Create a Project in a PostgreSQL Database

To create a project in a repository on PostgreSQL 7, 8 or 9, you work through these stages:

  • Stage 1: Create an empty database repository  and set up the data tables
  • Stage 2: Set up the PostgreSQL ODBC Driver
  • Stage 3: Perform a project integrity check on the project file you are using as a base (optional, but recommended)
  • Stage 4: Transfer the data
  • Stage 5: Connect to the repository to open the project

Prerequisites

  • A machine with PostgreSQL 7.3.2 or higher installed and running
  • psqlODBC, version 7.03.01.00 or higher has been installed (do not use version 8.3.4 or 8.4.1)

Perform a Project Integrity Check

Step

1

In Enterprise Architect, open the file-based project or template from which you are creating the project on the repository.

2

Select and run 'Project | Data Management | Project Integrity Check'.

This ensures your project data is 'clean' before being copied to the repository.

Open Enterprise Architect.

(If the 'Open Project' dialog displays, click on the Cancel button to open with no project loaded.)

2

Select the 'Project | Data Management | Project Transfer' menu option.

The 'Project Transfer' dialog displays.

3

In the 'Transfer Type' panel, select '.EAP to DBMS'.

4

In the 'Source Project' field, type the name of the project file to copy to the repository.

If the .EAP file has Replication enabled, this must be removed before performing the transfer.

Remove Replication

5

At the right of the 'Target Project' field, click on the button.

The 'Datalink Properties' dialog displays.

6

Select 'Microsoft OLE DB Provider for ODBC Drivers' from the list.

Click on the Next button.

7

On the 'Use Data Source Name' field, click on the drop-down arrow and select the ODBC Data Source you configured to point to your new database.

Click on the OK button. The 'Project Transfer' dialog redisplays.

8

If required, select the 'Logfile' checkbox and type a path and filename for the data transfer log file.

9

Click on the Transfer button to begin the data transfer process.

10

When the process is complete, you have created a project on a PostgreSQL database and can now connect to it and open it from Enterprise Architect.

Notes

  • During the transfer, if an error message displays reporting '...nonstandard use of \\ in a string literal...', set the server variable in the postgresql.conf file to: escape_string_warning = off
