Prerequisites · Install MySQL Workbench · Get connection information · Connect to the server by using MySQL Workbench · Create a table, insert data. Launch MySQL Workbench · From the Home window click the > icon to the right of Models · Choose “Create EER Model from Database” · The Reverse. This section will create a new ER model and then translate it into a physical MySQL database. On MySQL Workbench, navigate to File > New. TEAMVIEWER SYNOLOGY Связала прокладывая при пакетов на леску.

MySQL Workbench has a visual performance dashboard. The visual performance dashboard enables database administrators to view key performance indicators. Image source. Workbench is one of the MySQL products. For this installation, I recommend the default configurations, as shown in the screenshot below. Make sure there is a connection to the MySQL Server local instance, as shown in the screenshot below. Save the model. Refer to the screenshot below. In this tutorial, we will model and create a database that will be used to keep book details.

The database should store books with author and publisher details. We will skip the database normalization process details. We will use the information in the tables below to design the ER model. All the column names have been defined.

Primary keys, foreign keys, and datatypes are also outlined. MySQL Workbench allows us to create tables, edit the attributes, and create relationships between the tables. The window has different panels highlighted in different colors. The vertical toolbar has different tools used in creating EER diagrams. The screenshot below shows all the tools. Hovering the mouse pointer on each tool will show the name or the function of each tool.

We are going to add three tables to the EER model. The animation below shows the process of adding a table and the columns. There is a one-to-many relationship between the book and the publisher. We will use the relationship tools to add relationships. To create a one-to-many relationship, make sure that one of the tables has a primary key. Select the appropriate relationship tool. In this case, we are going to use the one-to-many non-identifying relationship.

In this case, it is the book table. Click the table containing the referenced key. In this case, it is the publisher table. To change the foreign key properties, double click the connection line to open the relationship editor. There is a many-to-many relationship between the book and the author. Select the many-to-many relationship tool.

Click on the book table, then click on the author table as shown in the animation below. You can find the EER diagram workbench file created in this tutorial on Github. The visual database model created can be transformed into a physical database. This process is known as forward engineering.

This is easier than writing the code manually. Select the objects you would like to include in the EER diagram. These will include tables, views, routines, users, and triggers. In this exercise, we only have tables. In this step, we are provided with the generated SQL script.

Find the SQL file generated in this tutorial on Github. This is the final step. Click finish to commit. The database created will be as shown in the screenshot below. Reverse engineering enables us to have a better view of an existing database.

A physical database is converted to an EER diagram. We will be reverse engineering the database we created earlier. In this tutorial, we will use the live database we created in the forward engineering section. Create a new connection to the MySQL Server or select an existing one, as shown in the screenshot below. Review the information displayed and make sure that the connection was successful, then click NEXT.

Select the schema you would like to reverse engineer. In this case, select booksdb , then click NEXT. The results of the tasks carried out are displayed in the wizard below. Review the results, then click NEXT. We are prompted to select the objects to reverse engineer.

By default, all the available objects are selected. Leave the default options, then click NEXT. The wizard shows the reverse engineering progress. In the screenshot below, the process was successful. In case of an error, check error details by clicking Show Logs. MySQL Workbench is such a useful tool.

It can be used by MySQL database administrators, system developers, and database developers. To create a new database using SQL query, follow the steps given in the following screenshot. First, create a SQL file red box number 1 in the following screenshot , write the commands red box number 2 , press the refresh button red box number 3 , and see the recently created schemas red box number 4. You can also create a database from the Navigator pane.

Right click in the Navigator pane, select Create Schema , name your database, and click apply as we already did in method 1. Open your command prompt as an administrator. Go to the path where MySQL is installed and use the following command to login:. Here -u means username, -p means password.

Our username is the root, and the password is , yours may be different. Write the SQL command for creating a new database and make sure whether it is created or not. It just needs a little bit of practice. It includes creating a database using navigator pane, menu bar and SQL command. You can also create a new schema using the command prompt as well.

Now, you can see your connection as follows. You will see the following screen, name your schema, and click Apply button. The following window will show up; click on Finish. Go to the path where MySQL is installed and use the following command to login: mysql -u root -p Here -u means username, -p means password.

Right now, we have the following databases.
