Is SQL OLTP or OLAP?

In this article, we learn about Online Transaction Processing System (OLTP) and Online Analytical Processing System (OLAP). OLTP and OLAP both are online processing systems. OLTP is an online database modifying system, whereas OLAP is an online database query answering system. Since the database is created in a normal SQL Server instance, so it's an OLTP database as OLAP databases are created in Analysis Server instances only. Moreover, you cannot insert, update or delete from OLAP databases, so as a software developer you don't have the option to use OLAP as the core database for your solution.

Is SQL an OLAP?

An OLAP cube, also known as multidimensional cube or hypercube, is a data structure in SQL Server Analysis Services (SSAS) that is built, using OLAP databases, to allow near-instantaneous analysis of data. The topology of this system is shown in the following illustration.

Is SQL OLTP?

In-Memory OLTP is the premier technology available in SQL Server and SQL Database for optimizing performance of transaction processing, data ingestion, data load, and transient data scenarios.

Is ETL OLAP or OLTP?

ETL commonly features both OLTP and OLAP databases. Data is extracted from one or more OLTP sources, then transformed and loaded into an OLAP system.

What is OLTP and OLAP in MySQL?

Online transaction processing applications are high throughput and insert or update-intensive in database management. Some examples of OLTP systems include order entry, retail sales, and financial transaction systems. OLAP (Online Analytical Processing)

What is the difference between OLAP and OLTP databases?

What are the key differences between OLAP and OLTP databases. Specifically in terms of implementation (rather than use cases). OLAP is of course primarily used for reporting while OLTP is used for handling transactions. I understand that OLAP databases are optimized for read over write, and that OLAP databases contain more denormalised data.

Why can't I use OLAP as a core database?

Since the database is created in a normal SQL Server instance, so it's an OLTP database as OLAP databases are created in Analysis Server instances only. Moreover, you cannot insert, update or delete from OLAP databases, so as a software developer you don't have the option to use OLAP as the core database for your solution.

Can SQL Server be used as an OLAP engine?

OLAP is a workload, not a specific technology. It's perfectly viable to use standard SQL Server as an OLAP engine. – Thomas Kejser Jan 17 '15 at 12:15 I know it is not related to a specific technology but the question mentioned that SQL Express is used which is an edition of SQL Server.

Is it possible to query OLAP databases with normal SELECT statements?

Not only that, you cannot query OLAP databases with normal SELECT statements, you should use MDX statements. The OLTP stands for Online Transaction Processing, meaning that it depends on transactions.
