databasename

Databasename is the label used to identify a database within a database management system. It is used to distinguish one database from others on the same server or instance and is typically unique within that scope.

In relational systems, the database serves as the top-level container for objects such as tables, views, indexes, procedures, and stored data. A server can host multiple databases, each with its own objects, users, and permissions.

Naming rules vary by system but common guidelines apply: use letters, digits, and underscores; avoid spaces and unusual characters; keep within length limits (for example, PostgreSQL 63 chars, MySQL 64, SQL Server 128). Names may be case-sensitive or insensitive depending on platform and filesystem. Avoid reserved words and consider portability across environments.

Creating, altering, or dropping databasename is performed with administrative commands or tools. Renaming a database is supported in some systems but can require downtime and updates to backups, connection strings, and scripts.

Applications connect to a specific databasename via a connection string or DSN. Queries then operate within that database's scope unless linked or cross-database queries are used.

Security and administration: Access is controlled at the database level with users and roles granted permissions on databasename. Separate credentials help isolate data and enforce least privilege.
