# Data

> Data means raw facts, numbers, and records stored in a processable form — the foundation of every application, analytics pipeline, and business decision.

**Data** refers to raw facts, numbers, text, images, or signals recorded in a form that allows storage and processing — today, almost always a digital form. On its own, data carries no meaning; it becomes information only once it is organized and interpreted in context. In computing, data is the fundamental raw material: every application, website, and analytics system ultimately collects, stores, transforms, and serves it.

## How data is classified and managed

Data is commonly grouped by structure: **structured** data lives in tables with a fixed schema, as in a relational [database](https://nodea.io/en/glossary/database); **semi-structured** data such as JSON documents or server logs carries its own flexible markup; and **unstructured** data covers documents, emails, images, and video. Another useful lens is purpose — personal, transactional, telemetry, or behavioral data. Every dataset also moves through a lifecycle: acquisition, validation, storage, processing, archiving, and deletion. Across all stages, three security properties apply: confidentiality (only authorized access), integrity (no undetected tampering), and availability (data reachable when needed) — the classic CIA triad of information security.

## Practical applications

Businesses run on data. Sales analytics, demand forecasting, personalization, and fraud detection are all forms of data processing, ranging from simple reports to [data science](https://nodea.io/en/glossary/data-science) models trained on [big data](https://nodea.io/en/glossary/big-data) volumes. On the infrastructure side, data demands deliberate storage choices — databases, object storage, caches — and disciplined backup routines, because losing production data without a tested restore path is among the most expensive failures an organization can suffer. There is also a legal dimension: personal data processing in the EU falls under the GDPR, which mandates a lawful basis, data minimization, encryption, and access control. Treated well, data compounds into a durable competitive asset; neglected, it turns into operational and regulatory risk.

### What is the difference between data and information?

Data consists of raw, uninterpreted facts — a stream of numbers or events. Information is data that has been organized and interpreted in context so that it carries meaning and can support a decision. The same dataset can yield different information depending on the question asked.
