在實(shí)時(shí)數(shù)據(jù)庫(kù)中，我們也需要抽象出基本的數(shù)據(jù)結(jié)構(gòu)來(lái)描述現(xiàn)實(shí)世界的關(guān)系。首先我們分析一下我們要處理的事務(wù)的特點(diǎn)。實(shí)時(shí)數(shù)據(jù)庫(kù)要處理的數(shù)據(jù)都是來(lái)自生產(chǎn)或其相關(guān)數(shù)據(jù)，其主要特點(diǎn)是連續(xù)性和實(shí)時(shí)性。連續(xù)性是指數(shù)據(jù)一直存在，只要生產(chǎn)過(guò)程存在，其數(shù)據(jù)就一直連續(xù)存在，如某化工生產(chǎn)裝置的某檢測(cè)點(diǎn)溫度、壓力、流量等，其數(shù)據(jù)是一個(gè)連續(xù)過(guò)程。實(shí)時(shí)性是指數(shù)據(jù)只有具有時(shí)間戳才具有意義，如說(shuō)某電力檢測(cè)點(diǎn)的電壓是225V，這個(gè)電壓只有和某一個(gè)時(shí)刻對(duì)應(yīng)起來(lái)才有實(shí)際的意義，否則其數(shù)據(jù)將毫無(wú)意義。
根據(jù)上述分析，我們的實(shí)時(shí)數(shù)據(jù)庫(kù)以點(diǎn)做為基本單位來(lái)描述生產(chǎn)數(shù)據(jù)。一個(gè)數(shù)據(jù)庫(kù)的點(diǎn)對(duì)應(yīng)現(xiàn)實(shí)世界的一個(gè)物理點(diǎn)，如某一條生產(chǎn)線(xiàn)的累計(jì)產(chǎn)量、某一個(gè)檢測(cè)點(diǎn)的溫度等。點(diǎn)存貯的數(shù)據(jù)是一段連續(xù)的量，其存貯的數(shù)據(jù)都帶有時(shí)間戳。如對(duì)于一個(gè)溫度點(diǎn)數(shù)據(jù)存貯，我們存貯的是從4月1日到7月1日的數(shù)據(jù)。如果我們檢索出一個(gè)數(shù)據(jù)值為500度，光是500這個(gè)數(shù)值肯定是沒(méi)有什么實(shí)際意義的，同時(shí)我們還要關(guān)心其出于500度所在的時(shí)刻，如2005年5月23日零點(diǎn)。因此，以點(diǎn)做為基本單位來(lái)描述實(shí)時(shí)數(shù)據(jù)，既可以滿(mǎn)足實(shí)時(shí)數(shù)據(jù)的連續(xù)性，又滿(mǎn)足了其實(shí)時(shí)性。
在實(shí)際的應(yīng)用中，如同關(guān)系數(shù)據(jù)庫(kù)一樣，我們也要把各種數(shù)據(jù)管理起來(lái)，因此根據(jù)點(diǎn)和點(diǎn)之間的關(guān)系，我們又把點(diǎn)分成區(qū)域和單元。區(qū)域和單元方便了用戶(hù)管理各種點(diǎn)，如我們可以根據(jù)點(diǎn)所在的位置分成不同的區(qū)域，如在一個(gè)大型化工廠(chǎng)內(nèi)，可以把不同的廠(chǎng)分成不同的區(qū)域，而把廠(chǎng)內(nèi)的不同的車(chē)間分成不同的單元。
同時(shí)，根據(jù)描述對(duì)象的不同，我們把數(shù)據(jù)點(diǎn)分成不同的類(lèi)型，如模擬IO點(diǎn)，數(shù)字IO點(diǎn)等。不同的點(diǎn)類(lèi)型描述了不同數(shù)據(jù)點(diǎn)。
下面將介紹一些數(shù)據(jù)庫(kù)的基本概念：
1）點(diǎn)與點(diǎn)參數(shù)
紫金橋的實(shí)時(shí)數(shù)據(jù)庫(kù)以點(diǎn)為單位來(lái)進(jìn)行數(shù)據(jù)的管理。點(diǎn)是一組有邏輯關(guān)系數(shù)據(jù)值(稱(chēng)為參數(shù)）的集合。在數(shù)據(jù)庫(kù)中，用戶(hù)以點(diǎn)為索引對(duì)數(shù)據(jù)庫(kù)進(jìn)行各種操作，系統(tǒng)也以點(diǎn)為單位管理各種信息。
