In a project, system stability and high availability must be achieved according to user requirements. In the original solution, dual-machine hot backup is planned. At the beginning of the solution, it would be so troublesome and too optimistic that ArcSde + Oracle dual-machine hot backup was not implemented. I felt that it could be completed through the information. Because dual-nic and heartbeat settings are required, normal environments cannot be tested. I want to experiment in the user's envi

From: http://database.csdn.net/page/b12503e6-9f14-4cc1-90dd-88632444a46e In the Web 2.0 era, websites often face a rapid increase in access traffic. However, how can our applications meet users' access needs, in addition, we can basically see that performance bottlenecks are all on the database. This is not to blame for the database. After all, it is indeed a great pressure on any database to meet a large amount of traffic, whether it is a commercial database such as Oracle, MS SQL Server, DB2,

Databases are designed for transactions and data warehouses are designed for topics. Databases generally store online transaction data, while data warehouses generally store historical data. Database Design is designed to avoid redundancy as much as possible. Generally, it is designed to comply with the rules of the paradigm. Data Warehouse design is intended to introduce redundancy and adopt an anti-paradi

The customer's two IBM Power 740 minicomputers use the HACMP software to create database servers with mutual standby relationships. Each minicomputer runs a database, and any server fails, another minicomputer should take over the database immediately and take over the database together. At this time, two databases run on one minicomputer. After the faulty server returns to normal, the corresponding database will automatically switch back to the host.

Basic concepts of Android databases (I) and basic concepts of android 1.

SQLite databases can store application data in a structured and easy-to-manage way. Android provides a complete library file for SQLite relational

At present, computer technology has been widely used in various fields of the national economy. While computer hardware is constantly miniaturization, application systems are gradually becoming more complicated and larger. Database is the core of the entire system. Its design is directly related to the efficiency of system execution and system stability. Therefore, in software system development, database design should follow the necessary database Paradigm Theory to reduce redundancy and ensure

Label:relational databases and non-relational databasesThe difference between a relational database and a non-relational database is that a relational database has only a data structure that is "tables", and not a relational database system has other data structures that have other operations on them. With the continuous development of the network, the simple relational database faces the challenge.Characteristics of relational and non-relational

Welcome to the Windows community forum and interact with 3 million technical staff for a recent internship. The company's server has more than a dozen databases.
