It refers to the systematic collection, organization, storage, retrieval, analysis, and presentation of data using computer systems and software. The practice emerged in the mid‑20th century as electronic computers became widespread, evolving from simple recording tasks to complex analytics, machine learning, and real‑time decision support.

The core processes in tietojenkäsityö include data acquisition, cleaning, transformation, integration, and visualization. Modern systems rely on relational databases, NoSQL stores, data warehouses, and cloud platforms to manage volume, variety, and velocity of information. Techniques such as ETL (extract, transform, load), data mining, and statistical modeling enable insights that drive business strategy, scientific research, public policy, and operational efficiency.

Compliance in tietojenkäsityö requires data governance, risk assessment, and robust security measures.

Tietojenkäsityö is central to many modern professions, including data science, business intelligence, software engineering, and information technology. Continued advances in artificial intelligence, distributed computing, and edge processing promise to expand its scope, demanding ongoing education and ethical consideration.
