这一方式具备的明显优势就是能够减少数据库调用,从而减少事务负载,更快地访问网格(grid)中的对象。
Using Informix 4GL's rich language support, it is easy to implement the user interface and the business logic that might involve embedding the SQL statements to access the database objects.
通过使用Informix4GL丰富的语言支持,可以轻松地实现用户界面和业务逻辑,还可以在其中嵌入用于访问数据库对象的SQL语句。
Controlling access to database objects using schemas.
使用模式控制对数据库对象的访问。
Database-driven objectization (DDO): Select a table and to generate the objects for data access and manipulation, otherwise referred to as CRUD (create, replace, update, delete).
Database-drivenobjectization (DDO):JLINQ最常用的用法就是选择一个表,为数据访问与操作生成对应的对象,或是对其进行CRUD的操作。
PureQuery data access objects using annotated methods are designed specifically to support both dynamic and static database access.
带注释的方法风格是专门为同时支持动态和静态数据库访问而设计的。
The DBADM authority allows a user to perform administrative tasks on a specific database in an instance and allows full access to the data and objects in that database.
DBADM权限允许用户在一个实例中的特定数据库上执行管理任务,还允许完全访问这个数据库中的数据和对象。
Once the mapping is done, you can manipulate mapped objects as normal objects and easily submit changes back to relational database without writing complex data access logic.
一旦完成映射,您就可以将他们当成普通对象来处理,无需编写复杂的数据访问逻辑就可以轻松地将更改提交回数据库。
This does not imply that the user has direct access to the underlying database objects.
这意味着用户不能直接访问底层数据库对象。
This is yet another example demonstrating that LINQ is not a framework to access just data in a database but it can be used with all sorts of objects, including tweets.
这个示例再一次证明了LINQ不仅仅是一个访问数据库的框架,它可以用于任何类型的对象,包括tweet。
Increased disk utilisation also occurs if events and actions require access to a user database (for example, database fetches in intermediate objects for event and action augmentation).
事件和动作需要访问用户数据库还会导致磁盘使用率增加(例如,数据库获取中间对象导致事件和动作增加)。
Data logic and business rules can be encapsulated so that users can access data and objects only in ways that developers and database administrators intend.
可以包装数据逻辑和业务规则,以便用户可以仅通过开发人员和数据库管理员打算使用的方式访问数据和对象。
