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

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

Mondrian is an open-source project. An OLAP (Online Analytical Processing) engine written in Java. It implements queries using the MDX language and reads data from relational databases (RDBMS. The results are displayed in multiple dimensions through Java APIs. We all know that Online Analytical Processing (OLAP) needs to analyze a large amount of data in real time. The term "online" means that the system mu

Today's 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).

OLAP is the main application of Data Warehouse system, sup

OLAP (on-line analysis processing)It is a kind of software technology that enables analysts, administrators, or executors to quickly, consistently, and interactively access information from multiple perspectives to gain a deeper understanding of data. OLAP is designed to meet decision-making support or specific query and report requirements in multi-dimensional environments. Its core technology is the conce

Cloveretl Cloveretl is a data ETL framework that extracts business data and converts it to the type required by OLAP. It is still stored in relational databases. Typically, the order and orderitem tables in the parent-child relationship need to be converted into a fact table. In orderitem, a large amount of redundant order data, such as date, customer, and branch, is required for statistics convenience. It seems that this is only a few lines in the c

SQL Server skills: how to monitor and optimize OLAP Databases It is very important to optimize the performance of online analysis and processing. Fortunately, some tools can help monitor and improve the operation of OLAP databases. The Microsoft SQL Server Analysis Service (SSAS) provides a powerful engine used to create and manage data mining applications and online analysis and processing systems. To ac
