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
from data warehouse is the biggest purpose of establishing data warehouse and using data mining. The essence and process of both are two things. In other words, data warehousing should be established first, and data mining can be carried out efficiently, because the data contained in the Data Warehousing itself is clean (No erroneous data involved) and complete, and integrated. Therefore, the relationship between the two may be interpreted as "Data Mining is a process and technology for finding
First, set OLAP, which can be accessed by machines in the LAN through the HTTP protocol. Then, use Excel to connect to OLAP through HTTP. The settings are as follows: 1. Create an OLAP site 1. Find the c: \ Program Files \ Microsoft SQL Server \ msas10.mssqlserver \ OLAP \ bin \ ISAPI Directory, which contains two fi
a normalization of the star mode.. In snowflake mode, dimension tables in star mode are further layered. The original dimension tables may be extended to small fact tables to form partial "hierarchical" areas.It minimizes data storage and combines smaller dimension tables to improve query performance. The snowflake mode increases the number of tables that users must process and the complexity of some queries. But this can make the system more professional and practical, while reducing the gene
Abstract: Based on the Data Storage Technology of ODS in the middle layer of DB and DW, a real-time OLAP system for commercial systems is designed from the perspective of application. ODS is used to overcome the problem that DW is too bloated for decision-making and is not suitable for enterprises' real-time middle-level decision-making. Key words: Data Warehouse (DW), operational data storage (ODS), Real-Time Online Analytical Processing (
OLAP (on-line analysis processing) enables analysts, administrators, or administrators to quickly, consistently, and interactively access information from multiple perspectives, this gives you a better understanding of the data. OLAP is designed to meet decision-making support or specific query and report requirements in multi-dimensional environments. Its core technology is the concept of "dimension. Dimen
throughput is often dependent on the number of disks, this time, Cache basically no effect, the database read-write type is basically db file scattered read with direct path read/write . Should try to use more than the number of disks and relatively large bandwidth, such as 4Gb the fiber interface.In the OLAP system, partitioning technology and parallel technology are often used.The importance of partitioning technology in the
Some basic knowledge about OLAP and OLTP Http://www.searchdatabase.com.cn/ShowContent_9526.htm Guidance:ArticleThis section describes some basic knowledge about OLAP and OLTP. Keywords: olap oltp basic knowledge Loading data... OLTP: on_line transaction processing online transaction processing OLAP
Online transaction Processing OLTP (on-line transaction processing) primarily performs basic, daily transaction processing , such as the increase, deletion, modification, and checking of database records . For example, in a bank to access a payment, is a transaction transaction. The features of OLTP typically include:1. High real-time requirements;2. The amount of data is not very large;3. Transactions are generally deterministic, so OLTP is access to definitive data (e.g., deposit and withdrawa
Oltp:on_line Transaction processing online transaction processing Olap:on_line Analytical processing online Analytical processing OLTP, as its name suggests, focuses on business processes. OLAP is specially designed to support complex analysis operations, focusing on decision support for decision makers and senior managers, it is possible to quickly and flexibly perform complex query processing of large amounts of data, and provide the query results
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
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
data sources; Time-Varying: data storage provides information from a historical perspective (such as the past 5 to 10 years); Non-Easy: Data Warehouses are physically separated to store data (It only requires two data access operations: data initialization and data access) Data Warehouses support on-line analytical processing, which is different from operating databases.Supported online transaction processing (on-line transaction processing ). Note: distinguish OLTP from
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
Some practical tips for using OLAP functions The online analytical Processing,olap function is very flexible and powerful. By using these functions, you can find a simple solution for some problems that are either to iterate over one or more cursors, or to be recursive. In some other cases, it is much easier to use OLAP functions or auxiliary tables than to not

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
In 1960s, E. F. codd, the father of relational databases, proposed a relational model to promote the development of online transaction processing (OLTP) (data is stored in the form of tables rather than files ). 1993, E. f. codd proposed the OLAP concept, and believed that OLTP could not meet the needs of end users for database query and analysis, and SQL for simple query of large databases could not meet the requirements of end users for analysis.
