Managing Connections to Projects

An Enterprise Architect project is used for storing and managing the components of one or more UML models. The Professional Edition of Enterprise Architect works on file-based projects (.qea, .feap or .eap/.eapx files). If you are using the Corporate Edition (or above), you can also use one of a number of DBMSs such as MySQL, SQL Server, Oracle, or a Cloud Based server to host the project repository.

When you select to open a project, you can:

  • Select a shortcut to a recent project, to open it
  • Browse for another existing project to open
  • Remove a shortcut from the list of recently-opened projects
  • Specify connection details for opening a project hosted on a DBMS
  • Connect to a project via the Cloud
  • Create a new Enterprise Architect project file

Connect to Server

Click on this button to specify connection details for opening a server-based Enterprise Architect repository. The 'Open Server Connection' dialog displays; start to define the connection to the project's server-based repository.

You can also click on the drop-down arrow and select:

  • 'Native Connection' - the 'Open Server Connection' dialog displays
  • 'ODBC Connection Wizard' - the Windows 'Data Link Properties' dialog displays; you can also use this method to define the repository connection
  • 'Connection string' - the 'Connection String' dialog displays; type in or paste the connection string and click on the OK button to connect directly to the project

Note that you can also display the 'Connection String' dialog directly, by selecting the 'URL' option on the Start page.

Connect to Cloud

Click on this button to connect to a project through the Cloud. The 'Cloud Connection' dialog displays, on which you specify the server URL and model name to access via the Cloud.

Recent Projects

This panel lists the most recently opened projects, up to a maximum of ten. To open one of these projects either double-click on the name, or select it in the list and then click on the Open button.

Each project name is shown with its access path. You can edit the access path by right-clicking on it and selecting the 'Edit Connection String' context menu option; make the changes on the 'Connection String' dialog, and click on the OK button

Similarly, if the project has a connection string (not a shortcut), you can change the name of the project by right-clicking on it and selecting the 'Edit Project Name' menu option; type a new name in the 'Edit Project Name' dialog and click on the OK button.

The list of recent projects is also displayed:

  • On the Start Page, under the 'Recent' heading
  • As a drop-down menu under the Open Project button on the Default Tools toolbar
  • With the Project list list of options

Remove Selection from List

Click on a project name and click on this button to remove that project name from the 'Recent' list.
