Andmeomadused, or data properties, refer to the characteristics and attributes that describe and define data. These properties help to understand, categorize, and manage information effectively. Key aspects of data properties include data type, which specifies the kind of data (e.g., text, number, date, boolean), and data format, which defines how the data is presented (e.g., date format like YYYY-MM-DD, currency format).

Other important data properties involve data constraints, which are rules that ensure data accuracy and integrity, such as uniqueness, nullability, and range restrictions. Data validity refers to whether the data conforms to predefined rules and standards. Data quality encompasses dimensions like accuracy, completeness, consistency, timeliness, and uniqueness, all of which are critical for reliable data analysis and decision-making.

Metadata, often considered a data property itself, provides information about the data, including its origin, purpose, and how it is structured. Understanding and defining these andmeomadused is fundamental for database design, data warehousing, data integration, and ensuring that data is fit for its intended use. Proper management of data properties facilitates efficient data retrieval, processing, and analysis, ultimately leading to better insights and outcomes.
