lekérések

Lekérések is a Hungarian term that translates to "requests" or "queries" in English. In a computing context, it often refers to database queries, which are instructions used to retrieve specific data from a database. These queries are typically written in a structured query language, with SQL (Structured Query Language) being the most common.

When a user or an application needs information from a database, they formulate a lekérés. This lekérés specifies the data they are looking for, such as particular records, fields, or aggregations. The database management system then processes this query, locates the relevant data, and returns it to the requester.

Beyond databases, the term lekérés can also be used more broadly to describe any type of request for information or action. For example, a user might make a lekérés to a web server for a specific webpage, or a software component might send a lekérés to another component for a particular piece of data. The core concept remains the same: a formal request for something to be provided or done. The efficiency and accuracy of lekérések are crucial for the smooth operation of many digital systems.
