HawkBridge - Picture This! Using CA 2E with Graphical Tools v4

Picture This! Using CA 2E with Graphical Tools
CA 2E Track
Darryl Millington, HawkBridge Pty Ltd (Australia)

 Visualising CA 2E database relations from graphical tools such
as CA ERwin and Microsoft Visio increases developer
productivity and enhances communication between IT and the
business. This session will cover out-of-the box solutions
providing a convenient method of transferring data model
information from CA 2E data models where a picture conveys a
thousand words.

 Higher level visual design tools do not support the full CA 2E unique data
modeling language
 Structure Files
– Uses Known-by relation for all file relationships
– Defined in the physical data model for CA ERwin
 Includes Relations
– Uses a non-defining relationship for CA ERwin and MS Visio
– Uses Is-A relationship for CA Plex
– Uses Has relations where entries are renamed for CA Plex
 Database Relations
– Relationship direction is reversed in CA Erwin
 Span Access Paths
– Treated as separate access paths for each format
– Each access path may be based on a different file
CA 2E Unique Modeling Language

 Freedom/ERwin the CA 2E to CA ERwin integration tool
 Transfers CA 2E data model information to CA ERwin data
models

Data Model

Step 1: Run the HCRTERWERD Command
to generate a physical file containing the
exported XML

Uses the CA 2E model object select
program to select an existing model
object

Uses the CA 2E model object list
commands to edit
the list of selected objects

Generates an CA ERwin compliant XML
import file

Step 2: Transfer the generated physical file
to the IFS or PC

Specify a standard
ASCII file transfer

Exclude the end of file indicator

Message indicates file transfer has been
successful

Step 3: Open XML file directly in CA ERwin
without the need for other intermediate
tools

Message indicates XML import has been
successful

Use the Layout Entire Diagram option to
produce optimal layout

Open XML File in CA ERwin

names for objects with model view in left
pane

22
Physical model shows internal system
names for objects with domain view in
left pane

Freedom/Visio Overview
 Freedom/Visio the CA 2E to Microsoft Visio integration tool
 Transfers CA 2E data model information to Microsoft Visio
diagrams

Step 1: Run the HCRTVSOERD Command
to generate a physical file containing the
exported XML

30
Generates an Microsoft Visio compliant
XML import file

Transfer XML File to PC
31
Step 2: Transfer the generated physical file
to the IFS or PC

Open XML File in Microsoft Visio
32
Step 3: Open XML file directly in Microsoft
Visio without the need for other
intermediate tools

33
Use the Lay Out Shapes option to produce
optimal layout

34
Implicitly selected entities which were not
in the initial list are grey with diagonal
stripes

35
Select one or more entities to run the
“Show Keys Only” or “Show Attributes”
add-in against

36
Re-use the Lay Out Shapes option to
produce optimal layout

37
Diagram can now be manually adjusted to
fine tune the layout

Session Summary
 Text based modeling language of CA 2E for defining database
relations is quite powerful
 In large data models it can become difficult to appreciate and
understand object relationships
 Conversion to a graphical data model such as CA ERwin or
Microsoft Visio where a picture can convey a thousand words
increases developer productivity
