OLTP系统是设计用来允许高并发性的,这样很多用户就能够访问同一个数据源并进行所需的处理。 OLTP系统是面向在数据库上进行事务处理的理念的。而事务则进一步蕴含着发生在表中数据上的受控的变更,这些变更包括在商务运作过程中发生的插入、更新和删除操作。通常,一个OLTP系统将会有大量的客户端应用程序通过各种各样的方...

OLTP systems are optimized for fast and reliable transaction data processing, with a focus on data integrity. The data is typically stored in a normalized form to minimize data redundancy. Key Features Let's look at the key characteristics of OLTP system: Real-time processing:OLTP systems process...
DM(Data Mining):数据挖掘,又称为数据库中的知识发现(Knowledge Discovery in Database, KDD),就是从大量数据中获取有效的、新颖的、潜在有用的、最终可理解的模式的非平凡过程,简单的说,数据挖掘就是从大量数据中提取或“挖掘”知识。 4、ODS(Operating Data Store):操作性数据仓库,最早的数据仓库模型。特点是...
The main difference between OLAP and OLTP: Processing type The main distinction between the two systems is in their names: analytical vs. transactional. Each system is optimized for that type of processing. OLAP is optimized for conducting complex data analysis for smarter decision-making. OLAP sys...

OLAP vs. OLTP Online transaction processing, orOLTP, refers to data-processing methods and software focused on transaction-oriented data and applications. The main difference between OLAP and OLTP is in the name: OLAP is analytical in nature, and OLTP is transactional. ...
A query result is significantly smaller than the source data. In other words, data is filtered or aggregated, so the result fits in a single server’s RAM. It is easy to see that the OLAP scenario is very different from other popular scenarios (such as OLTP or Key-Value access). So ...
The term OLAP was created as a small modification of the normal info term OLTP (Online dealing Processing). Two leading OLAP merchandise square measure Titan Solution's Essbase and Oracle's categorical Server. OLAP merchandise square measure usually designed for multiple-user environments,...
