INTERBASE 6.5 FEATURE LIST (IB6.5的新特性列表)
龙豪软件工作室(3ASoft Studio) / 唐辉
Metadata Security (MetaData 安全性)
This new feature protects the metadata from modification by unauthorized users. Previous versions of InterBase have allowed any user to query and modify the system tables directly.
(这一新特性将保护MetaData数据不能被未授权的用户改动;而前期版本就允许用户查询和修改系统表数据。)
64 Bit file I/O (64位文件I/O)
InterBase 6.5 now supports the creation of database files greater than 4 GB. In previous versions of InterBase to support files sizes greater than 4 GB one had to create multi-file databases.
(IB6.5现在支持大于4GB的数据库文件,而前期版本的IB要支持大于4G的数据文件,必需建立基于多个文件的数据库文件。)
Asynchronous Cancel (异步终止)
The ability to cancel an executing DSQL statement is an often requested feature that is now included in InterBase 6.5. This feature modifies an existing DSQL API to request that a statement have its execution cancelled and interrupted.
(新版本的IB能够终止一个正在执行的DSQL语句。些特性通过修改一个已有的DSQL API,来请求一个语句的执行被终止。)
SQL Data Manipulation (ROWS clause) (SQL 的数据操作 (ROWS 语句))
The ROWS clause is used in conjunction with the SQL ORDER BY clause to provide a ranking capability for SQL queries.
(ROWS语句如果与SQL的ORDER BY语句连用,将提供一个ranking功能在SQL查询中。)
New isc_config/ibconfig File Parameters (新的isc_config/ibconfig文件参数)
CPU_AFFINITY, SWEEP_QUANTUM, USER_QUANTUM, and SWEEP_YIELD_TIME.
(在新版本IB中,新增了CPU_AFFINITY,SWEEP_QUANTUM,USER_QUANTUM以及SWEEP_YIELD_TIME 几个文件参数)
XML Generation (XML文档的产生)
This feature allows InterBase customers to generate XML documents directly from InterBase without having to learn anything new about XML. We have added 2 new API calls isc_dsql_xml_fetch() and isc_dsql_xml_fetch_all(), which are used by client to create the XML file.
(这一特性允许 InterBase 用户从IB中直接生成XML文档,而无需学习任何新的XML。新版本中共增加了两个API函数isc_dsql_xml_fetch()和isc_dsql_xml_fetch_all(),供客户端调用用于生成XML文档。)
New JDBC Methods (新的 JDBC 方法)
This feature has been implemented so that now the InterClient code is up to date with the latest shipping JREs (1.3). The only requirement for the implementation of this functionality is the existence of Java 2 on the platform. This implementation allows InterBase to be stronger now that the code has moved to the most currently maintained JRE.
(新特性最终是为了实现 InterClient 代码与最新的JREs(1.3)相匹配。这仅仅要求所运行的平台上安装Java 2就可以了。此特性可以将代码移植到最新的JRE上,从而使 InterBase 数据库更加完善与健壮。)
