Classification in data management
From the data management perspective, classification of data is the process of tagging data to make it more searchable and trackable for entities in charge. This involves categorizing data into relevant classes based on characteristics like format, source, content, and intended audience, as part of a broader process of data discovery and classification. To achieve that, data is accurately tagged and, as a next step, organized into distinct categories or classes.
Establishing a strong data classification policy is crucial in this process, as it provides clear guidelines for how data should be categorized and handled, ensuring consistency and compliance across the organization. This allows organizations to effectively manage and govern information throughout the data lifecycle.
The data lifecycle: Managing data across all phases
The data lifecycle is a crucial framework in data management that outlines the various stages through which data passes, from collection to deletion. Each phase in this lifecycle requires careful attention to ensure data is handled correctly, securely, and in compliance with regulatory standards
With the proliferation of mobile devices, the data generated on these platforms has become a significant part of the enterprise data ecosystem. Mobile data classification plays a key role in this lifecycle, ensuring that mobile-generated data is properly categorized and managed at every stage—from initial collection through to secure deletion.
- Collection and pre-processing. Data is generated or gathered from various sources and prepared for storage.
- Storage. Data is stored in databases or other systems, requiring classification for efficient retrieval.
- Processing. Data is analyzed and utilized for business processes, where proper classification aids in informed decision-making.
- Sharing and usage. Data is shared internally or externally, necessitating clear classification to maintain security and compliance.
- Deletion and archiving. Data is either archived for long-term storage or deleted when no longer needed, with classification helping determine retention policies.
Assessing data classification levels
To ensure that data classification methods are effective, organizations must regularly assess their classification data to ensure:
- Accuracy. How well does the classification reflect the actual data characteristics?
- Consistency. Are classification practices uniformly applied across the organization?
- Compliance. Does the classification meet regulatory requirements and data classification standards?
- Effectiveness. Is the classification helping achieve the intended business objectives?
Assessing these levels not only highlights areas for improvement but also helps organizations adapt their data classification strategies to evolving needs and challenges.
Classification in machine learning
Classification in data mining and ML is a supervised learning technique that involves categorizing data into predefined classes or labels based on the characteristics and patterns identified in the dataset, enabling the prediction of class labels for new, unseen data.
For example, the data classification practice is essential to develop a spam filter for an online inbox. In this case, we refer to building a data classification model, training it, and evaluating its efficiency on test data. When deployed in production, this model can perform predictions on new unseen data.
The goal of data classification in machine learning
In the context of data management and machine learning, data classification serves several crucial purposes:
- Enhances understanding
By categorizing data, organizations gain insight into the value of the information they possess, enabling them to prioritize resources and efforts effectively.
- Facilitates informed decision-making
By properly classifying data, organizations can unlock their full potential for analysis and decision-making, enabling them to derive valuable insights and drive business growth.
The benefits of data classification in data management
- Ensures regulatory compliance
In data management, data classification enables organizations to assess whether their information meets regulatory requirements, helping them identify areas where adjustments may be needed.
How data classification works in practice
While categorization had been a common practice for mankind far before Charles Babbage and the ENIAC, till now the understanding of data classification and the variety of its options, processes, and types have experienced several changes, becoming more diverse and flexible. Let's figure out how to do data classification.
Types of data classification systems
Depending on the ways to manage and organize information and the level of technology enablement achieved, data categorization systems are divided into manual, automated, and hybrid.
Data classification system type
Characteristics
Manual
Rely on human intervention to assign classifications based on the user's judgment or organizational policies.
Example: A user manually marking a document as confidential.
Automated
Utilize software tools, algorithms, or machine learning to automatically assign classifications based on predefined rules or patterns.
Example: Using machine learning algorithms to scan emails and classify them as spam or not.
Hybrid
Combine both manual and automated elements for classification.
Example: Allowing users to manually classify data while using automated tools to assist in the process, ensuring consistency and efficiency.
In practice, data classification examples can illustrate how organizations implement these systems to meet their specific needs, such as categorizing customer data for personalized marketing or classifying financial records to ensure compliance with regulatory standards.
When is the right time to approach data classification?
Over the past years, controlling and managing online data has become the number one objective for global authorities, businesses, individuals, and any other party involved in digital.

At some point, these growing volumes of data require businesses to implement data classification to efficiently handle large datasets, enabling streamlined analysis, actionable insights, and informed decision-making.
