Online Analytical Processing, a category of software tools which provide analysis of data for business decisions. OLAP systems allow users to analyze database information from multiple database systems at one time. The primary objective is data analysis and not data processing. What is OLTP? Online transaction processing shortly known as OLTP supports transaction-oriented applications in a 3-tier architecture. OLTP administers day to day transaction of an organization. Uses of OLAP are as follows A company might compare their mobile phone sales in September with sales in October, then compare those results with another location which may be stored in a sperate database.

OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives. OLAP consists of three basic analytical operations: consolidation roll-up , drill-down, and slicing and dicing. For example, all sales offices are rolled up to the sales department or sales division to anticipate sales trends. By contrast, the drill-down is a technique that allows users to navigate through the details. For instance, users can view the sales by individual products that make up a region's sales. Slicing and dicing is a feature whereby users can take out slicing a specific set of data of the OLAP cube and view dicing the slices from different viewpoints. These viewpoints are sometimes called dimensions such as looking at the same sales by salesperson, or by date, or by customer, or by product, or by region, etc.

Online transaction processing OLTP captures, stores, and processes data from transactions in real time. An OLTP system captures and maintains transaction data in a database. Each transaction involves individual database records made up of multiple fields or columns. Examples include banking and credit card activity or retail checkout scanning. If a transaction fails, built-in system logic ensures data integrity. OLAP applies complex queries to large amounts of historical data, aggregated from OLTP databases and other sources, for data mining, analytics, and business intelligence projects.

Difference Between OLTP and OLAP

The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second. In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model usually 3NF. Queries are often very complex and involve aggregations.

This might include, order creation, logging service request, user creation, lead creation, opportunity creation, recording interactions with end users etc. These systems not only are the tools to record data into system, they are also highly effective in retrieval of small chunk of data. This drives all the necessary technical features of OLTP. Like comparatively low database size, highly normalized database design, lack of historical data, absence of indexes on tables etc.

Сьюзан попыталась осознать то, что ей сообщил коммандер. Она сомневалась, что Танкадо мог передать ключ какому-то человеку, который не приходился ему близким другом, и вспомнила, что в Штатах у него практически не было друзей. - Северная Дакота, - вслух произнесла она, пытаясь своим умом криптографа проникнуть в скрытый смысл этого имени.  - Что говорится в его посланиях на имя Танкадо. - Понятия не имею.


Это было непостижимо. Если информация верна, выходит, Танкадо и его партнер - это одно и то же лицо. Мысли ее смешались. Хоть бы замолчала эта омерзительная сирена. Почему Стратмор отмел такую возможность. Хейл извивался на полу, стараясь увидеть, чем занята Сьюзан. - Что .

 Это где-то здесь, - пробормотала она, вглядываясь в текст.

Он подумал о Сьюзан. Но тут же в голову пришли слова Стратмора: Найдите кольцо. Беккер в отчаянии плюхнулся на скамейку и задумался о том, что делать. Что же предпринять.

 Каким временем мы располагаем. - У нас есть около часа, - сказал Джабба.  - Достаточно, чтобы созвать пресс-конференцию и все выложить. - Каковы ваши рекомендации? - требовательно спросил Фонтейн.  - Что вы предлагаете.

ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Коммандер опустил голову. Его мечте не суждено сбыться. ГЛАВА 104 Сьюзан вышла из комнаты. ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Как во сне она направилась к главному выходу из шифровалки.
