2、nd the kind of data returned by each type？What is the difference between a query filter and a report filter?What are the three components that make up a Web Intelligence document?What are the differences between applying breaks and sections to a report?What is a Scope of Analysis for a query?,SAPPHI

3、RE 2008 OR 4238/Page 5,习题答案：,1.What is a universe?Answer:A universe is the BusinessObjects semantic layer that maps to data in a database and is used for creating queries in Web Intelligence.2.List the object types used in a BusinessObjects universe,and the kind of data returned by each type.Answer:

4、Dimension objects:Character-type data,dates,and non-aggregated numeric data,for example telephone numbers.Dimensions are the key elements of a query.Measure objects:Numeric-or fact-type dataDetail objects:Character-or date-type data(supplementary information),SAPPHIRE 2008 OR 4238/Page 6,习题答案：,3.Wha

5、t is the difference between a query filter and a report filter?Answer:A query filter is created in the Query panel to limit the data retrieved from the database;a report filter is created in the Web Intelligence Rich Client window and allows you to restrict the data shown in the report simply by hid

6、ing the data you are not interested in.4.What are the three components that make up a Web Intelligence document?Answer:Reports,blocks(tables and charts),and the microcube of data,SAPPHIRE 2008 OR 4238/Page 7,习题答案：,5.What are the differences between applying breaks and sections to a report?Answer:The

7、 difference is that the grouped value appears as a header outside the block instead of remaining within the block.A break only groups within a block,whereas sectioning groups the entire report.,SAPPHIRE 2008 OR 4238/Page 8,习题答案：,6.What is a Scope of Analysis for a query?Answer:The scope of analysis

8、for a query is extra levels of data in an objects hierarchy that you can retrieve from the database to give more detailed data returned by each of the objects.This extra data does not appear in the initial document results,but it remains available in the data cube,or data provider,so you can pull th
