7 Best Practices for Data Hygiene to Keep Database Clean and Accurate

Define and standardize data fields

Data standardization involves converting data into a standard format and applying the same naming conventions, structures, and validation rules in different datasets and systems. Standardizing data fields is important for maintaining data hygiene as it improves data quality, provides reliable analytics and reports, and increases operational efficiency. It also ensures compliance with regulations like HIPAA and GDPR and helps in smooth integration with CRMs, cloud storage, and APIs. Businesses can standardize their data fields by clearly defining data standards, auditing and profiling data, using standard templates, automating validation, documenting standards, training staff, and continuously monitoring data quality.

The data discovery phase is an important step in this process, which involves the systematic collection, cataloging, and analysis of data from different sources to understand what data exists, its quality, and where it is stored. This phase includes identifying data repositories, such as CRM (Customer Relationship Management) systems, cloud storage platforms, APIs, spreadsheets, and databases.

Businesses then define data entry standards, such as using the ISO format (YYYY-MM-DD) for dates, formatting US phone numbers as (XXX) XXX-XXXX, entering international numbers as +[country code][number], standardizing address abbreviations and casing, using a proper case for names, and assigning unique identifiers to each entity to avoid duplication.

Utilize data segmentation

Data segmentation is the process of dividing a large dataset into smaller and well-defined groups based on specific criteria such as demographics, behaviors, or other relevant attributes. This helps organizations analyze, understand, and target different customer groups more effectively, and helps in customizing marketing, sales, and product strategies.

Clean data is important for better customer segmentation and optimizing GTM (Go-to-Market) strategies. High-quality and accurate data makes sure that segments are meaningful and actionable, which helps in precise targeting and messaging. Businesses identify accurate customer preferences, behaviors, and needs with the help of clean data. It helps them in creating personalized campaigns and accurate resource allocation. Data segmentation, without clean data, can result in wrong insights, wasted resources, and missed opportunities. Jeff Ignacio, the head of Revenue and GTM Operations at Regrow Agriculture, says, “As a Head of Revenue Operations, I’m going to my product team, and I’m saying: I need to have these product signals flash to my go-to-market teams to determine the right go-to-market play. This will drive your GTM motion”.

Enhance data quality

Enhancing data quality is the process of improving the accuracy, completeness, consistency, and reliability of an organization’s database. This involves data enrichment, where existing records are kept with additional information from internal and external sources to provide an overall view of customers and prospects.

Businesses need to balance internal data such as CRM records and customer interactions with external data like firmographic or intent data from third-party providers to generate accurate and comprehensive market insights. This helps businesses fill the gaps, correct outdated information, and get a clear understanding of their target audience.

Third-party data and specialized data hygiene tools help in maintaining up-to-date and accurate contact information. Third-party data providers give verified and current details that help organizations correct errors, remove duplicates, and update old records. Data hygiene tools automate these processes and make sure that databases remain clean and actionable.

There is a direct connection between data quality issues and business risks or opportunities. “When there’s data smoke, there’s business fire”, according to Thomas C. Redman in his book titled “Data Driven: Profiting from Your Most Important Business Asset”.

Implement automation tools

Implementing automation tools means using software solutions to automatically identify and remove duplicate, incomplete, or inaccurate data.

Automation tools are important to improve data integration, accuracy, and hygiene by systematically identifying discrepancies, updating records in real time, and eliminating duplicates. These tools reduce manual errors and make sure that organizations have reliable and actionable data for decision-making. For example, eCommerce companies use AI-based deduplication algorithms to merge duplicate customer records and standardize data formats.

Automation tools use API connectors to automate data between systems to keep information in sync and prevent silos. Real-time synchronization, webhook triggers, and automated import make updates to the CRM, sales, and marketing platforms. Businesses catch and resolve integration issues quickly with error handling, logging, and monitoring.

Automation reduces manual data entry mistakes by using form prefill, data lookup, and validation rules. Automated cleansing systems regularly scan the data to identify issues. Data quality scoring algorithms, workflow-based remedies, and anomaly detection help identify and fix the problems. The deduplication feature in automation tools uses fuzzy matching and weighted scoring to spot duplicate records.

Remove silos

Removing silos means breaking down isolated data storage and access barriers within an organization to create a single and accessible data environment.

Businesses need to promote a strong data hygiene culture and cross-team collaboration. This helps teams identify errors early, standardize data formats, and remove duplication when they work together, and share responsibility for data quality.

