Pivot tables are a convenient method to summarise how many entries in a set of data have each combination of values for two attributes of interest. For example:
ID
Name
Responsibility
Status
UR-1
Sample requirement
Customer
Agreed
UR-2
An example requirement
Developer
Disputed
UR-3
Other requirement
New
UR-4
Another requirement
UR-5
UR-6
Other sample requirement
Referred
UR-7
Yet another sample requirement
UR-8
One more requirement
UR-9
A new requirement
UR-10
An old requirement
A pivot table can summarise the numbers of requirements with each combination of Responsibility and Status:
TOTALS
2
1
3
0
6
4
10
This shows:
The overall total shown in the bottom-right corner will always equal the number of items being summarised, 10 in this case.
Cradle fully supports pivot tables, which can be defined using any appropriate pair of attributes for all types of information, including all user-defined item types. Pivot tables can be published from Cradle custom web UIs and into the WorkBench non-web UI. Pivot tables can be published to external files in CSV, RTF (for Word and Write) and HTML (for web browsers, Excel and Calc).
In its pivot tables, Cradle includes all of the possible values for the attributes being analysed, and also:
In Cradle, each non-zero cell in a pivot table is a link to the items that have the corresponding combination of attribute values. You can select such links to open a new tab containing a list of the items with the corresponding combination of attribute values.
You can reference pivot tables in reports and in the phase hierarchy. You can generate them from the c_table command line utility. You can also generate them in documents produced by the Document Publisher tool.
Pivot tables are a type of metric, so a Cradle-MET licence is needed to define, generate and publish them.
