The DeepSee Model 3.7.1 Measures Measures refer to source data and aggregate it. That is, a given cell in a pivot table corresponds to specific records in the database. If that cell displays a measure, the measure uses a specific field in those records and gets all the values of that field (one value in each of the associated records). It then aggregates those values and displays the result. DeepSee provides a set of aggregation functions, including sum, minimum and maximum, average, first date and last date. Measures can be used only as columns. 3.7.2 Computations In contrast to measures, computations refer to data in other cells of the pivot table and use that data to compute a related number. The expression for a computation uses Caché ObjectScript. A large selection of functions, macros, and special variables is available, and you can use any Caché ObjectScript expression. For example, you can create computations that do the following: • Compute the difference between two columns or two rows • Compute a cumulative total • Divide one column by another and display as a percentage • Use If-Then-Else logic to determine which number to display • Compute the total value shown in another column or row (or use this total within a more complex calculation) Computations can be used as rows or as columns. 3.7.3 Automatically Created Measures and Computations DeepSee automatically creates the following measures and computations: • The Count measure is simply a count of the records in the base class (in this case, User.Orders), automatically aggregated as a sum. • In addition, a cube automatically provides a measure corresponding to each numeric dimension. Any such measure is automatically aggregated as a sum. • The Total computation provides a total. When you use this computation as a row, a given cell displays the sum of all values in the column, as shown in the example after this list. When you use this computation as a column, a given cell displays the sum of all values in the row. 22 Introduction to InterSystems DeepSee
Measures and Computations • The Average computation displays the average value of a column or row, in the same way. That is, when you use it as a row, a given cell displays the average of all values in the column. When you use it as a column, a given cell displays the average of all values in the row. • The Forecast computation displays a forecast value, in the same way. The forecast is calculated as the moving average of the numbers. 3.7.4 Custom Measures and Computations You can create any custom measures and computations you need. You can define them within a subject area, which makes their initial definitions available to anyone working in that subject area. Or you can create them locally within a given pivot table. You could create custom measures and computations such as the following: • Running totals. • Backlog calculations. • Average number of days since a particular event. • Number of associated items. For example, a custom measure could indicate the number of lab tests or the number of types of tests. • Expressions using Caché ObjectScript. Introduction to InterSystems DeepSee 23
