lekérdez

Lekérdez is a Hungarian term used in information technology to denote the act of requesting or retrieving data from a data source. It is commonly employed in contexts such as relational databases, search engines, and web APIs, where a user or program asks for specific data according to defined criteria. In general, a lekérdez is a statement or request that aims to obtain data.

Linguistically, lekérdez is a form of the verb lekérdezni, which means to query or to fetch data. The infinitive is lekérdezni, and the third-person singular present form is lekérdez. The prefix le- often indicates retrieval or extraction. The noun form of the action is lekérdezés (the act of querying), and related terms include adatlekérdezés (data query) and lekérdező (one who queries or a querying tool).

In practice, lekérdezés can refer to a range of operations. In relational databases, SQL queries such as SELECT statements perform lekérdezések to return rows that match conditions. In APIs, lekérdezések may be carried out via query parameters, endpoints, or specialized query languages like SQL, SPARQL, or GraphQL. Effective lekérdezések depend on proper data modeling, appropriate indexing, and query optimization to ensure fast and correct results.
