adatbázisbejegyzés

An adatbázisbejegyzés, commonly referred to as a database record or entry, is a single, distinct unit of data within a database. It represents a collection of related fields that describe a particular item or entity. For example, in a customer database, an individual adatbázisbejegyzés might contain information about one specific customer, such as their name, address, email, and phone number. Each piece of information within the entry is typically stored in a specific field, and all fields together form the complete record.

Database entries are fundamental to how information is organized and accessed in relational databases. They are often stored in tables, where each row corresponds to an adatbázisbejegyzés and each column represents a field. The structure of these entries is defined by the database schema, which dictates the types of data each field can hold and any constraints that apply. When querying a database, users retrieve specific adatbázisbejegyzés based on certain criteria. The process of adding, modifying, or deleting these entries is managed through database operations like INSERT, UPDATE, and DELETE. The integrity and accuracy of the data within each adatbázisbejegyzés are crucial for the overall reliability of the database.
