data access object

基本解释

For example, the transfer object, business object, and data access object templates may be applied to each entity in the PIM.
举例来说，传递对象、业务对象，和数据访问对象模板将应用于 PIM 中的每个实体。
Applying the Data Access Object (DAO) pattern throughout the applications enabled us to separate low-level data access logic from business logic.
在整个应用程序中使用数据访问对象(DAO)使我们可以将底层数据访问逻辑与业务逻辑分离开来。
If the application uses a DAO (data access object) with dynamic SQLs and stored procedures, the value object that is passed to DAO can be declared as a cloud resource using annotations.
如果应用程序使用 DAO（数据访问对象）来产生动态 SQL 和存储过程，那么传递给 DAO 的值对象就可以使用注释声明为一种云资源。

As long as you have access to data through some data tool (like Tableau, Spotfire, Pentahoe, Splunk, Microstrategy, Business Object etc), you can download the data into excel to analyze.
