identifikatorlar

Identifikatorlar are names or codes used to refer to entities within a system, enabling storage, retrieval, and manipulation of data. They cover a broad range of objects, including program elements, database objects, and network or user identifiers. In software, identifikatorlar are the identifiers assigned to variables, functions, classes, modules, and other constructs so that a program can reference them consistently during compilation or execution. In data management, identifikatorlar include keys that uniquely identify records, such as primary keys in relational databases or surrogate keys like UUIDs.

In programming languages, identifikatorlar must follow specific lexical rules. They typically must begin with a letter or underscore, may include letters, digits, and underscores, and are often case sensitive. They cannot collide with reserved keywords of the language. Naming conventions vary by language and project, with common styles such as camelCase, PascalCase, or snake_case used to improve readability and consistency.

In databases, identifikatorlar label entities such as tables, columns, indexes, and constraints. Primary keys provide unique identification for records, while foreign keys establish relationships between tables. Designers may choose natural keys, which use real-world attributes, or surrogate keys, such as integer sequences or UUIDs, to ensure stability and performance.

In broader contexts, identifikatorlar include user names, resource identifiers (URIs), and other globally or locally unique values used to enforce identity, access control, and interoperability. Good practices emphasize clarity, consistency, and stability of identifiers to minimize maintenance and integration issues.
