Möbius Data Manager

Introduction

Möbius provides the ability to store solver results in a PostgreSQL database. Instructions for setting up a database to work with Möbius are detailed in Section C.2. Once the results database has been successfully set up, the user can store any results from simulation and analytical solver executions in it.

Several third-party utilities exist for accessing and managing general data in PostgreSQL databases. PGAdminIII (http://www.pgadmin.org) is a very popular graphical administration tool, and PostgreSQL also distributes a simple text-based command-line tool. However, these tools work on databases without any notion of how or why the data is organized the way it is.

The Möbius Data Manager tool seeks to fill the role of a graphical interface on Möbius results databases in a way that is intuitive and familiar for Möbius users. The Möbius Data Manager allows users to connect to Möbius results databases and manage, organize, and export the data they contain. Möbius users can launch the Möbius Data Manager by clicking on the Utilities$\rightarrow$Mobius Data Manager menu item in the Project Manager window.

Connecting to the Database

When you first launch the Möbius Data Manager, you will immediately be prompted to enter the connection details for the database you’d like to work with. These are the same details you entered in the Database Settings dialog window (section C.2.3).

The Host field should have either the fully qualified domain name or the IP address of the computer running the PostgreSQL database. The Username and Password fields should contain the PostgreSQL user credentials. The Database field should contain the name of the Möbius results database on the PostgreSQL server.

Once you have entered valid details, click Login to connect to the server and begin the Data Manager session.

To log in to a new connection, you may start the new connection by clicking on the File$\rightarrow$New Connection menu item in the Möbius Data Manager.

Saved Connection Details

Some connection information can be saved between sessions so that the connection details don’t need to be typed in each time. By default, the Data Manager always stores the details from the most recent connection. The next time the Data Manager is launched, the details from the last session will be automatically filled into the login dialog.

For the sake of security, the Möbius Data Manager never stores passwords. You must always enter your password when using stored connections.

Connection details can also be manually saved with a user-specified connection name. In the Login window, highlight the text in the Connections field and replace it with a name, for example, “Work DB Server.” Fill in the remaining details and then click the Save Connection button. The next time you are prompted to login, the new saved connection details will be in the drop-down list. Selecting it in the list should populate the fields with the saved information.

Should a set of saved connection details no longer be needed, you can easily delete it. Begin by selecting the connection from the drop-down list and click the Delete Connection button to permanently remove it from the list. This does not affect the database server or any data on it.
