Difference Between OLAP and OLTP

Difference Between OLAP and OLTP: OLTP along with OLAP both are Online Processing Systems. OLTP is a processing system for transactions and OLAP functions as an analytic processing. 

OLTP is an application that handles transactions-based applications that are available on the internet, like, ATM. 

OLAP is an on-line application that provides reports to multidimensional analytical queries such as forecasting, financial reports and forecasting, among others.


OLAP is an acronym in the term online Analytical Processing. It’s used to analyze of information from databases from multiple databases simultaneously including sales analysis and forecasting market research, budgeting, and more. Data Warehouse is the example of an OLAP system.

OLTP is an acronym for OnLine Transactional Processing. It’s used to maintain the online transaction as well as record integrity across multiple access environments. OLTP is one of the systems that can handle a many small online transactions, for instance, ATM

What is OLTP?

An OLTP system records and stores transactions in databases. Every transaction is a separate database records comprised of columns or multiple fields. Examples include credit and banking card transactions or scanning at retail checkouts.

In OLTP the focus is on processing speed, due to the fact that OLTP databases are written, read and frequently updated. If the transaction fails, built-in technology ensures the integrity of data.

What is OLAP?

OLAP uses complex queries to huge amounts of historical data collected from OLTP databases as well as other sources, to support analysis, data mining or business intelligence-related projects. In OLAP the focus is on speed of response to these complicated queries.

Each query consists of several columns gathered from a variety of rows. Examples include financial performance year-over-year or trends in marketing lead generation.

OLAP database and warehouses of data provide analysts and decision makers the capability to make use of custom-designed reporting tools to convert data into data. Failure of queries in OLAP does not disrupt or delay processing of transactions for clients, however it could affect or delay the accuracy of business intelligence data.

Key difference in OLAP and OLTP

  1. Online Analytical Processing (OLAP) is a type of software tools that analyse the data in databases while Online Transact Processing (OLTP) allows transaction-oriented software with a three-tier design.
  2. OLAP is a platform that can be used that can be used for any type of business analysis needs , including forecasting, budgeting, planning and analysis. OLTP can be used to manage daily transactions of an organisation.
  3. OLAP is defined by a high volume of data. OLTP is distinguished by the large amounts of online transactions that are short.
  4. In OLAP data warehouse, the database is unique in it is able to integrate various sources of data to build an integrated database, whereas OLTP utilizes the traditional DBMS.
