The ORACLE tutorial is: Modeling and Design of Oracle databases. To develop a database-based application system, the most critical step is the database modeling design on which the entire system is based. From logical to physical, the design is neglected in one link, the ent

Oracle is recognized as the most secure database system. Enterprise-level Oracle database application systems include system hardware, operating systems, network layers, and DBMS database management systems), applications, and data. Each part is mutually dependent, each part must be properly configured, designed, and optimized to achieve a high-performance database system. This article discusses some experi

A complete database system includes system hardware, operating system, network layer, DBMS (Database Management System), applications, and data. Each par

First, IntroductionUltra-large systems are characterized by:1. The number of users to deal with is generally more than million, and some more than tens of millions of data, the database generally more than 1TB;2. The system must provide real-time response function, the system needs to operate without downtime, requiring a high availability and scalability of the system.In order to meet the above requirements, in addition to the need for superior performance of the computer and mass storage equip

As we all know, the quality of database design is directly related to the efficiency of database operation. According to the author's experience, to enhance the database performance, reasonable database design, than upgrade the server hardware configuration, but also to come effective. However, the author whether in cooperation with colleagues, or in the forum wi

We will teach you the followingLarge Oracle DatabaseDesign method, hope to help you. 1. Features of super large systems: 1. Generally, the number of users processed exceeds 1 million, and the number of users processed exceeds 10 million. The data volume of the database generally exceeds 1 TB; 2. The system must provide the real-time response function. The system must run without stopping services, requiring high availability and scalability of the sys

high availability and scalability of the system. In order to meet the above requirements, in addition to computers with superior performance and massive storage devices, advanced database structure design and optimization application systems are also required. Generally, super-large systems use dual-host or multi-host Cluster Systems. The following uses the Oracle 8.0.6 Parallel Server as an example to des

Oracle Database pioneered the design concept of tablespace, which makes an indelible contribution to the high performance of Oracle Database. In this case, many Oracle optimizations are implemented based on the tablespace design concept. Typical application 1: control the ta

I. IntroductionSuper Large systems have the following features:1. Generally, the number of users processed exceeds 1 million, and the number of users processed exceeds 10 million. The data volume of the database generally exceeds 1 TB;2. The system must provide the real-time response function. The system must run without stopping services, requiring high availability and scalability of the system.In order to meet the above requirements, in addition to computers with superior performance and mass

Table indexes are almost the most effective way to improve the performance of data table query, Oracle has a rich type of data table index type, it is particularly important to choose the choice. In this article, we will focus on the index of the datasheet and will also mention the other two points. Through the analysis of a simple

The following articles mainly introduce the five specific requirements of Oracle Database in design standardization. Today we mainly introduce the first two requirements, we should avoid empty columns in the table, and avoid repeated values or column content in the table. In general, we can judge from two aspects whether the Oracle database is designed with a com

The greatest difference between an SQL Server database and an Oracle database is the tablespace design. Oracle Database pioneered the design concept of tablespace, which makes an indelible contribution to the high performance of Oracle Database. In this case, many

If the system follows the first paradigm, it is as follows: Create Table Studentcourse (stuid Number Primary Key , Stuname Varchar2 ( 20 ) Not Null , Cname Varchar2 ( 50 ) Not Null , Credit Number Not Null , Score Number ); Insert Into Studentcourse (stuid, stuname, cname, credit, score) Values ( 1 , 'Zhang san', 'java ', 3 , 89 ); Insert Into Studentcourse (stuid, stuname, cname, credit, score) Values ( 2 , 'Lily', 'java ', 3 , 99 ); I

In general, we mainly judge whether the design of the Oracle database is standardized from two main aspects. The first is to check the number of narrow tables, and the second is to check the number of tables. The actual number of wide tables. If the two conditions are met, the standardization level of the database is still relatively high. Of course, these are two general indicators. To meet the requirement
