Course Outline

• EA Strengths/Weaknesses
• Pre-requisites
• Creating common use case related diagrams
– Used by UCAIUG, CIMug, OpenSG, MultiSpeak…
• Model Baselines
• Versioning Setup & Configuration
• CIM Profiling
– CIMEA


Enterprise Architect: Uses and Benefits

• Supports IT system, software, and business processes
• Model, design, build, and test software
• Uses standard Unified Modeling Language (UML)
• Central repository for process and IT system information
• Interfaces with version control e.g. Subversion
• Fast, built-in or custom document generation & HTML


Enterprise Architect: Weaknesses

• May be a poor choice for complex system
diagrams
– Visio is “prettier”
– PowerPoint also an option
• Complex User Interface
– Extensive feature set may lead to confusion
– Time saving “tricks” difficult to learn
• Diagrams not useful if team doesn’t see value
– UML/BPM may be used currently at their site
– Some users intimidated by tool


Installation

• SparxSystems Enterprise Architect
– http://www.sparxsystems.com.au/
• $135 - $699 depending on version
• Enterprise Architect (v7.5 or greater)
• v9.2 recently released
• Subversion command-line client
• http://www.collab.net/downloads/subversion/
• TortoiseSVN (Windows)
• http://tortoisesvn.net/downloads


Common UCAIUG / CIMUG Diagrams

• Top Down Approach
– Use Case
– Business Process (Activity)
• Integration Requirements
– Sequence Diagram
– Profile

• Let’s look at some examples!


Adding a Use Case

• Project Browser
– New Package – grouping of diagrams
– Add new diagram: Use Case
– In the workspace add
• Actors, cases, associations
– Save changes, check-in package


Adding a Business Process

• Project Browser
– Add new diagram: Activity
– Open workspace, right-click for
Swimlanes and Matrix…
– Add swimlanes
• Create new or use classifier to
select existing actors
– Add Activity and flows


Integrations Requirements

• Addition to the Activity diagram
– Typically a hand-off from the business user to the
architect/software
– Object flow between two activities, spanning actors
(swimlanes), between two systems
– Add requirement (from common tools)
• Right-click properties
• Type dropdown: Add integration
– Change node to identify service


Adding Sequence Diagram

• Project Browser
– Add diagram: sequence
– Open workspace
– Add Actors
– Add flows (asynchronous)
– Add returns (“Is Return” checkbox)


Manage Baselines

• Corporate version required*
• Internal “version control”
– Can be used in conjunction with DBMS
• Baseline can be added to each package
• Complements import/export of XMI
– Import XMI replaces everything in a target package
– Can be compared to XMI to replace only desired
changes


Enterprise Architecture: Version Control

• Working Directory creation:
– C:TestWorking
• In Windows Explorer, right-click on folder
• TortoiseSVN ►Create repository here…
– Connecting to a remote repository:
• Using TortoiseSVN repo browse to repository
location:
– Enter credentials if prompted
– Right-click on folder in left-hand panel
– Select Export… to directory created above


Enterprise Architect: Version Control Settings

• From main menu select
– Project Version Control
Version Control Settings…
– Create a unique name
– Select type: Subversion
– Point to working directory
– Subversion exe path should
pre-populate
– Click Save


Enterprise Architect: Adding a branch

• Right-click on Package
• Select Package Control
• Select Add Branch to Version
Control…
• The key icon is added to each
package under version control


CIM EA

• Addin to Enterprise Architect
– Easy to create
• CIM UML profiles
• Generate XSDs, RDFs
• Uses CIM, MultiSpeak, and other models as reference
• Used to design message payloads, etc
• Other tools can create CIM profiles, e.g. CIMTool


Example UML Profile


Profile Design

• CIMEA integrates into the EA user interface
• Profiles built from references model, (CIM or other)
• Right-click on reference model, select
– Add In (“Extensions” in v9.x) CIM EA Create a CIM
profile…
– Give name…
– Select classes, attributes, relationships


Generating artifacts

• Using CIM EA add in facilitates quick artifacts (XSD, RDF)
generation
– Select Add In (“Extensions” in v9.x) CIM EA
Generate Artifacts
– Example CIM profile
• Change the namespace
• Change message – usually to just “m”
• Change model location – this is used for sawsdl
attributes
• Generate – and open in your favorite XML editor


Recap

• Learned how to go from
– Use case to…
– Business process to…
– Identifying integration requirements…
– Creating sequence diagrams…
• Configuring version control
• Design profile to…
– Generate an artifact
