"DB2 Family Fundamental" DB2是IBM推出的一款关系型数据库管理系统,它广泛应用于各种操作系统环境,包括z/OS和OS/390。本资源主要关注DB2家族的基础知识,涵盖数据库的设置、参照完整性的概念、数据的输入与输出、以及程序准备与绑定等关键领域。 在“Setting up a DB2 Database”部分,我们将学习如何建立一个DB2数据库。这通常涉及创建必要的存储结构,如存储组和表空间。存储组是一组DASD(直接访问存储设备)卷,DB2可以从这些卷中分配空间来创建表空间和索引空间。数据库则是一个由表空间和索引空间组成的集合,旨在方便管理和安全操作。 表空间是外部存储区域,用于存储一个或多个表的记录。而索引空间是用于存储单个索引条目的外部存储区域。索引是有序的键值集合,包含指向含有这些键的行的指针,能显著提升数据查询的效率。 "Referential Integrity"涉及到保持数据库中数据的一致性和完整性,这是通过定义外键约束来实现的,确保了数据之间的关联不会被破坏。 "Getting Data into and out of DB2"涵盖了数据导入导出的方法,可能包括SQL插入语句、加载工具或其他数据迁移工具,以确保数据可以顺利地在DB2和其他系统间流动。 "Keeping Your DB2 Data in Good Shape"强调了数据库维护,这可能包括定期备份、性能监控、故障恢复策略以及数据库的优化。 在"Program Preparation / Bind"环节,我们学习如何准备和绑定应用程序,这是将编译后的程序与数据库接口连接的过程,确保程序能正确访问和操作数据库中的数据。 此外,资源还提到了数据库对象的一些概念,如视图、同义词和别名。视图是通过SELECT语句定义的虚拟表,它可以显示一个或多个表的部分或全部行和列。同义词是本地表的私有别名,而别名则是系统范围内的表别名,可以用于本地或远程表,它们提供了对数据库对象的便捷引用。 DB2 Family Fundamental是理解DB2数据库管理基础的关键资源,涵盖了从数据库架构到数据操作,再到程序集成的各个方面,对于DB2初学者和管理员都具有很高的参考价值。
