Database Designing & Modelling; Data Migration Wizard; Advanced MySQL Capabilities. MySQL Workbench Tutorial: What is. Modeling simplifies database design and maintenance by enabling you, the data architect, to visualize requirements and resolve design issues. MySQL Workbench is a cross-platform, open-source relational database design tool that adds functionality and ease to your MySQL and SQL. HOW TO SIGN INTO EXISTING EMAIL ON POLYMAIL IOS
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. At first, the tool may seem complex to use, but with time it gets easier.
Practice makes perfect. In this tutorial, the focus will be on database design. You can do this from the installation wizard. Linux: Launch by typing the command mysql-workbench. Provide the connection details. The created connection will be displayed, as shown in the screenshot below.
After adding a new diagram, a new window will be opened, as in the screenshot below. Scenario In this tutorial, we will model and create a database that will be used to keep book details.
