PostgreSQL 是一种非常复杂的对象-关系型数据库管理系统(ORDBMS),也是目前功能最强大,特性最丰富和最复杂的自由软件数据库系
一、简介
PostgreSQL 是一种非常复杂的对象-关系型数据库管理系统(ORDBMS),,也是目前功能最强大,特性最丰富和最复杂的自由软件数据库系统。有些特性甚至连商业数据库都不具备。这个起源于伯克利(BSD)的数据库研究计划目前已经衍生成一项国际开发项目,并且有非常广泛的用户。
二、系统环境
系统平台:CentOS release 6.3 (Final)
PostgreSQL 版本:PostgreSQL 9.2.4
防火墙已关闭/iptables: Firewall is not running.
SELINUX=disabled
三、安装方式
A. 下载RPM包安装
B. yum 安装
C. 源码包安装
四、安装过程
A. RPM包安装
1. 检查PostgreSQL 是否已经安装
[root@TS-DEV ~]# rpm -qa|grep postgres [root@TS-DEV ~]#若已经安装,则使用rpm -e 命令卸载。
2. 下载RPM包
#http:http:http://yum.postgresql.org/9.2/redhat/rhel-6-i386/postgresql92-9.2.4-1PGDG.rhel6.i686.rpm3. 安装PostgreSQL,注意安装顺序
# rpm -ivh postgresql92-libs-9.2.4-1PGDG.rhel6.i686.rpm# rpm -ivh postgresql92-9.2.4-1PGDG.rhel6.i686.rpm
# rpm -ivh postgresql92-server-9.2.4-1PGDG.rhel6.i686.rpm
# rpm -ivh postgresql92-contrib-9.2.4-1PGDG.rhel6.i686.rpm
4. 初始化PostgreSQL库
PostgreSQL 服务初次启动的时候会提示初始化。
5. 启动服务
# service postgresql-9.2 start6. 把PostgreSQL 服务加入到启动列表
# chkconfig postgresql # chkconfig --list|grep postgres7. 修改PostgreSQL数据库用户postgres的密码(注意不是linux系统帐号)
PostgreSQL数据库默认会创建一个postgres的数据库用户作为数据库的管理员,默认密码为空,我们需要修改为指定的密码,这里设定为’postgres’。
# su - postgres $ psql # ; # pg_shadow ;8. 测试数据库
8.1 创建测试数据库
# create database david;
8.2 切换到david 数据库
# \c david
8.3 创建测试表
david=# create table test ( id integer, name text);8.4 插入测试数据
david); david=#8.5 选择数据
david test ; id | name david (1 row) david=#测试成功。

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

MySQL/InnoDB supports four transaction isolation levels: ReadUncommitted, ReadCommitted, RepeatableRead and Serializable. 1.ReadUncommitted allows reading of uncommitted data, which may cause dirty reading. 2. ReadCommitted avoids dirty reading, but non-repeatable reading may occur. 3.RepeatableRead is the default level, avoiding dirty reading and non-repeatable reading, but phantom reading may occur. 4. Serializable avoids all concurrency problems but reduces concurrency. Choosing the appropriate isolation level requires balancing data consistency and performance requirements.

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.
