How to use PowerDesigner to generate the Emurr diagram of Dameng database. In view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Background:

Since the current operating systems are basically 64-bit, 64-bit software is generally installed.

However, when powerdesigner links to the Dream database, the driver required is 32-bit, so when referring to other materials, it is found that this part of the description is missing.

So sort it out a little bit for reference only.

1. Go to Dameng's official website to download the Dameng win32 bit installation package and install it.

The installation package is an ISO file, so you need a tool that can load ISO, download it yourself, and then install it.

2. Powerdesigner15 for my test. The reader chooses the version to install.

3. Create an odbc:

Description: the 64-bit driver is identified in the default management tool, so you need to go to this path and execute the database tool.

C:\ Windows\ SysWOW64\ odbcad32.exe

Then select: user DSN- > add-> Select DM7-32-bit driver; configure the Dameng database that needs to be accessed. I am testing the local 64-bit Dameng database, which can also be a remote database.

4 、 powerdesigner:

Establish a new model: select physical data model to determine.

Select: file-> reverse engineer-> database.

When selecting the driver, because powerdesigner does not have a separate Dameng database driver option, so choose the ODBC3.0 driver.

Then select the 32-bit odbc driver just configured, and then complete the connection between powderdesigner and Dameng database.

Next, you can choose which objects need to generate the Emurr diagram, and you can choose to specify the objects under the schema.

This is the answer to the question about how to use PowerDesigner to generate the Emurr map of Dameng database. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
