Starting Point
 Given this exemplar:

3
®
Destination
 We want to produce:

4
®
Establish mapping
 Some mappings are
obvious
 Some are not

5
®
How the pieces fit together:
 Capability relates to Operational Capability Realization
 Capability Operational Capability (Association)
 Operational Capability Realization relates to Operational Capability
 Realized Operational Capability (Realization)
 Operational Activities relate to Operational Capability
 containment
 System relates to System Operational Capability
 Capability Operational Capability (Association)
 System Operational Capability relates to System Capability
 Realized Operational Capability (Realization)
 Operational Activities relate to System Capabilities
 Activity Realization (Association)
 System Functions relate to System Capability
 Containment

6
®
Problem statement
 Find the capabilities that relate to systems by determining which operational
capabilities map to system operational capabilities via the operational activities
that are realized by the system functions.
 In the DoDAF domain, it’s the mapping of the operational to the system views.

7
®
First Query
 Create table that relates Capabilities (that are Operational Nodes) to
Operational Capabilities

8
®
BIRT – first query details
 Establish the data source
 Include the model (s)
 Include the necessary profile(s) (in this example, UPIA)
 Create a data set
 Row
 Extract all the Capability Operational Capability associations that relate
Capabilities (that are Operational Nodes) to Operational Capabilities
 Columns:
 Name of the Capability/OpNode
 URI of the Capability/OpNode
 Name of the Operational Capability
 URI of the Operational Capability

9
®
Establish the Data Source

10
®
Create the first data set row mapping

11
®
Specify the columns
 Discussion point: The sample model uses the Capability stereotype for both
Operational Nodes and Systems. In this query, we only want the Capabilities
that are Operational Nodes.
 We know that one end of the relationship is a Capability and the other is an
Operational Capability just from the semantics of the
CapabilityOperationalCapability definition.

12
®
Filter out the Capabilities that aren’t Operational Nodes

13
®
Validate the query

14
®
Second Query
 Create table that relates Operational Capabilities to Operational Capability
Realizations

15
®
BIRT – second query details
 Row
Extract all the Realized Operational Capability relationships
 Column
Name of the Operational Capability
URI of the Operational Capability
Name of the Operational Capability Realization
URI of the Operational Capability Realization

16
®
Establish the second query row mapping

17
®
Specify the columns

18
®
Validate the query

19
®
Third Query
 Create table that relates Systems to Operational Capabilities via Capability
Operational Capability associations

20
®
BIRT – details
 Create a data set
 Row
 Extract all the Capability Operational Capability associations that relate Systems
to Operational Capabilities
 Columns:
 Name of the System
 URI of the System
 Name of the Operational Capability
 URI of the Operational Capability

21
®
Create the row mapping

22
®
Create the column mapping

23
®
Filter out non-Systems

24
®
Validate query

25
®
BIRT – create the fourth query
 Row
Extract all the system functions
 Columns
Name of the system function
URI of the system function
Name of the system function owner
URI of the system function owner

26
®
Create the row mapping

27
®

28
®
Validate the query

29
®
BIRT – create the fifth query
 Row
Extract all operational activities
 Column
Name of the operational activity
URI of the operational activity
Name of the operational activity owner
URI of the operational activity owner

30
®
Establish the row mapping

31
®

32
®
Validate Query

33
®
BIRT – create the sixth query
 Row
Extract all activity realizations
 Column
Name of the operational activity
URI of the operational activity
Name of the system operational activity realization
URI of the system operational activity realization

34
®
Establish the row mapping

35
®

36
®
Validate Query

37
®
First joint data set
 Create table that relates Operational Nodes that are Capabilities to the
Operational Capability Realizations

38
®
Join based on OperationalCapabilityURI

39
®
Validate the query

40
®
Create second joint data set
 Create a table that joins the OperationalActivities to the first joint data set
 We want those OperationalActivities whose parent is an
OperationalCapabilityRealization related to a Capability that’s an Operational
Node.

41
®
Validate results

42
®
Third joint data set
 Create a table that links the Systems to the System
OperationalCapabilityRealizations (which are OperationalActivityRealizations)

43
®
Create the joint data set

44
®
Validate results

45
®
Create fourth joint data set
 Create a table that relates the System Functions to the
OperationalActivityRealizations that are linked to the System
OperationalCapabilityRealizations

46
®
Create the joint data set

47
®
Validate Results

48
®
Create Fifth Joint Data Set
 Join the Operational Activity (Query6) with the table that links the Capability to
the Operational Activity (J2)

49
®
Validate the Query

50
®
Create final joint data set
 Now, join the operational to the system (join S2 and O1)

51
®
Validate the results
 There are many columns in the resulting data set – as a results, we’ve broken the image into two chunks.

52
®
Presentation
 Now that we have the data that we need, we’ll need to present it appropriately
 We’re going to need to create a data cube, and a crosstab

53
®
Create the Data Cube
 Associate the SV5 data set with this cube

54
®
Create the groups and summary field in the data cube

55
®
Create the crosstab

56
®
Drag/drop rows/columns and summary fields
 Drag/drop System

57
®
Expose group levels for System
 Next, expose the group levels

58
®
Drop Capability Into Column

59
®
Expose groups
 And, as with the Systems, expose the groups

60
®
Now, add the measurement field

61
®
Cleaning up…
 Set vertical presentation, and hide measure header

62
®
Preview Results
 Voila! We have an SV5 per the problem definition!

63
®
Complete the report
 Edit the data cube summary field

64
®
Edit the expression
 Add JavaScript code that produces an “X” if the field is not blank

65
®
Add a label to the crosstab

66
®
The Completed SV5

67
®
Appendix
 Including parents and grandparents
