Introduction and comparison of OLAP, OLTP

Introduction to OLTP and OLAP Data processing can be broadly divided into two broad categories: online transaction processing OLTP (on-line transaction processing), online analytical processing OLAP (On-line Analytical Processing). OLTP is the main application of the traditional relational database, mainly basic, daily transaction processing, such as bank transac

OLTP data conversion to OLAP data Warehouse

Converting OLTP data to provide acceptable performance in an OLAP system requires the following procedures to be performed: Merging data You must be able to incorporate all relevant information about a specific project (product, customer, employee) from multiple OLTP systems into an OLAP system. The merge process must address the problem of coding differences between different

OLTP and OLAP

The differences between online transaction processing (OLTP) and Online Analytical Processing (OLAP) are mainly distinguished by the following five points. User and system orientation: OLTP is customer-oriented, and OLAP is market-oriented for transaction and query processing. It is used for data analysis. data content: OLTP system manages current data. the OLAP

Transaction log records in in-memory OLTP (Hekaton)

In today's article, I want to discuss in detail how the transaction logs in in-memory OLTP are written to the transaction log. As we all know, in-memory OLTP provides you with 2 persistence (durability) options for your memory-optimized table (Optimized Tables): Schema_only Schema_and_data Today I don't want to talk more about schema_only, because with this option, no logs occur in the tra

Migrate data from OLTP to OLAP

Converts OLTP data to provide acceptable performance in the OLAP system, which requires a series of operations. Merge data First, we must be able to process all relevant information of a specific project (products, customers, employees) from multiple OLTP (on-line transaction processing, online transactions) the system is merged into an OLAP (Online Analytical Processing, Online Analytical Processing

Concepts and optimizations for OLTP (online transactional processing) and OLAP (Online analytical Processing)

OLTP, also called online transaction processing ( Online Transaction Processing ), represents a very high-transactional system, typically a highly available online system, with small transactions and small queries as the primary evaluation of their systems, generally looking at the number of executions per second Transaction Execute SQL . In such a system, a single database tends to process Transaction more than hundreds of, or thousands of, of statem

Sort warnings for in-memory OLTP (Hekaton)

In-memory OLTP is about everything in memory. But that's only half right. In today's article I want to show you that when you read data from memory, even in-memory OLTP can cause disk activity. The problem here is the combination of incorrect statistics and sorting (sort) operators in the execution plan.sorting (sort) operator issuesAs we all know, the sort operator requires a so-called memory Grant to run

Figuring out your business type--OLTP or OLAP

In Oracle database systems, many people are not aware of what their business type is, and are beginning to blindly seek optimization methods, often using OLAP methods in OLTP, or OLTP methods used in OLAP. Such use, sometimes, performance without any improvement, or even greatly affect the performance, get counterproductive effect. So, before you optimize your system, figure out your business type.1. What i

Problems with large transactions in an OLTP environment

In the application environment, often need to ensure the consistency of several tables related data, in order to deal with this demand, development engineers often use transactions, some insert,update and other statements tied together to form a transaction (Transaction), such as the following pseudo-code example (transaction 1): begin transaction insert into messgae(id,col1,col2...) values(#id,#col1,#col2...); update thread set post_count=nvl(post_count,0) + 1 where id=#v_id; update test_user

What is the difference between OLAP and OLTP and what is data warehouse?

What is the difference between OLAP and OLTP and what is data warehouse?OLAP is usually called a data warehouse. However, data warehouses are only part of OLAP, not all.OLTP has more indexes than OLAP, and has high requirements on real-time performance, with many updates and modifications.OLAP usually queries and analyzes data that is rarely modified or updated.OLTP needs to observe three major paradigms to reflect data changes in real time and try to
