首页Oracle数据库参考指南10.2版
"Oracle Database Reference 10.2.pdf 是一本关于Oracle数据库的详细参考指南,涵盖10.2版本的特性和功能。这本书由Kathy Rich作为主要作者,并有多位专家共同贡献,旨在为用户提供Oracle数据库的全面技术信息。"
Oracle数据库是世界上最广泛使用的数据库管理系统之一,尤其在企业级应用中占据重要地位。Oracle Database 10.2版是Oracle公司的一个重要里程碑,它引入了许多新的特性和改进,以提高性能、可用性和管理效率。
1. **数据存储与管理**:Oracle 10.2提供了一种更高效的数据存储结构,包括分区表、索引组织表和物化视图,以及优化的存储管理策略,如自动存储管理(Automatic Storage Management, ASM),使得数据库管理员可以更方便地管理和优化存储资源。
2. **性能增强**:此版本引入了SQL优化改进,例如CBO(Cost-Based Optimizer)的增强,以及高级统计信息收集,帮助查询执行计划选择最佳路径。此外,快速恢复区(Fast Recovery Area, FRA)的引入增强了故障恢复和备份的效率。
3. **高可用性**:Oracle数据库10.2提供了更强大的高可用性解决方案,如Data Guard、Real Application Clusters (RAC) 和Standby数据库,确保在系统故障时能够快速切换和恢复服务。
4. **安全管理**:这一版本加强了权限和角色管理,增加了细粒度审计和数据加密功能,以保护敏感信息。
5. **网格计算支持**:Oracle 10g强调网格计算能力,10.2版允许数据库在分布式计算环境中无缝运行,通过Grid Infrastructure实现资源的集中管理和调度。
6. **XML支持**:Oracle数据库10.2对XML数据类型进行了增强,支持XMLDB(XML数据库),允许直接在数据库中存储和处理XML文档。
7. **PL/SQL改进**:PL/SQL编程语言在10.2中也得到了提升,包括新的包、过程和函数,以及调试和性能优化工具。
8. **企业管理**:Oracle Enterprise Manager 10g 提供了更强大的数据库监控和管理工具,使得DBA可以更有效地管理大规模的数据库环境。
9. **开发工具集成**:Oracle 10.2与多种开发工具(如JDBC,ODBC,Oracle JDeveloper等)有良好的集成,便于开发人员进行应用程序开发。
10. **全球化支持**:Oracle 10.2支持多语言环境,包括字符集的增强,确保全球用户都能顺利使用。
《Oracle Database Reference 10.2》是数据库管理员、开发人员和系统架构师不可或缺的参考资料,它深入介绍了Oracle 10.2的各项功能,帮助用户充分利用这个强大数据库系统的能力。
