A Glossary of Essential Data Management & Hygiene Terms for HR & Recruiting Professionals
In today’s fast-paced HR and recruiting landscape, data is your most valuable asset. But raw data alone isn’t enough; it needs to be clean, accurate, and strategically managed to drive informed decisions and power efficient automation. This glossary demystifies key data management and hygiene terminology, providing HR and recruiting professionals with the foundational knowledge to optimize their operations, enhance candidate experiences, and ensure compliance in an increasingly data-driven world.
Data Hygiene
Data hygiene refers to the process of cleaning and maintaining data to ensure its accuracy, consistency, and completeness. For HR and recruiting, this means regularly identifying and correcting errors, removing duplicate records, updating outdated information, and standardizing formats within your ATS and CRM. Poor data hygiene can lead to inefficient outreach, skewed analytics, and compliance risks. Implementing automated data cleaning routines through platforms like Make.com can significantly reduce manual effort, ensuring recruiters always work with reliable candidate profiles and contact information, leading to better engagement rates and more effective hiring campaigns.
Data Integrity
Data integrity is the maintenance of data accuracy, consistency, and reliability over its entire lifecycle. In an HR context, this ensures that candidate profiles, employee records, and performance data are complete, correct, and unchanged unless authorized. For instance, if a candidate’s status changes from “Interviewing” to “Hired,” data integrity ensures this update is accurately reflected across all connected systems without corruption or loss. Automation plays a crucial role here by enforcing validation rules during data entry and automatically syncing updates between systems like your ATS, HRIS, and payroll, preventing discrepancies that could lead to administrative headaches or compliance issues.
Single Source of Truth (SSOT)
A Single Source of Truth (SSOT) is a concept where all relevant data elements for a specific piece of information are stored in one primary location, ensuring that everyone in an organization accesses the same, consistent data. For HR and recruiting, this often means designating a specific system (e.g., your ATS for candidate data or HRIS for employee data) as the authoritative source. Instead of disparate spreadsheets or fragmented databases, an SSOT powered by automation ensures that when a candidate’s contact information is updated, all other integrated systems automatically reflect that change, eliminating confusion, reducing errors, and saving valuable time otherwise spent reconciling conflicting information.
Data Governance
Data governance is the overall management of the availability, usability, integrity, and security of data in an enterprise. It establishes the policies, procedures, roles, and responsibilities for managing data assets. For HR, data governance outlines who can access sensitive candidate PII, how long records are retained, and the protocols for data privacy compliance (like GDPR or CCPA). Implementing robust data governance ensures ethical data handling, mitigates security risks, and provides a framework for automation initiatives, guaranteeing that automated workflows adhere to organizational and legal standards, protecting both the company and the individuals whose data is managed.
Applicant Tracking System (ATS)
An Applicant Tracking System (ATS) is a software application that enables the electronic handling of recruitment and hiring needs. An ATS can be used to post job openings, collect applicant resumes and data, screen candidates, and manage the entire hiring process from application to offer. For HR and recruiting professionals, the ATS is often the central hub for candidate data. Automation integrates with the ATS to streamline tasks like resume parsing, initial candidate screening, interview scheduling, and even sending automated rejection or offer letters, significantly enhancing efficiency and improving the candidate experience by ensuring timely communication and clear process navigation.
CRM Data
CRM (Customer Relationship Management) data, in a recruiting context, refers to information collected and managed about potential candidates, past applicants, and talent pool members. This includes contact details, communication history, skill sets, career interests, and past interactions with your organization. For HR, robust CRM data allows for proactive talent pooling, nurturing relationships with passive candidates, and personalizing outreach. Automated CRM systems can segment candidates, trigger personalized follow-up sequences, and track engagement, turning a static database into a dynamic, actionable resource for building strong talent pipelines and accelerating future hiring cycles.
Data Standardization
Data standardization involves transforming data into a common format or set of values, ensuring consistency across various systems and records. For example, standardizing job titles (“Sales Rep” instead of “Sales Representative” or “Account Manager”), date formats, or location entries ensures that search queries yield accurate results and reporting is reliable. In recruiting, this prevents issues where the same candidate might appear under different spellings or job histories are inconsistently logged. Automation tools can apply standardization rules automatically upon data entry or during batch processing, improving data quality and making it easier to analyze trends, build consistent pipelines, and integrate with other HR tech platforms.
