OLTP: on-line transaction processing online transaction processing system, also known as a transaction-oriented processing system. Its basic feature is that customers' raw data can be immediately transmitted to the Computing Center for processing, the processing result is provided in a short time. OLAP: On-lineanalyticalprocessing online analysis and processing system. The data converted from the raw data that truly understands the user and truly ref

I'm not going to introduce the concepts of OLTP and OLAP here, and these are the same DBAs that are required to understand. Today's topic is why binding variables fit in OLTP systems rather than OLAP systems. In some ways, we can look at OLTP and OLAP systems like this, OLTP system small query many and OLAP systems are

The difference between OLAP and OLTP and what is Data Warehouse OLAP is often referred to as a data warehouse. But the data warehouse is only part of OLAP, not all. OLTP multi-index than OLAP, and the real-time requirements of high, updated and modified many. OLAP generally seldom modifies and updates data, and so on, usually query and analysis. OLTP needs to adh

OLTP performance adjustment and optimization-conclusion According to the waterfall model of the software life cycle, the performance of an application has been qualitative in its design stage. If you think of optimization only after the application development is complete, you can only cure the problem. In the case of serious performance problems, you even need to re-launch the entire software. When a software system has been launched for operation an

Online Transaction Processing OLTP (on-line transaction processing) OLTP is the main application of traditional relational databases, mainly for basic and daily transaction processing, such as bank transactions. OLAP (on-line analytical processing) OLAP is the main application of the data warehouse system. It supports complex analysis operations, focuses on decision support, and provides intuitive and easy

In a variety of test mix scenarios, the combination of 10 (combination 10:SSD * 2, RAID 0, Xfs,wb,nobarrier,noop) has the highest overall performance, so it is the benchmark, and the comparison of other schemes, the following table is the comparison of the combinations and combinations 10:650) this.width=650; "Src=" http://dp.imysql.com:8080/files/upload_yejr_imysql/SAS_VS_SSD_MySQL_OLTP%E5%AF%B9%E6% Af%94%e6%b5%8b%e8%af%95%e8%a1%a8-20120907.png "style=" border:0px; "alt=" sas_vs_ssd_mysql_oltp%

OLAP (On-line Analytical Processing) online analytical processing, also known as transaction-oriented processing, is characterized by the fact that the user data received by the foreground can be transferred immediately to the computing center for processing and the processing results are given in a very short period of time. is one of the ways to quickly respond to user actions.OLTP (on-line Transaction processing) online transaction processing, which enables analysts to quickly, consistently a

SQL Server 2014 introduces a memory database, which is a very good function. Data can be directly stored in the memory, which can be operated directly on the memory, greatly improving the performance. Today, I think of a problem. What happens if the table grows bigger and the database memory is insufficient. Because Microsoft's msdns writes the following content: A computer with enough memory to hold the d

theories that have been instilled so far and explain the reasons and usage of these theories first.Different types of database models should be adjusted in different ways. Generally, you can adjust the database model according to the application requirements of the dependent database. This is due to the needs of end users. Two extreme cases of this Division are

cache again. This operation is called Reload. Generally, Reload is irrelevant to Get, because Reload occurs only after the object is invalid, and the invalid object does not affect the object handle. Okay. Now let's take a look at the meaning of these values.We have already talked about Get, Pin and their hit and miss, and what are Invalidation and Reload. In the OLTP system, the Get hit rate should be above 90%. The ratio of Reload to Pin times shou