Businesses also need to implement advanced data security and compliance measures to protect sensitive information and optimize data. They use strong security protocols, such as access controls, encryption, and regular audits, to protect data from breaches and unauthorized use. They ensure compliance with regulations like GDPR or HIPAA to make sure that data handling meets legal standards.

Audit database

Auditing the database involves systematically reviewing and analyzing a database to check its accuracy, completeness, consistency, and compliance with internal standards and external regulations.

Organizations need to audit their data as it helps them identify quality issues such as errors, duplicates, outdated information, and inconsistencies, which undermine their decision-making power and operational efficiency. They have to consider all types of data, including customer, financial, and employee data. Then they need to select a representative data sample from different categories through techniques like audit sampling. This helps them detect problems within large datasets without auditing all information, which saves their time and resources.

It is important for organizations to check for duplicate records, spelling mistakes, and multiple naming conventions to maintain their business operations. They have to audit their data at regular intervals, update data standards, and adapt to changing data needs.

Assemble a team of data specialists

Assembling a team of data specialists means hiring professionals with expertise in data management, analysis, and governance to check, maintain, and improve the quality, accuracy, and security of an organization’s data.

Data specialists are responsible for collecting, processing, and verifying data from multiple sources. A well-structured data team includes data engineers, analysts, governance specialists, and quality analysts. Each of them focuses on different aspects of data quality, compliance, and security.

Assembling a team of data specialists is important for maintaining strong data hygiene, and ensuring accuracy, consistency, and compliance across all data processes within an organization. This team actively monitors data quality, resolves issues, and ensures compliance with data regulatory standards to keep the data of an organization trustworthy and reliable. Their expertise supports ongoing improvements in data management and also promotes a culture of data responsibility.

What is data hygiene?

Data hygiene is the process of maintaining a database that is accurate, consistent, and free from errors or duplicates. It involves processes such as correcting inaccuracies, removing duplicate records, and standardizing entries to verify that information is clean, up-to-date, and reliable.

Data hygiene is important for organizations because it guarantees that their databases contain trustworthy and actionable information, which is important for generating verified leads and making informed business decisions. Data decay costs businesses millions monthly, and on average data decays at a rate of 30% per year. Maintaining clean and reliable data helps businesses in better marketing and sales outcomes, and also builds customer trust which improves overall operational efficiency.

What is the difference between data quality and data hygiene?

The difference between data quality and data hygiene is explained below.

Data quality

Data quality is a metric that assesses the state of data based on factors such as accuracy, completeness, consistency, reliability, and timeliness.

Data Hygiene

Data hygiene is the practice of maintaining clean, accurate, and organized data within an organization.

The main difference is that data quality is the overall standard of data for accuracy, completeness, and relevance, while data hygiene means the ongoing practices to clean and maintain that data.

What are the steps for better data hygiene?

The steps for better data hygiene are to audit the data regularly, regulate data standards, eliminate duplicates, correct inaccuracies, refresh your data, and train the staff.

The steps for better data hygiene are listed below.

1.  Audit the data regularly: Auditing the data regularly means systematically reviewing and checking the data quality after particular intervals. Regular data audits identify errors, inconsistencies, and outdated information, which helps organizations maintain data integrity by checking issues such as incomplete records, duplicates, and incorrect entries. Companies should use tools like Excel, and Google Sheets, and data hygiene tools like BookYourData to automate the process of audit.
2. Regulate data standards: Regulating the data standards means establishing and following the same rules for data entry and formatting. Setting clear data standards, such as naming conventions, required fields, and formatting rules, verifies all data is entered uniformly. Companies should assign this responsibility to team members to ensure data accuracy and compliance with data regulations, such as GDPR and CCPA. This approach makes it easier for organizations to manage, search, and analyze the data.
3. Eliminate the duplicates: Organizations eliminate the duplicates for better data hygiene by identifying and removing repeated records from their databases. Duplicate records cause confusion and errors, so companies use deduplication tools or manual review to maintain a single and accurate version of each data entry. 
4. Correct the inaccuracies: Correcting the errors means rectifying incorrect or outdated information in your database. Companies should regularly update and validate data to check that all information is current and accurate, which is important for reliable reporting and communication.
5. Refresh your data: Refreshing the data involves updating your database with the most relevant and updated information. Organizations are supposed to periodically refresh data, such as updating contact details or removing obsolete records, to keep their database relevant and useful for business needs.
6. Train the staff: Training the staff means educating the employees about proper data management practices. Companies provide training to ensure that everyone understands data hygiene protocols, which reduces the risk of errors and promotes consistent and high-quality data entry in the organization. Ask the employees to update the records after interacting with the clients and verify data accuracy before entering it into your system.