Data Deduplication
Data deduplication is the process of identifying and removing redundant copies of data within a database or system. For HR and recruiting, duplicate candidate records are a common pain point, leading to multiple outreach attempts to the same person, skewed metrics, and wasted recruiter time. An effective deduplication strategy ensures that each candidate has only one comprehensive profile, consolidating their application history, communication logs, and notes. Automation can be configured to detect potential duplicates based on criteria like email address or phone number, prompting users to merge records or automatically consolidating them, thereby maintaining a clean and efficient talent database.
Data Validation
Data validation is the process of ensuring that data is accurate, complete, and correct according to specified rules or constraints before it is accepted into a system. For example, a data validation rule might ensure that a candidate’s email address contains an “@” symbol and a domain, or that a salary range field only accepts numerical values within a defined scope. In HR, this prevents the entry of malformed or incorrect data into an ATS or HRIS. Automation tools can enforce these validation rules at the point of entry (e.g., in an online application form) or during integration processes, preventing dirty data from ever entering your core systems and ensuring downstream processes rely on clean inputs.
Data Migration
Data migration is the process of transferring data between computer storage types, formats, or computer systems. This is a critical process for HR and recruiting teams when implementing a new ATS, CRM, or HRIS, or consolidating multiple systems. It involves extracting data from the source, transforming it to fit the new system’s requirements, and loading it into the destination. Without careful planning and execution, data can be lost, corrupted, or incorrectly mapped. Automation scripts are invaluable during data migration to cleanse data, standardize formats, and manage the transfer process efficiently, minimizing downtime and ensuring a smooth transition to new platforms.
Data Retention Policy
A data retention policy defines how long specific types of data should be kept and when they should be securely deleted or archived. For HR and recruiting, this is vital for compliance with privacy regulations (e.g., GDPR, CCPA) which mandate limits on how long candidate and employee data can be stored. This policy dictates, for instance, how long unsuccessful applicant data can be kept before anonymization or deletion. Automation can be configured to enforce these policies by setting up automated triggers to review, archive, or delete records after their retention period expires, reducing legal risk and ensuring responsible data stewardship without constant manual oversight.
Personally Identifiable Information (PII)
Personally Identifiable Information (PII) is any data that can be used to identify a specific individual. In HR and recruiting, this includes names, addresses, phone numbers, email addresses, social security numbers, birth dates, and even employment history or educational background when linked to an individual. Protecting PII is paramount for privacy and legal compliance. Data hygiene practices, robust security measures, and strict access controls are essential. Automation can help by encrypting PII, restricting access based on user roles, and ensuring that PII is only shared with authorized systems and individuals, thereby minimizing the risk of data breaches and maintaining candidate trust.
Workflow Automation
Workflow automation refers to the design and implementation of systems that automatically execute a series of tasks or steps based on predefined rules, without human intervention. In HR and recruiting, this can transform operations by automating tasks such as sending automated interview invitations, onboarding document distribution, background check initiation, or candidate communication based on their status in the hiring pipeline. By linking systems like ATS, CRM, and communication platforms, automation reduces manual effort, speeds up processes, and ensures consistency. This frees up recruiters to focus on high-value activities like candidate engagement and strategic talent sourcing, rather than repetitive administrative tasks.
Data Enrichment
Data enrichment is the process of enhancing existing data with additional, relevant information from internal or external sources. For HR and recruiting, this means adding more context to a candidate’s profile beyond what they initially provided. This could involve automatically pulling publicly available professional data (e.g., LinkedIn profiles, GitHub contributions for tech roles), skills verification data, or demographic insights from third-party tools. Automation can integrate with these external services to automatically enrich candidate profiles in your ATS or CRM, providing recruiters with a more comprehensive understanding of a candidate’s qualifications, experience, and potential fit, leading to more informed and faster hiring decisions.
Candidate Experience Data
Candidate experience data refers to information collected about a candidate’s perceptions and feelings throughout the entire recruitment process, from initial application to onboarding or rejection. This includes feedback from surveys, interview ratings, response times, communication frequency, and even sentiment analysis from interactions. Analyzing this data helps HR and recruiting teams identify pain points, optimize their processes, and improve how candidates perceive the organization. Automation can facilitate the collection of this data (e.g., sending automated post-interview surveys) and help analyze trends, ensuring a positive and engaging candidate journey which is crucial for employer branding and attracting top talent.