- The nature of data changes
With the variety and difficulty of business tasks growing, companies are more likely to adopt AI and ML. The need to solve these tasks and the subsequent technology adoption naturally make data more complex and dynamic. Additionally, the integration of diverse sources of information, including sensor data from IoT devices, social media streams, and real-time customer interactions, contributes to the shifting nature of data and requires organizations to adapt their strategies to get more value and remain operational.
- Data privacy becomes an emerging concern
With a heightened focus on data privacy, businesses acknowledge the imperative to protect sensitive information. Data classification serves as a strategic response to this concern, empowering organizations to identify, label, and safeguard private data, fostering trust among customers, and complying with evolving privacy regulations.
- Cybersecurity concerns start hindering business success
Data makes businesses vulnerable to diverse cybersecurity threats—phishing, ransomware, DDoS, and insider risks. Insecure IoT devices and supply chain vulnerabilities also pose significant risks, addressing which requires proactive measures. By systematically categorizing and prioritizing data based on sensitivity, businesses can implement targeted security measures that safeguard the integrity, confidentiality, and availability of digital assets.
- Regulatory landscape evolves
As the importance of safeguarding online information grows, a surge in regulations emerges to protect individuals and organizations. GDPR (General Data Protection Regulation), PCI DSS (Payment Card Industry Data Security Standard), and other industry-specific mandates directly relate to data, setting stringent standards for its handling, storage, and protection. Data classification serves as a proactive strategy, enabling organizations to categorize information according to regulatory specifications, thereby ensuring adherence to standards and minimizing legal risks.
- The next strategic move is required
Throughout their evolution, organizations naturally engage in transformative endeavors such as mergers and acquisitions (M&A), robust digital transformation, innovation adoption, and global expansion. In these strategic moves, data classification empowers businesses to effectively categorize and protect critical information, ensuring seamless integration of diverse datasets, compliance with regulations, and informed decision-making.
Common data classification challenges
While data classification is a commonly used practice that has shaped our digital experiences and made online shopping, correspondence, and other day-to-day operations possible, it is still characterized by a variety of process-specific imperfections and challenges organizations face in practice.
Manual practices hindering accuracy and efficiency
Although adopting technology to automate data processing is an ongoing promise for 90% of global companies, in reality, 48% of organizations are still taking early steps toward intelligent automation. This means that so far every second company in the world continues to go for manual processes.
Apart from hindering the overall data accuracy and lowering operational efficiency, manual practices became a barrier to compliance success for at least 16% of organizations. This has a very distinct impact on business outcomes.
- Manual handling increases the risk of sensitive data getting lost in data silos, rendering it undiscoverable and unprotected.
- Mishandling sensitive information not only leads to potential embarrassment for clients but also results in the loss of future revenue opportunities.
- Organizations face fines and penalties for the mishandling of regulated data, impacting their financial health.
- Breaches in client information can give rise to lawsuits, ruining the organization's good reputation.
Siloed organizational structures and lack of data culture
For the past decade, the level of data-related responsibility among executives has encountered a myriad of changes triggered by emerging security risks, technology's rapid evolution, and global political changes that have a dramatic impact on business.
At the same time, only a couple of years ago, the share of organizations investing in building in-house data strategies was 13%. For the situation to change for the better, the main shift should be the one in leaders’ minds, as so far the global data culture adoption landscape still looks as follows.
- Leadership often adopts a "it won't happen to us" mindset, potentially underestimating the importance of proactive data management.
- Data and privacy concerns take a back seat to other pressing priorities like sales, marketing, expansion, and product expenses.
- Companies struggle to effectively locate or identify their data.
- Organizations find themselves out of sync with existing compliance regulations.
- Companies are putting too much effort into overcoming data classification process complexities, which makes them disconnected from getting practical results.

Underestimation of data privacy concerns
As we mentioned before, in some sense, data equals privacy. And while consistently leveraging data classification practices allows companies to respect users’ privacy, on the other hand, it also becomes a cornerstone for successful data strategy adoption.
The truth is that for many organizations data classification policies are often theoretical rather than operational, meaning while they exist on paper and in reality bring no measurable impact. This is proved by the fact that according to the Data and Analytics Leadership Executive Survey, only 24% of companies can state they are doing enough to ensure responsible and ethical use of data in 2023.
So, what are the privacy concerns organizations still overlook?
- Data privacy remains topical for specific organizational levels and never becomes a company-wide concern.
- Understanding who is responsible for data ethics and making sure they have the necessary assets to implement and maintain the required level of privacy.
- Controlling how confidential information is shared with other entities.
- Establishing an actionable plan B to apply in case privacy gets compromised.
