Next you need to create your MySQL Server Connection which contains details about target database server including how to connect to it.
Wizard 3. As a beginner you can create a connection for a locally installed server. A new window opens named Configure Local Management. Click Next button to continue.
Next the Wizard will test connections to database. If test fails, go back and correct database connection parameters. Next it will open a pop up window asking your root password to test your connection with the local mysql server instance.
Enter your password and press OK 6. Else if all tests are sucessful click Next to continue. After that a new wizard will open about Local Service Management - It lets you switch between multiple mysql severs installed on one machines. Next you can review current configurations.
After reviewing the configurations, Click Finish to finsh server cofiguration Next Step is to setup a connection, which can be used to connect to server.
If you have not created a connection already, you can use the default values given. Click OK. If the entered password for the user is correct then the following screen will show. Click on both OK buttons and you will be good to go.
A new instance is shown in the homepage Double click and start querying. Summary MySQL is an open source relational database that is cross platform.
MySQL supports multiple storage engines which greatly improve the server performance tuning and flexibility. Prior to version 5.
Having given our schema a name, we can now add a table to the model. This is achieved by double clicking on the Add Table button in the Tables panel:. Change the table name to inventory and then select the Columns tab to begin the process of adding columns to the table:. By default, the workbench will create a non-null primary key named idinventory. For the purposes of this exercise we will keep this column, though in practice this can be changed.
Select the second line, double click in the Column Name field and name the column product. Each of these should be declared as non-null by checking the boxes in the NN column:. The diagram illustrated in the following figure will then be generated:.
Having created a model, the next step is to generate a SQL script from the model and feed it through to a database server where it will be executed to create the physical database and table. In the resulting dialog, a range of selections are available to filter and modify the script that will ultimately be generated. Unless you have specific requirements, leave the default selections unchanged. In addition, the objects that are to be generated may also be selected.
Assuming the script appears as expected given the initial model from which it has been generated, click Next to specify the server to which the script is to be sent or save the script if it is to be used later, perhaps within the SQL Editor or mysql client:.
Select the stored connection to which the script is to be sent together with any other connection parameters that are required, click on Execute and enter the password if required to do so. The success or otherwise of the execution will then be reported in the following screen. Assuming a successful operation, the new database will now be present on the designated database server.
In addition to aiding in the design of new models, a model may also be generated from an existing database a concept referred to as reverse engineering. To reverse engineer an existing database, select the Create EER Model from Existing Database link from the Database Modeling column of the MySQL Workbench home screen and configure the connection to the desired database server in the resulting dialog.
Having connected successfully and fetched the database information proceed to the next screen to select the schemata to be reverse engineered. A good example here if you do not have any existing databases is to reverse engineer the mysql database the database used internally by MySQL.
