Oracle biee12c新功能介绍
ORACLE 12c新特性 可插拔
Oracle 12C引入了CDB与PDB的新特性，在ORACLE 12C数据库引入的多租用户环境（Multitenant Environment）中，允许一个数据库容器（CDB）承载多个可插拔数据库（PDB）。
CDB全称为Container Database，中文翻译为数据库容器，PDB全称为Pluggable Database，即可插拔数据库。
在ORACLE 12C之前，实例与数据库是一对一或多对一关系（RAC）：即一个实例只能与一个数据库相关联，数据库可以被多个实例所加载。
而实例与数据库不可能是一对多的关系。
当进入ORACLE 12C后，实例与数据库可以是一对多的关系。
下面是官方文档关于CDB与PDB的关系图。
其实大家如果对SQL SERVER比较熟悉的话，这种CDB与PDB是不是感觉和SQL SERVER的单实例多数据库架构是一回事呢。
像PDB$SEED可以看成是master、msdb等系统数据库，PDBS可以看成用户创建的数据库。
而可插拔的概念与SQL SERVER中的用户数据库的分离、附加其实就是那么一回事。
看来ORACLE也“抄袭”了一把SQL SERVER 的概念，只是改头换面的包装了一番。
CDB组件（Components of a CDB）一个CDB数据库容器包含了下面一些组件：ROOT组件ROOT又叫CDB$ROOT, 存储着ORACLE提供的元数据和Common User,元数据的一个例子是ORACLE提供的PL/SQL包的源代码，Common User 是指在每个容器中都存在的用户。
SEED组件Seed又叫PDB$SEED,这个是你创建PDBS数据库的模板，你不能在Seed中添加或修改一个对象。
一个CDB中有且只能有一个Seed. 这个感念，个人感觉非常类似SQL SERVER中的model数据库。
PDBSCDB中可以有一个或多个PDBS，PDBS向后兼容，可以像以前在数据库中那样操作PDBS，这里指大多数常规操作。

Oracle Database 12c十二大新特性
作为甲骨文全球大会OpenWorld 2012中的重要产品发布，新版Oracle Database 12c汇集了参会者最多的目光，Larry Ellison也在开幕演讲中重点介绍了12c 的一些新特性。
对于Oracle DBA来说，虽然数据库12c正式发布的日期还要等到明年年初，但依旧希望能够提前了解它的一些新功能、新特性。
在OpenWorld 2012的技术讲座环节，Oracle技术大师Tom Kyte集中介绍了Oracle Database 12c的十二大新特性，而Oracle ACE总监杨廷琨也对此进行了总结，希望让国内DBA一睹为快。
1.PL/SQL性能增强：类似在匿名块中定义过程，现在可以通过WITH语句在SQL中定义一个函数，采用这种方式可以提高SQL调用的性能。
2.改善Defaults：包括序列作为默认值;自增列;当明确插入NULL时指定默认值;METADATA-ONLY default值指的是增加一个新列时指定的默认值，和11g 中的区别在于，11g的default值要求NOT NULL列。
3.放宽多种数据类型长度限制：增加了VARCHAR2、NVARCHAR2和RAW类型的长度到32K，要求兼容性设置为12.0.0.0以上，且设置了初始化参数MAX_SQL_STRING_SIZE为EXTENDED，这个功能不支持CLUSTER表和索引组织表;最后这个功能并不是真正改变了VARCHAR2的限制，而是通过OUT OF LINE的CLOB 实现。
4.TOP N的语句实现：在SELECT语句中使用“FETCH next N rows”或者“OFFSET”，可以指定前N条或前百分之多少的记录。
5.行模式匹配：类似分析函数的功能，可以在行间进行匹配判断并进行计算。
在SQL中新的模式匹配语句是“match_recognize”。
6.分区改进：Oracle Database 12c中对分区功能做了较多的调整，Oracle ACE总监杨廷琨花了较大的篇幅对分区提升进行了解读，其中共分成6个部分：INTERVAL-REFERENCE分区：把11g的interval分区和reference分区结合，这样主表自动增加一个分区后，所有的子表、孙子表、重孙子表、重重重...孙子表都可以自动随着外接列新数据增加，自动创建新的分区。
