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

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

22

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

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
