Getting Started with Enterprise Architect

This guide introduces Enterprise Architect, highlighting its strengths and weaknesses, prerequisites, installation, setup, and configuration steps. Learn how to create common OpenSG diagrams, manage baselines, and organize IT systems and business processes using the Unified Modeling Language (UML). The guide also addresses version control with Subversion, providing essential tips and resources for effective software modeling and design. Ideal for engineers and project managers seeking to enhance their modeling capabilities and drive collaboration within their teams.

  1. Getting Started with Enterprise Architect Gerald R. Gray, PhDElectric Power Research Institute (EPRI)

  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 • Subversion can be used locally

  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 • Right-click properties • Type dropdown: Add Integration • Change node to identify service name

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

  18. Manage Baselines • Internal “version control” • Can be used in conjunction with DBMS • Corporate version required* • 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

  19. Reference • EA Free Trial • http://www.sparxsystems.com/products/ea/trial.html • Subversion Documentation • http://svnbook.red-bean.com/en/1.5/index.html • EA Tutorials and Online Help • http://www.sparxsystems.com/resources/index.html • Test Repository • http://svn.ucaiug.org/svn/TestRepos/
