  1. Getting Started with Enterprise Architect and Subversion Gerald R. Gray, Guiding Principle Consulting

  2. Disclaimer • Not a celebrity spokes model • Not a SparxSystems representative

  3. Agenda • EA Strengths/Weaknesses • Pre-requisites • Access • Setup & Configuration • Creating common OpenSG diagrams • Model Baselines

  4. EA 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

  5. EA 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

  6. Pre-requisites • Sparx Enterprise Architect • http://www.sparxsystems.com.au/ • $135 - $699 depending on version • Subversion • Command-line client (required) • http://www.open.collab.net/downloads/subversion/ • TortoiseSVN (optional) • http://tortoisesvn.net/downloads

  7. Repository Access • UCAIUG Microsoft SharePoint credentials • Added to the Source Code Access group in the UCAIUG SharePoint user management (Tony Adams, Kay Clinard) • Coordinate with the appropriate team, ie., OpenADE, OpenADR, OpenAMIENT

  8. Installation • Install • Enterprise Architect (v7.5 or greater) • Subversion command-line client • http://www.collab.net/downloads/subversion/ • TortoiseSVN (Windows) • http://tortoisesvn.net/downloads

  9. Working Directory Creation • C:\OpenSG\Test\Working • In Windows Explorer, right-click on folder • Using TortoiseSVN repo browse to: • http://svn.ucaiug.org/svn/cimugrepo • Enter credentials if prompted • Right-click on folder in left-hand panel • Select Export… to directory created above

  10. EA Configuration • Start Enterprise Architect • Open the project • From main menu select • Project Version Control Version Control Settings…

  11. EA Configuration • Create a unique name • Select type: Subversion • Point to working directory • Subversion exe path should pre-populate • Click Save

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

  13. Common OpenSG Diagrams • Use Case • Business Process (Activity) • Integration Requirements • Sequence Diagram

  14. 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

  15. Adding a Business Process • Project Browser • Add new diagram: Activity • Open workspace, right-click for Swimlanes and Matrix… • Add swimlanes • Add Activity and flows

  16. 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

  17. Adding Sequence Diagram • Project Browser • Add diagram: sequence • Open workspace • Add Actors • Add flows (asynchronous) • Add returns (“Is Return” checkbox)

  18. Hands On Exercise • Create a package • Create a use case • Create activity • Add integration requirement • Create sequence diagram

  19. Manage Baselines • 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 • Corporate version required*
