric value be a Boolean and vice versa. In situations where you cannot convert a specific data value, the ‘Not Available (NA) value’ should be used.

4. Handle Missing Values

A lot of algorithms do not accept missing data and there will be missing data in a Dataset and this has to be handled before Analysis can be carried out. Ignoring missing values would be a grave mistake as they can contaminate your data. You can deal with missing value by doing the following: 

Dropping fields that have missing values especially when it is enormous. Doing this might mean losing information so you have to think through and be careful before embarking on this.
You can input the missing values based on observations from the other values like using an average or a range. Having said that, inputting missing values may slightly alter the integrity of the data because you may be operating based on assumptions and not facts.
Thirdly, you can use null values where there are missing values. For example, in cases where Numeric values are needed, 0 can be used to fill up those missing values but you should make sure to ignore these values during Statistical Analysis.
5. Inform Your Team and Co-Workers

After Scrubbing your data, it is important to inform your fellow team, co-workers, etc. of changes done to the data as this would help promote the adoption of the new protocol and create a culture of having quality data within the organization to avoid making similar errors as in the past.

Conclusion

Since most of the work now revolves around data, it is ultimately important more than ever that Databases are as close to perfection as possible. Wrong Data Analysis and submissions can adversely affect a lot of society and this may arise as a result of faulty data.

In this blog post, you learned about Data Scrubbing and how vital it is to always make sure your Database is devoid of mistakes that can greatly affect insights and truncate your efforts and productivity. Procedures on how to clean your data were also touched upon.
