However, the table illustrates the purpose of using aggregate tables for faster queries If a user wants to analyze customer or product line sales only on a monthly or quarterly basis, the queries will run much faster against a 216 million row table than an 11497 billion row table

The existence of aggregate tables does not help user queries Users must access the summary tables, ideally automatically with awareness built into the RDBMS to force the query to be processed in the most efficient way You most often will use aggregates with measures from fact tables as shown in Figure 11-4 For extremely large dimensions, you also may have a smaller dimension table, for example, that removes dimension details lower than month and product line (as shown in Figure 11-3) The following process outlines the key steps to enabling aggregate awareness:
Creating Aggregate Fact Tables
Business Objects has provided two aggregate tables as part of the EFASHIONMDB You will focus on the one table:
AGG_YR_QT_MT_MN_WK_RG_CY_SN_SR_QT_MA
The naming of the table is a bit cumbersome, so hereafter, I will refer to it as the aggregate fact table The table name reveals some information on the contents of the table: AGG Aggregate YR Year QT MN WK Quarter Month Number Week MT Month Text
RG Maybe region was intended but it is not in the final table CY City SN Store Name SR Sales Revenue

Advanced Objects
QT MA
Quantity Margin
I do have some concerns with the design of this table, as it has a fair bit of dimensional information that is typically stored in separate tables, but for demonstration purposes it will work fine Notice that the number of rows for the aggregate table is 1982 compared to 89,171 in the detailed SHOP_FACTS table Whenever possible, you want queries to run against the smaller AGG_YR_QT_MT_MN_WK_RG_CY_SN_SR_QT_MA rather than the larger, detailed SHOP_FACTS
Identifying Dimension Tables Irrelevant to Aggregate Tables
In looking at Figure 11-5, you see that the aggregate table does not include any information on Articles So the dimension tables ARTICLE_LOOKUP and ARTICLE_COLOR_LOOKUP will become incompatible with the summary objects The fact table includes a lot of dimensional information Time information is aggregated to the week level You can retrieve dimensional information from either CALENDAR_YEAR_LOOKUP or the aggregate fact table Outlet information is not aggregated; the aggregate tables contain details on the STORE_NAME, which is at the same grain as the OUTLET_LOOKUP but does not contain information about the store location
PART II
Adding Aggregate Awareness to Measure Objects
You are now ready to define aggregate awareness to the individual measure objects Sales Revenue, Quantity Sold, and Margin Aggregate awareness uses an internal function Designer:
@Aggregate_Aware(sum(smallest_tablecolumn), sum(medium_tablecolumn), sum(biggest_tablecolumn))
FIGURE 11-5 A detail fact table and a summary aggregate table may share some of the same dimension tables
Part II:
A Better Universe
You can have multiple tables in the SELECT statement, with the smallest table first and the largest or most detailed table last The @Aggregate_Aware function allows you to use any of the SQL Aggregate commands (SUM, COUNT, AVG, MIN, MAX); however, the aggregate command must be specified for each column as shown here Right:
@Aggregate_Aware(sum(Agg_yr_qt_mt_mn_wk_rg_cy_sn_sr_qt_maSales_revenue), sum(Shop_factsAmount_sold))
Wrong:
@Aggregate_Aware(sum(Agg_yr_qt_mt_mn_wk_rg_cy_sn_sr_qt_maSales_revenue, Shop_factsAmount_sold))
NOTE If you normally have Designer automatically create objects when you add a table, turn this
feature off before adding aggregate tables: Choose Tools | Options | Database Remove the check mark from Create Default Classes And Objects From Tables You do not want separate objects from these tables Instead, you will point existing objects to access the aggregate tables To follow the steps, use the Test Fashion universe created in earlier chapters 1 Insert the aggregate table into the universe structure Click the Table Browser button or use the pull-down menu to select Insert | Table | AGG_YR_QT_MT_MN_ WK_RG_CY_SN_SR_QT_MA 2 Expand the class Test Fashion Measures 3 Select the object Sum of Amount Sold or Revenue 4 Click the >> next to sum(Shop_factsAmount_sold)to invoke the SQL Editor 5 If you wish to avoid re-creating the SQL for the detail SHOP_FACTS table, ensure your mouse is positioned at the start of the SQL statement 6 Under Functions, click the + sign next to @Functions to expand the group and display the Designer internal functions 7 Double-click @Aggregate_Aware to insert the syntax in the SQL statement box 8 Under Functions, click the + sign next to Number to display the SQL RDBMS functions Scroll to sum() and click to insert the syntax into the SQL statement 9 Under Tables And Columns, expand the aggregate table AGG_YR_QT_MT_MN_WK_ RG_CY_SN_SR_QT_MA and double-click SALES_REVENUE to insert the table column between the parentheses of sum() 10 Delete the right parenthesis and move it to the end to close the statement Your SQL statement should appear as follows:
