Many organizations have an online transaction processing system. This type of system is characterized by: There are high data update activities that are typically performed by a large number of users. A large number of users concurrently access the database. The data is growing continuously. Examples of such applications are supermarket sales systems, air tic

Online analytical Processing Overview development background With the wide application of database technology, enterprise information system has produced a lot of data, how to extract information from these massive data to enterprise decision analysis is an important problem that the enterprise decision management personnel faces. The traditional Enterprise database system (MIS), which is the

transaction operations data resources, there must be other transactions at the same time access to the data resource, so lock the resource first. The general implementation is implemented by the database, using exclusive locks to lock resources. Using get (), load (), is the specified lock mode can be displayed: Lockmode.upgrade Session.get (Student.class,1,lockmode.upgrade); 6.

This article introduces the basic concepts of PostgreSQL's transaction processing function, and explains how to execute various transactions through the PostgreSQL client and from the PHP script. Through this article, you will learn what transaction

The concept of online analytical processing (OLAP) was first proposed by the father of the relational database, E.f.codd, in 1993, and he also presented 12 guidelines on OLAP. OLAP has aroused a great deal of response, OLAP as a class of products and online transaction processing
