Paginointia

Paginointia, commonly called pagination in English, is the technique of dividing a large set of items into discrete pages to facilitate navigation and manage data display. It is widely used in web applications, APIs, and document viewers.

There are two main approaches: offset-based pagination and cursor-based pagination. Offset-based pagination uses a page size and an offset value to skip items (for example, LIMIT n OFFSET m in SQL). It is simple but can become slow on large datasets. Cursor-based pagination tracks a stable last-seen key and fetches the next set with a condition such as id > last_id, offering better performance and consistency when the underlying data changes.

In user interfaces, patterns include numbered page links, next/previous controls, or infinite scrolling. Accessibility requires keyboard operability, clear focus indicators, and semantic markup; provide meaningful labels and ARIA attributes for screen readers.

Backend considerations include indexing the order column, choosing an appropriate page size, and handling updates that occur during navigation. API designs may expose metadata such as total results, total pages, and links to first, last, and next pages, or use a token-based continuation method.

Paginointia addresses performance, scalability, and user experience in content-heavy sites, search results, and databases. It is a common practice in web development, with ongoing considerations regarding the trade-offs between offset-based and cursor-based methods depending on data size and update frequency.
