5. Prioritize Data Fields

   
   

   Assign priority to each data field based on its significance and relevance to your business objectives. This step will help you identify which data requires urgent scrubbing.

By following these steps, you can accurately determine what needs to be scrubbed and proceed with the data scrubbing process confidently.

Step 2: Removing Duplicate Data

Duplicate data can cause problems in the accuracy of your database, leading to wasted time and resources. Removing duplicate data is an essential step in the data scrubbing process. Here are some methods for identifying and removing duplicates:

1. Compare Data Fields

Start by sorting all the records in your database and comparing the data fields such as name, email, phone number, and address. Use Excel or Google Sheets to identify duplicates by highlighting the rows with matching data fields.

2. Use Data Matching Software

If you have a large database, using data matching software can save you a lot of time. These tools use algorithms to identify duplicate records and merge them into one clean record. Some popular data matching software includes:

• IBM InfoSphere MDM


• Talend Data Fabric


• SAS Data Quality

3. Leverage Fuzzy Matching

Fuzzy matching is a more advanced method of data matching that takes into account spelling errors, typos, and variations in formatting. This method can help identify records that may not match exactly but are still duplicates. Fuzzy matching is available in many data matching software applications.

By utilizing these methods, you can ensure that your database is clean and accurate, saving time and resources in the long run.

Step 3: Standardizing Data Formats

Once the data has been extracted and cleaned, the next step is to standardize the data formats. Data can come in a variety of formats, which can make it challenging to work with. For example, addresses and phone numbers can be formatted in a variety of ways, which can make it difficult to sort and analyze the data.

Offer Tips and Tools for Standardizing Data Formats

In order to standardize data formats, there are a variety of tools and tips that can help. Here are a few:

• Use Format Templates: One common way to standardize data formats is to use format templates. Format templates are pre-defined formats that can be used to normalize data. For example, format templates can be used to standardize addresses and phone numbers.


• Regular Expressions: Regular expressions are patterns that can be used to match and replace data. Regular expressions can be used to identify and standardize data formats. For example, regular expressions can be used to standardize phone numbers.


• Data Standardization Tools: There are a variety of data standardization tools that can be used to automate the process of standardizing data formats. These tools can be particularly useful for large datasets.

By standardizing data formats, you can ensure that your data is consistent and easy to work with. This can make it easier to analyze and draw insights from your data.

Step 4: Correcting Inaccurate or Incomplete Data

Once you have identified inaccurate or incomplete data in your database, it's important to correct it in order to ensure that your records are up-to-date and accurate. Here are some guidelines for identifying and correcting inaccurate or incomplete data:

• Check for missing information: Review your data fields to ensure that all necessary information is included. For example, make sure that every record has an email address, as this is a vital component in modern communication strategies.


• Verify job titles: Job titles can change quickly, so it's essential to make sure that they are up-to-date. Consider using online tools such as LinkedIn to verify that your records match current job titles and positions.


• Remove duplicate records: Duplicate records can be frustrating and confusing, so it's important to remove them from your database. Use a deduplication tool to identify and merge any duplicate records in your system.


• Correct inaccuracies: When you find inaccuracies, it's important to correct them in your database. For example, if a record has an incorrect phone number or mailing address, update it with the correct information.


• Choose a data scrubbing tool: Consider using a data scrubbing tool to help identify and correct inconsistencies in your data fields. These tools can be incredibly helpful in streamlining the correction process and ensuring that your data is accurate and up-to-date.

By following these guidelines, you can correct any inaccurate or incomplete data in your database, ensuring that your records are reliable and useful for your business needs.

Step 5: Verifying Data

After the data cleaning process, it's important to verify that the data is accurate and up-to-date. Here are some tools and techniques that can be used for verifying data accuracy:

Email Verification Services

Email verification services such as BriteVerify or ZeroBounce can help to ensure that emails in your database are valid and accurate.
