Adatkövetelmény

Adatkövetelmény refers to a specification or a set of conditions that data must meet to be considered valid, useful, or acceptable within a particular context. These requirements can originate from various sources, including business needs, technical constraints, regulatory mandates, or quality standards. Understanding and defining adatkövetelmények is a crucial step in data management, data analysis, and system design.

These requirements typically encompass aspects such as data accuracy, completeness, consistency, timeliness, and format. For instance, an adatkövetelmény might state that a customer's email address must be in a valid format, or that all sales transactions must include a product ID and a timestamp. Failing to meet these requirements can lead to errors in analysis, incorrect business decisions, and non-compliance with regulations.

In software development, adatkövetelmények are often documented as part of the system's functional and non-functional requirements. They guide database schema design, data validation rules, and data integration processes. In data science, they inform data cleaning and preprocessing steps, ensuring that the data used for modeling is reliable and appropriate for the task at hand. Effectively managing adatkövetelmények contributes to the overall quality and trustworthiness of data assets.
