this means you need to design the database system in such a way that you divide the database tables into modularized and optimized partitions of two types -- static and dynamic.
这就意味着您需要以这样的方式设计数据库系统,即将数据库表划分成两种类型——静态和动态——的模块化、最优化部分。
but when you can design the database schema explicitly for your application, you often don't need a mapping framework.
但是当您能为应用程序显式地设计数据库模式时,您通常不需要映射框架了。
this requires to design the database module, including database designment, the employment of advanced connecting method ado and selection of database patterns.
这个功能需要设计数据库模块,包括数据库的设计、高级连接方式ado的实现和数据库模式的选用。
