Abstract

This paper is devoted to the idea of using interval data in relational databases. We show, on several simple examples, that interval data can be added to the query language SQL and used with a great effect in business applications of relational databases.

Since the examples are simple, they do not require any new mathematical results or non-trivial algorithms, only standard formulas of interval arithmetic.

The intended audience includes both interval researchers and specialists in relational databases. For researchers who are not well familiar with interval computations, we have included the detailed description of interval arithmetic (that can be skipped by other readers).

Abstract

В работе рассматривается возможностъ исполъзования интервалъных даннын с реляпионными базами аанных. На несколъких простын примерах показано, как интервалъный тип вволится в яапросов SQL и какую полъзу может принести исполъзование интервалов в деловых применениях реляционных баз данных.

Простые примеры, приводимые в статъе, не потребовали никаких новых математических средств или нетривиалъных алторитмов. ИсполъзовалнсЩ толъко станлартные формулы интервалъной арифметики.

Работа может бытъ интересна как иссяелователям, занимаюпимся интервалъной математикой, так и спепиалистам по реляпионным базам ланных. Для тех, кто слабо знаком с интервалъными вычислениями, приводится подробное ввеление в интервалъную арифметику, которое более полготовленные читатели модут пропуститъ.
