PageID

PageID is a term used in computing to denote a unique identifier assigned to a page within a software system. It serves as a reference point that allows the system to retrieve, display, and manage the page’s content, metadata, and permissions. The concept is common across content management systems, wikis, web applications, and database-backed page stores.

Formats and scope vary by platform. A PageID may be a simple integer, a globally unique identifier (UUID), or an alphanumeric token. In many systems, the PageID corresponds to the internal primary key of a record in a pages table, while in others it may appear in URLs as a query parameter or be embedded in routing rules. Page identifiers typically apply to various kinds of pages, including articles, help pages, documentation, or knowledge base entries.

Storage and retrieval methods depend on implementation. PageIDs are usually stored as a dedicated field within a page object or database row and indexed for fast lookup. When a request specifies a PageID, the system uses it to fetch the associated page, its content, and related data such as metadata or access controls. Some platforms also maintain mappings between PageIDs and user-friendly slugs or paths for navigation.

Lifecycle and semantics vary as well. IDs are intended to be stable references, though policies differ on persistence after deletion, id reassignment, or page renaming. Systems may implement soft deletes, redirections, or slug-based aliases to preserve access while maintaining data integrity.
